Risk of death caused by coming into contact with high-voltage parts although ignition is turned off. - AS15.15-Z-0001-01A

After ignition is turned OFF, only disconnect the plug on the ECI power pack after first waiting for 3 minutes.

After ignition is OFF there is still a voltage of more than 48 V at plugs 9 and 16 on the ECI ignition system power pack. Remove plug from ECI power pack unit only after first waiting for 3 minutes. The voltage is then no longer dangerous because the capacitor has had time to discharge.
For safety reasons the 180 V may only be measured with the corresponding insulated measuring equipment and lines.

Notes on ignition circuit shutoff test - AH07.00-P-3004-03WA

Engine 113

The ignition circuit shutoff can only be carried out on engine 113. Switch off ignition circuit for not more than 20 seconds in order to pinpoint a fault. If an ignition circuit is switched off for more than 20 seconds, faults are stored in the fault memory (e.g. misfiring damaging TWC, O2 sensor upstream TWC). In this case, erase the fault memory.

Notes on ignition coil characteristics of ignition systems - AH15.10-P-1001-01A

Engine 104, 111, 112, 113, 119, 120

In the case of the twin-spark ignition coil with kV pickup in ignition systems ME-SFI 2.1 and HFM-SFI, no measurement facility exists at the ignition coil using the kV pickup although a kV pickup is fitted. It is only possible to test the primary ignition circuit with adapter cable A.

ME fuel injection and ignition system (ME), DTC memory - AD07.61-P-4000L

ENGINE 137.970

	Risk of death caused by contact with parts conducting high voltages.	Do not touch parts which conduct high voltages. Persons who wear electronic implants (e.g. heart pacemakers) must not perform any work on the ignition system.	AS15.10-Z-0001-01A
	Risk of fatal injury when touching parts conducting high voltage when the ignition is switched off	After ignition is turned OFF, only disconnect the plug on the ECI power pack after first waiting for 3 minutes. The voltage in the condenser dissipates in this time.	AS15.15-Z-0001-01A

2	Fault storage	After expiry of test duration and fault
	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	Following two successive driving cycles with faults
3	Checking frequency	Continuous
4	Checked signal or status	Signal from pressure sensor downstream of throttle valve actuator
5	Fault setting conditions
	Short-circuit to positive/cable open-circuit	Fault when signal voltage greater than 4.8 V with ignition ON.
	Short-circuit to ground	Fault when signal voltage less than 0.2 V with ignition ON.
	Signal implausible	With the starter turning and at an engine speed up to 300 rpm, the signal must change (activity check). After starting, the difference in pressure between the pressure at ignition ON and a performance map is compared once in the driving cycle.
	Plausibility	The signal may deviate only slightly from the performance map value. The stored performance map value is dependent on: throttle valve angle, engine speed, charge temperature and ambient pressure.
6		In the event of a fault, power is reduced (emergency mode), as the pressure sensor downstream of the throttle valve actuator detects the engine load and thus provides the critical input signal for pressure control. Pay attention to the blue color coding at the pressure sensor downstream of the throttle valve actuator.

6		Until the fault is cleared, travel continues using a speed-dependent substitute value for the performance map. Check hose line to the pressure sensor upstream of the throttle valve actuator for leaks. Pay attention to blue color coding at the pressure sensor upstream of the throttle valve actuator. If the pressure sensors are swapped (color coding) the engine switches off after starting.

3	Checking frequency	With ignition ON, at engine start and continuous
4	Checked signal or status	Pressure values for plausibility and comparison with stored performance map values.
5	Fault setting conditions	Fault when the pressure values are implausible in comparison with one another or the deviation from the performance map is too great. In intake operation, the pressure difference between the ambient pressure and the pressure downstream of the air filter may not be as high. With the throttle valve wide open, the pressure values from the pressure upstream and downstream of the throttle valve must be almost identical.
6	Check prerequisites	No fault in ambient pressure sensor (in ME-SFI sensor) No pressure sensor fault downstream of throttle valve actuator (B28/7) No fault at pressure, pressure upstream of throttle valve actuator (B28/6) No fault in pressure sensor downstream of air filter, left cylinder bank (B28/4) and pressure sensor downstream of air filter, right cylinder bank (B28/5) No fault in boost pressure control (electrical, mechanical and pneumatic functions OK).
7		If a fault occurs, the throttle valve angle is restricted and only the basic charge pressure (approx. 300 mbar) still achieved (lack of power). Check hose line to the pressure sensor upstream of the throttle valve actuator for leaks. Check color coding of the pressure sensor. If the pressure sensors are swapped, the engine switches off after starting. In the event of an error in the pressure value from the pressure sensor downstream of the throttle valve actuator (B28/7), no further tests are possible. In the event of an error in the pressure value from the pressure sensor downstream of the air filter, right cylinder bank (B28/5), the test for the pressure sensor upstream of the throttle valve actuator (B28/6) is blocked. In the event of an ambient pressure fault, the following tests are blocked: Pressure sensor downstream of air filter, right cylinder bank (B28/5) Pressure sensor upstream throttle valve actuator (B28/6) Tank pressure sensor (B4/3)

