T6 instrument cluster dies, engine sputter/stalls intermittently
hi my 01 T6 instrument cluster dies, engine sputter/stalls intermittently some tmes the car starts and rives fine other times wont fire..i checked the voltage and battery was fine as well as alternator but that was when it was running fine... also put a new fuel pump relay seemed to be fixed for a few minutes. also had the transmission not reading proper location of gear?
going crazy here!!!! |
Any electronic module on the high speed CAN bus can cause this issue.
Most vulnerable is ABS and CEM. Rarely that can be ETM (throttle module) and ECM (engine module) To check ABS first. You need to remove connector and place 120 Om resistance between 10-11 pins (CAN terminator). If the issue stops reproducing you can try to re-solder ABS. It it still exists CEM can be the culprit. You cannot remove it like ABS because it is main vehicle computer. |
Hey thanks for the help I took out the abs module opened it up seemed fine and issues didn't go away so I tightened up the ground and it was loose that ended up being it hope that helps someone else
|
so though it was fixed and walla still acting up!!!! Is there a way to determine wether its the cem or ecu?
|
Engine ECU also can be the culprit if car sometimes stalls (and you cannot start engine without making cold start via disconnecting battery ground cable). That can be dying flash.
Usually if dashboard dies but engine continue working ECM is ok. Unfortunately none of both ECM and CEM are easy to replace by used one working modules. Both of them needs at least solder station to 'marry' with your car. Watch carefully at symptoms what is first and what is second when glitches are reproduced. Any detail can help. |
what do you mean by dying flash?
|
Flash content becomes corrupted.
|
seems like a common problem..did you search on google 1st
|
ya for sure ive searched... a lot. I have removed the abs module and the problem persist, Im a cnc machinist and rather handy this the first time I cant repair a car. going nuts
|
seems disconecting the negative on the battery will temp fix the problem for varied lengths of time I think its the ECM
