Simplicity can help many savy members improve engine + tranny basic driveability.

Only work on this if you have Xentry or a MB compatible scanner to read your module fault collection.

The issue this solve is not surging the chassis while fastening the MainGND brass nut - We don't want surge!!!

We're going to repurpose an old fashioned jumper cable. We'll use it to momentarily connect MAIN BATT(-) with the ENG GND (-) while dealing with main connections.


BLACK side ONLY - RED remains UNUSED 👍

Again we are only dealing with BLACK/GND/(-) at all time. We are NOT dealing with RED/PWR/(+) stays unused for our purpose.
​​​​
> WARNING:
- This is experimental and may be dangerous
- Don't try this at home...
- Do not contact to Red (+) battery at any time
- This is entry level once you understand a bit
- Do not run engine with any cabling near belt/fan

If you are confused: dismiss yourself from this experimental procedure.
Invisible electric power can become dangerous regardless of voltage.


> POWER DOWN (1_Aux/2_Main):
Chassis is going to loose power in a controlled way without any surge sparks.

1- PRELIMINARIES:
We are going to first install a GND bypass before anything else.

Clamping GND on MAIN BATT(-)


Clamping GND (-) on M276-3.5NA engine aluminum

> At this point main GND is directly connected via our bypass setup...
We can proceed further with disconnections


Removing MAIN BATT GND(-)


Removing the now bypassed unused GND Post... no current: no spark: no problem!

> At this stage Main remains fully connected via bypass only.


2- AUX OUT:
Let's first disconnect the AUX backup power

Trunk AUX disconnect
(10mm wrench or quick disconnect shown here)

> At this stage without AUX, the chassis remains only powered by MAIN.... let's go back at the front near engine strap.

3- MAIN OUT:
Proceed to this step in less than 30seconds after AUX.

Remove GND clamp from engine at once

Now the chassis has lost all power except BATT LIN Sensor...

4- HYUNDAI OUT:

Unplug the Hyundai BATT Module to manually cause batt relearn.

Now take a 15mn break or longer..Refrain from shorting (+) to (-): the whole procedure helps avoid surges - So pls don't create unnecessary surge that undersized capacitors are going to dislike.


> POWER UP (1_Main/2_Aux):
Chassis is going to power up in a controlled way.
We are going to limit production of sparks to one snap.

1- MAIN BYPASS ON

clamp the GND in one quick snap
That's where you're going to get one small current surge to power up all drained sleeping modules.

2- HYUNDAI BACK IN:

Front Batt sensor is now connected back to Rear-SAM LIN in charge of managing the 12.6V Float voltage based on consumer demands.

3- TRUNK AUX BACK ON

AUX is now back on within 30 seconds

4- MAIN GND BACK IN

reinstall MAIN BATT Strap
No current, no spark, no surge!



Fasten the brass nut with hand torque appreciation

5- BYPASS GND REMOVAL

bypass strap comes off
no current, no spark, no surge!

Falks, there you have it. (Car Care Nut)
Nothing less nothing more. (master Tasos)

> AFTERMATH :
There is very little negative side effects to loosing power on this chassis and so much to gain!

reverse gear: mirror tilt: driver door switch
Windows control: driver door switch
Clocks /Radio automatic!!

There is NO AGGEAVATION with...:
COMMAND CODE : not needed
Windows/roof reset : not needed


> IN ADDITION:
This batteries procedure is perfect for...:
-- winter month storage
-- AGM higher voltage charge cycle
-- Wild chassis gone sleepless (CAN-B)
-- Numerous delays in sloppy tranny shifts
-- Clunky engine affected by CAN latencies
-- Removing modules out without power


-- Results may vary according to how fast networking chaos overwhelms CentralGateWay. About twice a month or weekly is a fair amount of time.

-- You will notice a better throttle response temporarily while network chaos is reduced.

-- You should learn to your IC display to show the Hyunday sensor data. That will help you evidence any live chaos brewing.
-- On the road a Key "On/Off/On" cycle will help you quickly reset limp-modes after prolonged drives.

Enjoy your journey with serenity.
