Rule of thumb. Consult a decent auto elec. I was told the ECM module had died by a dodgy A/E, nope, the prick had no clue where the fuses were. (Under a panel behind glove box). I took his word for the dead ecm and had to do 450kms round trip to get one, when it was a 20 cent 20A fuse blown problem. I hope he had a nice Xmas.
