Test 1 - 3:

Test 4 - 7:

Test 8 - 9:

Test 10 - 11:

Test 12 - 14:

SYMPTOM
NO PCI LOOPBACK

WHEN MONITORED
With the ignition on and the module transmitting information on the BUS.

SET CONDITION
The code will set immediately if the onboard diagnostic cannot detect the module transmitting information on the BUS.

NOTE: Any Bus Failure will may cause a stored code to set.

POSSIBLE CAUSES
- Checking for voltage at ACM
- Wiring harness intermittent
- ACM, no response from
- Airbag control module - ACM
- Ground circuit open
- Occupant classification module - OCM
- Open PCI BUS circuit at the data link connector (DLC)
- PCI BUS circuit open
- PCI BUS circuit shorted to voltage
- Module short to voltage
- PCI BUS circuit shorted to ground
- OCS - service replacement kit
