Possible causes B1BA5 code:
- Totally Integrated Power Module (TIPM)
- OCccupant Restraint Controller (ORC)

Diagnostic test B1BA5 code


Make sure the battery is fully charged. Turn the ignition on, with the scan tool read ORC DTC

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

Yes, go to step 2.
No, go to step 5.

Step 2. Check for active TIPM DTC

Verify that the vehicle is equipped with a Occupant Restraint Controller system (OCS). With the scan tool, read the active TIPM DTC.

Is active TIPM DTC present?

Yes, diagnose and repair the active TIPM DTC.
No, go to step 3.

Step 3. Check ORC part number with scan tool

With the scan tool, select ECU view, select ORC, select ECU details and read the ORC part number.

Is the part number correct for the vehicle?

Yes, go to step 4.
No, Turn the igition off, disconnect the 12 volt battery and wait two minutes before preceeding. Failure to follow these instructions may result in possible serious or fatal injury. If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced.

Yes, turn the ignition off, disconnect the 12 volt battery and wait two minutes before proceeding. If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Replace the ORC.

No, replace or reprogram the Totally Integrated Power Module.

Step 5. Test for intermittent condition

With the scan tool record and erase all DTC from all airbag modules. If any active codes are present they must be resolved before diagnosing and stored codes.
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 check may assist you in identifying a possible intermittent problem. Reconnect any disconnected components and harness connector.
With the scan tool monitor active codes as you work through the following steps. Wiggle the wiring harness and connectors of the related airbag 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 DTC?

Yes, refer to DTC based diagnostics and perform the appropriate diagnostic procedure.
No, no problem found at this time. Erase all codes before returning vehicle to customer.
