I have read the HC908's and this is what i get on MC1 and MC2 cant be read,my programmer (orange 5) says reset pin high.
If i get a new chip what file do i put in it?or do i have to reset ecu and esl and program MCU with foreign dumps and relearn the ecu and esl?

Got one Vito with exactly the same problem... I've discovered that blowing hot air over the EZS would start the car with no problem even cold mornings. I think one of motorolla mcu needs to be replaced, wonder which one...