8		If faults are recognized at the same time for the O₂ sensor upstream and downstream of the TWC it is generally just the O₂ sensor downstream of the TWC which is defective. If the O₂ sensor downstream of TWC is so defective that the sensor voltage remains slightly under the regulating threshold then the lambda control is enriched over T _V . Monitoring of the correction variable of the O₂ sensor upstream of TWC then also incorrectly detects a faulty O₂ sensor upstream of TWC. If the correction variable for the O₂ sensor upstream of TWC is exceeded, monitoring of the O₂ downstream TWC continues.

For engine 275 and 285, a catalytic converter and lambda control are assigned to each cylinder bank.

Check procedure

The engine control unit determines the lambda mean value from signals from the O₂ sensors downstream of TWC. This value is compared with a stored value for optimum exhaust emissions.

If the deviation is too large after a number of measurements, a correction variable (time delay ± T_V )is determined for the lambda control.

The correction variable (value for new O₂ sensor approx. 0) makes it possible to compensate for aging of the O₂ sensor upstream of TWC within certain limits. If the correction variable exceeds the limit value, the O₂ sensor upstream of the TWC must be replaced.

In addition, allowance is made for the period of the signal supplied by the sensor upstream of TWC. If no sensor state change takes place, the lambda control is not active and therefore a two-sensor control is not possible either.

The effect of the firewall catalytic converters is monitored based on the O₂ sensor signals downstream of the TWC.

7		The average cycle duration is compared with the upper and lower limit value. In the case of the effect of simultaneous faults on the catalytic converter tighter limits apply so that a fault can be recognized more quickly.

6	Check prerequisites	Exhaust gas and catalytic converter temperature 340 to 500°C
7		The internal resistance of Nernst cells is used as a criterion for the testing. The internal resistance of Nernst cells must be within tolerance for the specified exhaust and catalytic converter temperature. If, in addition to this the faulty voltage supply for O₂ sensor heating is stored, then the voltage supply should be checked first (connector, line, fuse). If O₂ sensor heating is faulty, check: Check connector, line and fuse. For a short circuit to ground: measure the resistor between the O₂ sensor housing and the sensor heater (connection 1 or 2). If value less than 100 Ω, replace the O₂ sensor. For a short circuit to battery voltage: check the cold resistance (+25°C) of the sensor heater between connection 1 and 2. If less than approx. 4.5 Ω, replace O₂ sensor. For line discontinuity: check the cold resistance (+25°C) of the sensor heater between connection 1 and 2. If greater than approx. 12 Ω, replace O₂ sensor. Use of cleaning or greasing fluids (sprays) and evaporating greases on the O₂ sensor or on the screw-in thread is not permissible. The screw-in thread must only be lubricated with the released grease. Broaching of the sensor lines is not permissible.

7		Actuation of every O₂ sensor heater is checked for open circuit and short circuit (to ground or battery voltage). A short circuit to ground and a cable breakage will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. In case of a fault in the power supply also the fault "O₂ sensor heater, internal resistance" is recognized. If O₂ sensor heating is faulty, check: Check connector, line and fuse. For a short circuit to ground: measure the resistor between the O₂ sensor housing and the sensor heater (connection 1 or 2). If value less than 100 Ω, replace the O₂ sensor. For a short circuit to battery voltage: check the cold resistance (+25°C) of the sensor heater between connection 1 and 2.

