Jeep Repair Problems? Ask a Mechanic for Answers ASAP
What do you specifically need the diagram for because there are hundreds of diagrams for this car.
The ASD relay?
Here is the wiring diagram for that circuit:
But if you are having problems with stalling and not starting, and have traced it to the ASD relay not closing, you most likely have a bad crankshaft position sensor.
They go bad all the time on these 4.0L motors and cause this problem.
I hope this helps! Let me know if you have any more questions or need any more diagrams!
The PCM ground the ASD relay (in top diagram), when it gets a reference signal from the crank sensor telling it that the engine is turning.
If the PCM is not grounding the ASD relay, im sure you have a bad crank sensor.
I hope this helps! Let me know if you have any more questions!
If a crank sensor shorts, it can temporarily bring down th PCM bus signals, and those guages are part of those signals, so they are most likely as a result of the crank sensor.
You are welcome,
Let me know if you have any more questions!
