2000 Excurison 7.3L PCM fried?
Excurion just died while driving down a bumpy road. Now has no WTS and I have check all fuses 10 times and swapped relays. Also it has a TW chip that could have slip in and out down the bumpy road YIKES
Tried to hook up a Superchip to read code and will not communicate with the superchip.
I pulled computer and checked the pins 71,95 and it is getting 12 volts.
Theft light blinks real fast.......
Anything i'm missing that I should check?
If the computer is fried do I have to take it to the stealership to reprogram it?