Misfires through faults in the ECI ignition system If ignition does not take place misfiring occurs. If in addition to misfiring faults there are also ECI faults stored, then start the troubleshooting Begin ECI ignition system. ECI faults are not, however, always stored at the same time. If a cylinder does not fire (compare current ion current signals) then check line with the ignition trigger signals between ECI ignition module and ME-SFI [ME] control unit for discontinuity. Misfires due to fuel starvation If combustion misfires are recognized, another fault code P203A (P0460) is output if the level in the fuel tank is too low. This information indicates combustion misfires due to fuel starvation. A lack of fuel pressure can be the cause (e.g. if the fuel filter is clogged, fuel pump, fuel pump control unit or fuel pressure sensor defective). Misfiring because of miscellaneous causes Combustion misfires may be caused by many faults in the injection system. Usually in this case other component or function faults are stored, in addition to the misfire fault. The cause may also be due to faults in the engine mechanics.

7		The three-way catalytic converter is evaluated on its ability to store oxygen. The oxygen stored during a lean-mixed phase is either completely or partially consumed during a rich-mixed phase. The storage capacity and thus also the HC conversion are reduced through aging. If the fault codes for the TWC and for the O₂ sensors are issued identically, the O₂ sensors should be replaced first. If then a TWC fault is no longer detected, and if the effect of the three-way catalytic converter has been slightly reduced, it does not need to be replaced yet.

7		The test for minor and micro leaks is aborted if an excessive lean correction of the lambda closed-loop control takes place during the vacuum buildup. Operation of the purge control valve (Y58/1) is checked at the same time as it is actuated. If the closed valve jams or it is blocked, a gross leak fault is stored. In the case of a gross leak the display in the instrument cluster shows "Tank cap missing" and the fuel reserve display flashes. If the activated charcoal canister shut-off valve jams open the fault major leak or fuel tank cap missing is stored. In the event of faults, check all hose lines (it hisses clearly with a leak in excess of 3 mm in size) The tests are not inhibited if there is an implausible fill level resulting from a faulty fuel gage sensor.

Any checks for leaks must be capable of detecting leaks from as small as 0.5 mm in the purge system. To do this a pressure test is carried out with the engine idling and with the vehicle stationary

Testing takes place in three stages:

Test for major leaks
Test for a minor leak (equal to or greater than 1 mm)
Test for a micro leak (equal to or greater than 0.5 mm)

Test for major leaks

The activated charcoal canister shut-off valve (Y58/4) is closed and the purge control valve (Y58/1) opened. The intake manifold vacuum flows to the fuel tank and a vacuum builds up in the fuel tank. This is detected by the fuel tank pressure sensor (B4/3).

If there is no vacuum build-up in the fuel tank (approx. -6 mbar within approx. 15 seconds), there is a major leak (e.g. fuel tank cap open, loose hose line). The diagnosis is terminated and the fault major leak in purge system is stored.

If the ME-SFI [ME] control unit recognizes a major leak in the system, the fuel reserve warning lamp in the instrument cluster flashes and "CHECK FILLER CAP" appears in the multifunction display.

Test for a minor leak

The purge control valve (Y58/1) is closed once a certain vacuum exists (approx. -6 mbar). The system is now likewise closed. The vacuum is them measured for approx. 30 seconds. It must not drop any faster than 0.3 to 0.5 mbar per second (depending on the level of fuel in the tank). If the vacuum drops more rapidly, there is a minor leak.

Check for micro leakage

If no minor leak has been detected, the purge system is briefly enabled and a vacuum of approx. -6 mbar is built up again. The vacuum must not drop any faster than 0.1 to 0.15 mbar per second for a closed system (depending on the level of fuel in the tank).

The reduction in the vacuum depends on the fill level in the fuel tank and on the degassing of the fuel. Degassing of the fuel is measured for a short time prior to the test and is allowed for in the fault statement. No test is conducted during the driving cycle if the fuel tank is filled to less than 30 %.

The activated charcoal canister shut-off valve (Y58/4) is reopened after the tests have been conducted.

