B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH

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

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 a squib diagnosed as present when it should not be. Once set, this DTC will go from active to stored upon the squib being diagnosed as not present.





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

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Make sure the battery is fully charged.

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

Is the DTC active or stored?

ORC - ACTIVE DTC

- Go To 2

ORC - STORED DTC

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

2. CHECK ORC AND VEHICLE CONFIGURATION
1. With the scan tool, check the ORC and Vehicle Configuration.
2. With the scan tool, check for resistance present on one unused Squib component and not the other.

Is there resistance present on any one unused squib component and not the 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.

- Repair the unused Squib circuit.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- NOTE: Make sure the part number of the replacement module is the correct part number for the vehicle.
WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
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.
- Replace the ORC. Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
