B1BA5

B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

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 preprogrammed vehicle configuration of components assigned to the module. The ORC still monitors Squib circuits that are unused even though the module is not preprogrammed 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.


Diagnostic Test


1. VERIFY THAT DTC B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH IS ACTIVE
NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTCs.
Does the scan tool display active: B1BA5-AIRBAG SQUIB CONFIGURATION MISMATCH?

Yes


- Go To 2


No


- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.Restraints System Intermittent Test.


2. CHECK ORC AND VEHICLE CONFIGURATION
With the scan tool, check the ORC and Vehicle Configuration.
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


- Repair the unused Squib circuit.
- Perform the *ORC VERIFICATION TEST-VER 1. Verification Tests


No


- Replace the ORC.
- Perform the *ORC VERIFICATION TEST-VER 1. Verification Tests