3	Checking frequency	Continuous
4	Checked signal or status	Voltages and signals at pedal value sensor
5	Fault setting conditions
	Voltage difference between signal 1 and signal 2	The signals may not deviate from one another in excess of 8 % (from idle position to approx. half the accelerator pedal travel). For comparison purposes, signal 2 is multiplied by 2.
	Short circuit to positive	Fault when signal 1 is greater than 96% of the supply voltage (e.g. 4.81 V with 5.0 V supply voltage). Fault when signal 2 is greater than 99% of the supply voltage (e.g. 2.475 V with 5.0 V supply voltage).
	Open circuit	Fault when signal 1 is less than 4% of the supply voltage (e.g. 0.2 V with 5.0 V supply voltage). Fault when signal 2 is less than 2.7% of the supply voltage (e.g. 0.0675 V with 5.0 V supply voltage).
	Power supply	Fault if voltage is greater than 5.6 V. Fault if voltage is less than 4.39 V.
6	Check prerequisites	Engine running The signal comparison and the interruption check are only enabled when the idle speed threshold is obtained (signal 1: 0.2 to 0.5 V; signal 2: 0.1 to 0.4 V). Briefly operate accelerator pedal.
7		In the event of an error at signal 1, it is switched over to signal 2 and emergency mode is activated. In the accelerator pedal sensor internal circuit, the supply voltage for sensor 2 is split. Signal 2 is also split. Test sequence: voltage supply, short-circuit to positive, interruption, voltage difference between signal 1 and signal 2. If the brake pedal is operated during travel, only the idle speed values from the accelerator pedal sensor are accepted. If necessary, substitute values are created by the engine control unit and the signals rejected by the accelerator pedal sensor. Kick-down is detected by the accelerator pedal sensor when the function is activated in variant coding. Kick-down detection takes place when: Signals 1 and 2 remain in the full load range for a particular period. The signal 1 ranges as a percentage of the supply voltage: up to 4%: interruption, signal too low, emergency mode is activated 4 to 9.4%: idle speed range 9.4 to 81% partial-load range 81 to 96% full-load range above 96%: short-circuit to positive, signal too high, emergency mode is activated.

2	Fault storage	After expiry of test duration and fault
	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	no activation
3	Checking frequency	Continuous
4	Checked signal or status	Actuation of actuator motor, close throttle vale direction
5	Fault setting conditions	Current at actuator motor greater than 4 A on many occasions for longer than 1 s.
6	Check prerequisites	Throttle valve angle smaller than 12° (position for mechanical actuator limp-home mode) Battery voltage between 8 and 17 V
7		If the throttle valve jams, adjustment errors can occur at small throttle valve angles and thus safety fuel shutoff or throttle valve actuator mechanical emergency mode is requested. To prevent this, emergency mode is started temporarily with the following functions: The specified throttle valve angle is adapted (throttle valve can stay open) The engine torque is corrected by ignition angle adaptation The idle speed control is switched off Emergency mode is switched off when the voltage at the actuator motor is OK again. If a temperature below -30°C is stored in the freeze frame data, the throttle valve may also have jammed due to the formation of ice. Delete fault if there are no complaints about the engine running and no further faults are stored.

	Short circuit to positive	Fault if signal 1 is greater than 4.686 V or signal 2 is greater than 4.882 V.
	Short circuit to ground/open circuit	Fault if signal 1 is less than 0.176 V or signal 2 is less than 0.118 V.
6	Check prerequisites	Engine speed greater than 1400 rpm
7		Both actual value potentiometers work in opposite directions. In the event of a fault at an actual value potentiometer, "Actuator-Emergency Mode-electrical" is selected and the vehicle continues with the other potentiometer. To establish which potentiometer is OK, a comparison of the throttle valve angle with the intake manifold pressure and pedal value sensor position is performed. The throttle valve angle is restricted at "Actuator-Emergency Mode-electrical". In the event of a fault at actual value potentiometers, the throttle valve actuator is switched without power and safety fuel shutoff is activated. In doing so, an engine speed of approx. 1300 rpm is achieved by switching the injectors on and off (noticeably surging engine operation).

7		The "Spark Plug a or b" fault only appears alone for approx. 3000 to 5000 km. After this distance is covered, the spark plug damage is then so great that misfirings are also detected for the respective cylinder. If large differences are detected at the spark plugs of a cylinder the spark plug with the small ionic current signal is defective or extremely carbon-fouled. If, after replacing the affected spark plug, the ionic current signal is at zero, the ignition coil is faulty and the corresponding ignition module must be replaced. In the event of smoke traces (spark gaps) at the ignition coil seals, the insulation resistance is too low and the ionic current signal small. Replace respective ECI ignition module since the ignition coils are predamaged due to the spark gap. To prevent damage to the die-cast housing, only remove and install the ECI ignition modules according to the instructions! Replace the seals at the spark plug connectors each time the ignition modules are removed or installed.

