Very Strange ECU
First up I have a 2005 156 1.9 M-JTD 140
Here's the problem......
I have an ELM cable and PCM Scan (also tried scantool). The engine management light is coming on every time I start the car. When I read the error code the scanning software is saying there is no error code and the MIL status is off ?!?!
Then I rested the MIL anyway and the light goes off on the dash. I can then stop the engine and restart it as often as I like one after another and the engine is fine. If I walk away and leave the car for 15 mins and come back to start it..... Motor Control System Failure. The light is back on and the scantool say NO Error.
Really frustrating... anyone else had this?
Thanks a million in advance.
p.s. Also I notice that the scan tool is not picking up on half the sensors it used to. I can't even see engine RPM or temperatures.... and I used to be able to.
