Question about 2002 Jeep Grand Cherokee
I have already changed the C.P.S. and the battery, but the truck still will not start. I think it might be electrical because when i turn the key but all the way the gauges usaully move to indicate pressure and voltage, well now they are not moving. They are just laying there they do not even flinch when the truck turns over. Thank you in advanced.
This is a very complex problem. sounds to me like the BUS communication between the modules isnt online. hundreds of things can cause this. such as a unprogrammed PCM, shorted sensors, blown fuses for gateway modules, fault SKIM module, of faulty wiring. it is going to be nearly impossible for the vehicle to be repaired without bringing it to a dealership. the dealer has the capability to program modules and has special tools to monitor signals for module to module communication. i know this beacause i work at a jeep/chrysler/dodge dealership. and im not familiar with the term CPS. but i am assuming that its the powertrain control module. and if that is so it needs to be programmed to the vehicle and the Vin # needs to be transfered over from the SKIM module electronically, VIA the DRB3 scan tool that only dealers have access too. hope this helps
