B1C2F

B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH

For a complete wiring diagram Refer to the Wiring Information.

- When Monitored:
After the Switch Bank bulb check is completed, the ORC compares the lamp request by the ORC (Set/Not Set) and the (Set/Not Set) request by the Instrument Cluster Can bus messages. Each message is transmitted one time per second or when a change in the lamp state occurs.

- Set Condition:
If the lamp request by the Occupant Restraint Controller (ORC) (On or Off), and the Lamp On by the Instrument Cluster (On or Off), messages do not match, this code will set.





1. CHECK FOR AN ACTIVE DTC B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on, then off, and then on again.
2. With the scan tool, read Occupant Restraint Controller (ORC) DTCs.

Does the scan tool display active: B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH?

Yes

- Go To 2

No

- Go To 4

2. CHECK FOR ACTIVE INSTRUMENT CLUSTER DTCs
1. With the scan tool, read Instrument Cluster DTCs.

Does the scan tool display and active Instrument Cluster DTCs?

Yes

- Diagnose and repair the DTC's.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Go To 3

3. CHECK THE ORC AND INSTRUMENT CLUSTER FOR LAMP STATUS
1. With the scan tool view the Instrument Cluster (CCN) Display.
2. Cycle the ignition key and observe the Passenger Airbag Indicator Lamp (PADL) Request status (Set/Not Set) during the Instrument Cluster bulb check.
3. With the scan tool view the ORC Data Display.
4. Select Indicator Lamp Status from Bussed Inputs and select SRS Indicator Lamp request from the Bussed Outputs.
5. Cycle the ignition key and observe the Passenger Airbag Indicator Lamp (PADL) Status (Set/Not Set) during bulb check.

Did the Data Display information match each other?

Yes

- WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Replace the Instrument Cluster.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

4. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTCs from all Airbag modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness connector.

WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

7. With the scan tool, monitor active codes as you work through the following steps.

WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.

8. Wiggle the wiring harness and connectors of the related Switch Bank circuit or component.
9. If only stored codes return, continue the test until the problem area has been isolated.
10. In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.

Does the scan tool display any ACTIVE DTCs?

Yes

- Perform the appropriate DTC. Testing and Inspection.
