PCI BUS Communication Failure

Test 1 - 2:

Test 3 - 6:

Test 7 - 8:

SYMPTOM
PCI BUS COMMUNICATION FAILURE

POSSIBLE CAUSES
- Wiring harness intermittent
- Open PCI bus circuit at the data link connector (DLC)
- High voltage on the PCI bus circuits at the BCM connectors
- Module (PCI bus short to voltage)
- PCI bus circuit shorted to voltage
- Low resistance to ground on the PCI bus circuits at the BCM connectors
- Module (PCI bus short to ground)
- PCI bus circuit shorted to ground
