Well, I was looking at this car as if it had a 4 speed auto where it actually has a 5 speed. The trans ECU is separate from the engine ECU.
The trans ECU has a dry joint on it, if you wiggle the connector you can hear the trans clicking in and out. Have checked all lives and grounds and checked the pins.
The problem I have now is when I try to program the original engine ECU back in I get error code P0602 PCM programing error.
I think I might need the 'as built code'. Can anyone tell me how to obtain these?
Regards
Simon
