Disconnect the negative battery cable.
Measure the resistance between ground and the PCI Bus circuit at the Diagnostic
Junction Port tester that previously measured below 100.0 ohms.
Disconnect the module harness connector(s).
NOTE: If the problem occurred on a bus circuit that has more than one
module on the same circuit, observe the ohmmeter while disconnecting
each module connector one at a time.
Is the resistance below 100.0 ohms with the module(s) disconnected?
Yes → Repair the PCI Bus circuit that measured below 100.0 ohms for a
