TRINDU
PBB Orphan
100% stock including all the BS emissions. Before I just become a parts monkey, anyone have a direction to go?
Turn the key and no crank. Everything else in the truck works. I can jump the starter wire and the engine spins over but no start. so starter is good. No engine DTCs, I'll add to that later.
I noticed the PRNDL light doesnt come on. Gears all hit the holes just fine. No letters, no outline. I traced wires under the tipm and looms and found no breaks or chafed. The connector for the valve body was clean and no obvious bad pins, wear, corrosion.
I scanned all the modules and came up with:
TIPM - lost comms with ECU/PCM
- starter circuit open (prob from me jumping circuit)
WCM - lost comms with ICM
TCM - P0652 - low voltage (batteries are good and this one comes and goes)
ABS - orginal vin mismatch
- vehicle config missing
- list comms with ecu/pcm
- lost coms with icm
I reset the cluster and disconnected the batteries for 30 minutes and tried again. Same shit.
If I clear all the codes. The WCM, TCM, and TIPM go away until I tried cranking it again by jumper. ABS codes come back immediately.
My main concern is the PRNDL doesnt register, so nothing about the engine will work. Is this a TIPM problem or do I need to drop the VB and replace the module? Everything looks to be adjusted fine. I've dealt with PCM issues in this generation before, theyll let me crank but not start, so I'm ruling that out.
Reflash? TIPM? VB/range selector?