	(Fault code according to OBD)	P20E2 Charge pressure too high (-)
2	Fault storage	After expiry of test duration and fault
	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	no activation
3	Checking frequency	Continuous
4	Checked signal or status	Charge air pressure value depending in the performance map (pressure conditions downstream/upstream of compressor) Values from the pressure sensor upstream of throttle valve actuator (B28/6) to pressure sensor downstream of air filter, for the right cylinder bank (B28/5).
5	Fault setting conditions
	Boost pressure too low/too high	Deviation from the performance map value to large
6	Check prerequisites	no fault in pressure sensor boost pressure control adapted
7		the closed throttle is closed at an excessively high boost pressure to protect the turbocharger. Causes for an excessively low boost pressure could be: Leaky charge air ducting Charge air temperature greater than 70°C due to air in the low temperature cooling circuit or a fault in actuation of the charge air cooler circulation pump Boost pressure control pressure transducer (Y31/5) has a short circuit to minus or line discontinuity, boost pressure control pressure transducer is defective Hose line to pressure sensor upstream of throttle valve actuator (B28/6) leaky Deceleration air valve leaky due to cracked membrane (leak test) Turbocharger blocked or sluggish, e.g. due to a foreign object in the compressor housing. If a turbocharger stops then the boost pressure will fall over this unit. Boost pressure control valve (wastegate) does not close, e.g. due to a loose or bent control rod. If the boost pressure control valve on a turbocharger is hanging open then there complaint of a loss of performance when driving off. Air filter dirty Altitude or pressure sensor for ambient pressure in engine control unit defective Fuel grade inadequate (RON 98 required). Causes for an excessively high boost pressure could be: Electrical line to boost pressure control pressure transducer (Y31/5) has a short circuit to positive Leaky or switched around hose lines between charge air cooler, boost pressure control pressure transducer and vacuum cell Boost pressure control valve (wastegate) jammed closed Control rods to the boost pressure control valves (wastegate) loose.

1	Fault code	P2002 Charge air cooler circulation pump (M44), actuation (-)
	(Fault code according to OBD)	P20E1 Charge air temperature too high (-)
2	Fault storage	After expiry of test duration and fault
	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	no activation
3	Checking frequency	Continuous
4	Checked signal or status	Current and voltage on the charge air cooler circulation pump relay Signal from charge air temperature sensor
5	Fault setting conditions
	Short circuit to ground	Voltage lower than 4 volts
	Short circuit to positive	Current higher than 4.2 A
	Open circuit in wiring	No voltage on the charge air cooler circulation pump relay, approx. 4 to 8 V on under no load output of the ME control unit
6	Check prerequisites	Battery voltage between 8 and 17 V
7		Actuation is checked for a line interruption and short-circuit (to ground or battery voltage). A short circuit to ground and a cable breakage will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. This means that the charge air temperature can go above 70°C (loss of performance). Model 240: diagnosis locked out because the charge air cooler circulation pump relay (N10/9kO) in the passenger-side SAM control unit with fuse and relay module (N10/9) is actuated by its own output stage which is not checked by the engine control unit.

Differences to the other model series:
- Installation of the ME-SFI [ME] control unit (N3/10) in the cover for the front fuse and relay module. The construction form of the ME-SFI [ME] control unit was adapted appropriately (housing made out of die-casting).
- ME-SFI [ME] control unit with gateway function between the drive train CAN (CAN-C) and the chassis CAN (CAN-B)
- LIN interface between the ME-SFI [ME] control unit and alternator (G2).
- The camshaft Hall sensor, left cylinder bank (B6/2) is no longer needed.
- Fuel pump control unit (N118) is a CAN subscriber and can be diagnosed. Fuel pressure specification is by the ME-SFI [ME] control unit to the fuel pump control unit.
Up to 02/2006 installed (ME-SFI 2.7.1)
From model refinement 3/2006 with ME-SFI 2.7.2 installed:
- Camshaft Hall sensor, left cylinder bank is no longer needed.
Changes for ME-SFI 2.7.2:
- Intank fuel pump (M3/1) is no longer needed.
The fuel pump (M3) with 3 windings is actuated by the fuel pump control unit phase shifted.
Changes for ME-SFI 2.7.2 from 01.12.06:
- Fuel pressure sensor (B4/7) is now measuring in absolute terms and possesses a new connection assignment.
- The fuel pump control unit was adapted.
Changes for ME-SFI 2.7.2 from 01.09.2006:
- Fuel pump control unit is a CAN subscriber and can be diagnosed. Fuel pressure specification is by the ME-SFI [ME] control unit to the fuel pump control unit.
- The signal from the fuel pressure sensor is read in by the fuel pump control unit.
- Fuel system pressure constant at about 3.8 bar. For a "hot start" the fuel system pressure is increased to about 5 to 5.5 bar.
- Camshaft Hall sensor, left cylinder bank is no longer needed.
- A stronger fuel pump (about 20 mm longer) is installed
Changes for ME-SFI 2.7.2 from 01.09.2006:
- In order to control the duel pumps the ME-SFI [ME] control unit detects the current fuel pressure via the fuel pressure sensor and sends a PWM signal (pulse width modulated signal) signal representing the current fuel requirements to the fuel pump control unit. This evaluates the PWM signal and actuates the Fuel pump. The system pressure is then regulated between 4 and 5.5 bar.
- Fuel tank has a pressure relief valve (about 5.2 bar).
- Camshaft Hall sensor, left cylinder bank is no longer needed.

