B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) checks for Driver Knee Blocker, Curtain Side Airbag, or Thorax (Seat) Airbag components and compares the results against the ORC component configuration.

- Set Condition:
The DTC will be set active, if any Driver Knee Blocker, Curtain Side Airbag, or Thorax (Seat) Airbag components are present and the ORC is not configured for that component.





1. VERIFY THAT DTC B1BA5 AIRBAG SQUIB CONFIGURATION MISMATCH IS ACTIVE

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.

Does the scan tool display active: B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH?

Yes

- Go To 2

No

- Go To 4

2. CHECK ORC PART NUMBER
1. With the scan tool, read the ORC part number.

Is the part number correct for the vehicle?

Yes

- Go To 3

No

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

3. CHECK VIN WITH SCAN TOOL

NOTE: The PCM provides the VIN and the TIPM send the configuration message over the BUS.

1. With the scan tool, read the VIN.

Is the correct VIN displayed?

Yes

- Replace the Totally integrated Power Module (TIPM).
- Perform the TOTALLY INTEGRATED POWER MODULE VERIFICATION TEST.Body Verification Test.
- Perform the AIRBAG SYSTEM VERIFICATION TEST.Airbag System Verification Test.

No

- Replace the Powertrain Control Module (PCM).
- Perform the POWERTRAIN CONTROL MODULE VERIFICATION TEST. Powertrain Verification Test.

- 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 airbag 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 diagnostic procedure. Testing and Inspection.

No
