Good day all. I've got a 1996 e50 AMG with the common electrical issue that I've read about a number of times here, that is that none of the interior electrics work. If I disconnect the battery for 15 minutes, they all come back to life for the next start, but once the car is shut off they remain dead until the battery is disconnected.
I'd like to try the old right rear door module swap, my question is, are the modules the same part number across the different models, or am I going to be trying to find an e50 specific module?
and again and again be specific pick a feature the starts and stops and then add to your post[/QUOTE] Sure. The speedometer and cluster go dead. I have swapped the cluster and the locking mechanism on the connector, no change. I have changed the relay block in the engine bay, checked all the fuses, nothing. Right rear window doesn't work, I have swapped out the RR door module, no change, what are the chances both units are faulty? I don't know. When I mention the electrics don't work I'm referring to windows, mirrors, seat control. I have chassis faults on the star scan.
The car has an aftermarket radio in it when I bought it, I have removed this and wired back the original unit. I have also changed the starter motor and rewires the radiator fan. I have looked for loose grounds, no luck, checked the battery and alternator terminals, all good. What I have not done is disconnect each door module one by one or changed the centre console window block. If I'm going to tear apart each door card, the modules are cheap enough that I'd rather have them on hand. I don't know if the e50 has the same part numbers for those modules as other models as there is limited info about e50s online, hence coming here.
first of all forget all your mumbo jumbo---the guy who used the MB HHT tester did not show or print the complete story---all you know is the short test data shows chassis, body and climate control faults then specific modules like traction, EGS EAG and PML no climate control plus he did not right click and provide you with the specific fault codes for modules---otherwise you are blind as to faults because I am sure you havent got the foggiest idea what traction,PML EGS EAG mean
For all your correct parts look here---Mercedes / Car > Mercedes EPC Online > nemigaparts.com
Well I haven't come here because I designed the electrical system of the w210.
There's a lot of owners of early 210s out there experiencing similar problems, so insight on their experience and if the cluster / interior electrics are related in an unexpected way is helpful in narrowing down the issues I'm having on a car that has had some questionable repairs prior to my ownership.
I'll go through the catalogue to cross reference the part numbers on modules etc as required, so good for something then.
Open to others in the community who may be able to shed some light on the issue and if they have successfully resolved them previously.
You have an early version of the CANBUS; Mercedes was releasing multiple versions of a networked interface across multiple models in a short time span. See the attachment to gain some insight at a high level; not a detailed troubleshooting guide.
Like Plutoe said, you need more details. I would hazard a guess most of the failed modules will show something along the lines of "failed network interface". Somewhere, there will be a module that shows "module failed". You have to dig for it. One module will cause a cascade of failures affecting the entire system.
My guess? A failed module is killing the network bus. Where is the junction block? I don't know. What are the network voltages? I don't know. You are going to have to figure that out. The engineers who designed and built this are retired and probably dead. Gonna be difficult to obtain information from them so you need to begin to recreate it. I hope you were able to download a manual for your car that has those values.
See the two following links for suggestions on troubleshooting but be advised the links are for the DAS3 system implemented 03/97. They will not apply to your vehicle but may point you in the right direction. You have a previous version; either DAS2, DAS2a, or DAS2b. Unfortunately, the attached document does not provide voltage values which would be invaluable in troubleshooting your car's network. Be advised, one bad module can and will kill the entire network. Find the module, disconnect it, then deal with the repercussions (will the window ever roll down and up again?) https://mbworld.org/forums/e-class-w...is-repair.html https://mbworld.org/forums/e-class-w...-part-2-a.html
Take lots of notes and photos and post them here so others can learn from your efforts.
