Old thread are the best place to understand something to get things running

Presumably this car does not like .... something

The faster you can figure why the logic is not powering up, the perfectly good parts you'll be tempted to replace with look-alikes.
These parts are coded to your VIN. Used modules are not the first move!

Even swaping relays can be fatal (diode, no-diode, resistor,...).


> No Crank, no ECU, no joy:
Lets stay in the driver seat for now near the OBD DLC Plug. These cars are nearly intelligent. Let's hear what yours has to say:

- 1 - Go look into EIS module Data Stream with ignition On position 1 (less drain)... anything looks alive when you cycle ignition??

- 2 - Go look into driver side F-SAM module: same exercise as above. Toggle things

- 3 - Here at this stage you should have a better understanding of status.

- 4 - Scan the whole car, submit laundry list of faults - Never mind ECU for now. We know car is just not in the mood to go out.

We'll get you hands dirty once we know where to poke. I see schematics in your near future!

 

Thankyou for having the confidence in me to carry out my landry!! The problem is i have no soap!!. Can't wash without the soap kinda thing. I am in a position where i am miles away from a dealer in northern canada and things here are different than in Silicon Valley. I have the i Car soft so i can scan each module individually and then go from there. It iwll happen. just waiting for the wind to go down below 80 mph so i can get back at it.

 

We'll help you out! I really feel for what you guys put up with up their. I watch many of Canadian shows. Yello knife ice roads, Yukon gold mining... Hats off to tough guys.

I don't need to read you anything about not draining battery while playing with your scanner.


Do this:
- 1 - Go look into EIS module Data Stream with ignition On position 1 (less drain)... anything looks alive when you cycle ignition??

- 2 - Go look into driver side F-SAM module: same exercise as above. Toggle things

- 3 - Here at this stage you should have a better understanding of status.

- 4 - Scan the whole car, submit laundry list of faults - Never mind ECU for now. We know car is just not in the mood to go out.

 

OK Calibenzdriver,

The Scanner i have does not produce live stream. It is the I Car Soft MB V2.0. But i was able to do a manual scan of many of the modules.

First off, the ECU has no link. Cannot scan it.
Delected all current codes on all systems and re-scanned.
I now have the following current codes.
Sorry, there is bound to be erroneous info in my pics. In reviewing the pics I do see voltage hovering around 12 V on one module but i do have the charger on and its at least 12.5 back in the trunk. I'm going to look into it a little more.

Also, my clock is not resetting today. i'm stuck in another time zone.


All sam units have no codes
The TCM has no codes
The EIS has no codes
The steering column, instrument cluster and the ecm will not talk.

 

Great! You do have 46 Modules. Your chassis is nearly ok.
ECM is present but is not playing along for some reason.

Before we waste time chassis our tail lets look at history of this car for parts replacement.

I have yo run out but make sure you power up ignition to talk to ECU!!

Get yourself a good cheap scanner such as LAUNCH CReader Elite for Benz.

Do you have any other options instead of purchasing more specialized tools. This will delay me considerably. I have a used car similar to this one. Can I just change the ecm amd scan it to see if I can make continuity to it.

All your engine security parts are paired together. Don't upset that too much as these parts can lockup solid. I recommend against swapping these parts.

If this car has used DONOR PARTS... they are likely your current problem.

Let's try not to overlook the obvious first. If your scanner can not read live data to troubleshoot modules, get one that can. It pays for itself.

Imagine I send you to get firewood with a knife instead of an axe... doesn't matter how hard you try.

I really dig Canadian ingenious bush fixes.
