The body control module was there. It checked good, so started trouble shooting all over, used a one amp load to check supply voltages.I found the voltage at c1-20 dropped to zero when loaded to one amp. Started checking the voltage at the fuse, Opened up the wiring harness going to the computer and found batter acid fumes had gotten in to the heavy duct and was eating the insulation and corroding and eating away the copper wire. This spot was right over the top of the battery. Spliced the wire and was back in business with the car running. And the innova 3100f working showing trouble codes that may also be caused by the wiring.
