B1C2F
B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH
For a complete wiring diagram Consult Diagrams/Electrical.
- 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 lap state occurs.
- Set Condition:
If the lamp request by the ORC (On or Off), and the Lamp On by the Instrument Cluster (On or Off), messages do not match, this code will set.
Diagnostic Test
1. CHECK FOR AN ACTIVE DTC B1BB8-SRS WARNING INDICATOR STATUS MISMATCH
NOTE: Ensure the battery is fully charged.
Turn the ignition on, then off, and then on again.
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 5
2. CHECK FOR ACTIVE INSTRUMENT CLUSTER DTCs
With the scan tool, read Instrument Cluster DTCs.
Does the scan tool display and active Instrument Cluster DTCs?
Yes
- Refer to symptom list for problems related to the Instrument Cluster.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
No
- Go To 3
3. CHECK THE ORC AND INSTRUMENT CLUSTER FOR LAMP STATUS
With the scan tool view the Instrument Cluster (CCN) Display.
Cycle the ignition key and observe the Passenger Airbag Indicator Lamp (PADL) Request status (Set/Not Set) during the Instrument Cluster bulb check.
With the scan tool view the ORC Data Display.
Select Indicator Lamp Status from Bussed Inputs and select SRS Indicator Lamp request from the Bussed Outputs.
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
- Go To 4
No
- Replace the Instrument Cluster.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
4. REPLACE THE OCCUPANT RESTRAINT CONTROLLER
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
WARNING: If the airbag control module is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.
If there are no possible causes remaining, view repair.
Repair
- Replace the Occupant Restraint Controller.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
5. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTCs from all Airbag modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
With the scan tool, monitor active codes as you work through the following steps.
WARNING: To avoid serious or fatal injury, maintain a safe distance from all airbags while performing the following steps.
Wiggle the wiring harness and connectors of the related Switch Bank circuit or component.
If only stored codes return, continue the test until the problem area has been isolated.
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
- Select appropriate procedure from Symptom List.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
