B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH

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

Theory of Operation
When powered, the Occupant Restraint Controller (ORC) sends a test current to the Squibs. During this test, the Squibs discovered are checked for agreement with the pre-programmed vehicle configuration of components assigned to the module. The ORC still monitors Squib circuits that are unused even though the module is not pre-programmed for those Squibs.
- When Monitored:
The ORC checks for the presence of a device once at every power up during the module initialization process.

- Set Condition:
This DTC sets when the ORC detects the presence of side airbags while the configuration of the module does not reflect side airbags should be present. Once set, this DTC is latched for the entire power cycle.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

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

NOTE: Ensure the battery is fully charged.

NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.

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

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test

2. VERIFY THAT THE VEHICLE IS EQUIPPED WITH OCCUPANT CLASSIFICATION SYSTEM (OCS)
1. Vehicles equipped with a Occupant Classification System (OCS) will have a Passenger Airbag On/Off Indicator Lamp mounted to the dashboard. Verify that the vehicle is equipped with this indicator lamp.
2. With the scan tool, select ECU View and check that the Occupant Classification Module (OCM) is active on the bus.

Is the vehicle equipped with an Occupant Classification System (OCS)?

Yes

- Go To 3

No

- Replace the ORC.
- Perform the RESTRAINTS SYSTEM VERIFICATION TESTRestraints System Verification Test.

3. CHECK ORC PART NUMBER WITH SCAN TOOL
1. 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 4

No

- Replace the ORC.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST Restraints System Verification Test.

4. CHECK THE VIN WITH THE SCAN TOOL
1. With the scan tool, read the VIN.

Is the correct VIN displayed?

Yes

- Replace the ORC.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST Restraints System Verification Test.

No

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