Question about 1997 Jeep Grand Cherokee
Code 55 means end of code message and is normal. Code 42 is related to the ASD (auto shut down) relay that is located in the PDC (power distribution control) box under the hood. it is a black box with a removable top. In this box you will see a series of fuses and relay's. The underside of the cover will help identify which one is the ASD. Replace the ASD (there not a lot of money) and see if this works, it should, If not, there is a larger issue with this circuit.