To avoid damage to control unit connect and disconnect the two connectors on control unit only when ignition is switched off.
Terminal 1 of ignition coils must not be short-circuited to GND, e.g. as anti-theft protection.
Install only original ignition system components.
Do not operate ignition system at starting speed unless all of the ignition cables are connected.
No tests such as holding ignition cable 4 at a distance to GND, unplugging a spark plug connector or pulling cable 4 out of the ignition coils, may be performed at starting speed or when the engine is running.
Every high voltage circuit must be loaded with at least 2 kΩ (spark plug connector).
If it is necessary to test the ignition spark when providing roadside assistance, this must only be done with a spark plug at a cylinder ignition cable. Ensure that the spark plug has good contact to ground.
Before working at cranking speed, e.g. checking compression pressure, switch off ignition and disconnect connector "2" from control unit.

Engine 120 has two fuel injection and ignition systems.

Use of testers

Only connect and disconnect secondary measuring sensor to corresponding ignition cables when vertical engine and ignition are switched off.
If the shot-circuit protection is operated (cylinder comparison) and the engine stays upright, it is not possible to conduct the test with this test instrument.
Do not connect test lamp to ignition coil terminals 1 and 15.

Engine 137, 275, 285

Engine 137, 275, 285 with ignition system ECI

It is not possible to test the ignition sparks for example during a roadside assistance on this ignition system.

It is only possible to determine faults in the ignition system through read out of diagnostic trouble code memory by means of STAR DIAGNOSIS.

The separation of electrical connectors at components of ignition system can only take place after switching off the ignition.

To avoid damage, the ignition must not be switched on without ground supply at power supply unit ECI (N91). A sufficient ground supply can only be assured, if the power supply unit ECI (N91) is bolted to the intake manifold (1).

	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	Following two successive driving cycles with faults
3	Checking frequency	Continuous
4	Checked signal or status	Transmission of both ion current signals of the ECI ignition module to ME control unit
5	Fault setting conditions
	ECI ignition module	The direct voltage part (offset voltage) for transmission of ion current signals of 3 cylinders each to the ME control unit must be between 0.1 V and 6 V (depending on load and rpm). The voltages are generated in the ECI ignition module. If one ECI ignition modules is missing one of the two offset voltages, the fault will be recognized in ECI ignition module on the left or right.
	ECI power pack	If both offset voltages are missing on an ECI ignition module the fault will recognized as a fault on the ECI power pack in the left or right channel.
6	Check prerequisites	Engine speed between 1000 up to 4000 rpm engine load more than 30 %
7		Check the corresponding ECI ignition module (battery voltage, ground, auxiliary voltage 23 V, voltage 180 V and lines for ion current signal with ground line for discontinuity). If the lines are OK, replace the ECI ignition module. Check ECI power pack (battery voltage, ground, auxiliary voltage 23 V and voltage 180 V on channels). If a voltage is missing although the voltage supply is OK, replace ECI power pack. The engine will not start if there is a fault in both channels. In case of a fault additional misfires which are damaging to the emissions limit or TWC are recognized on the effected cylinders. If one of the 12 lines with the ignition trigger signals between the ME-SFI [ME] control unit and the ECI ignition module is interrupted only misfires effecting the emission limit or which are TWC damaging are recognized on the effected cylinder. To prevent damage to the die-cast housing, only remove and install the ECI ignition modules according to the instructions! Replace sealing on the spark plug connectors at each removal/installation of the ignition module!
