1993 Saturn SC2 Q&A
1993 Saturn SC2 Question: PCM death due to ABS?
Have you ever seen a PCM damaged by ABS or other solenoid in the car. I have a 93 saturn SC2 that blows the 5 volt fuse on PCM B location. Computer won't give any check engine lights assumption is (dead PCM). The ABS brake system is empty due to brake line rust through. I just bought the replacement computer and the instructions say check all solenoids. Do I fix or unplug the ABS before installing the computer? inital problem was will not crank. I have tested the fuel pump it works correctly. Thanks,SC2 - SC2
there are soloniods on the computer side that need to be checked. its a lot more than just replacing the pcm. luckily, you dont need a flash to make your replacement pcm work. they should have provided a wring diagraphm that shows which terminals in the hearness need to be checked with the values needed before installing the pcm. follow the directions carefully and take your time.
