STORED CODE OR INTERMITTENT CONDITION

With the scan tool, record and erase all DTC’s from all Airbag System Modules.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or
contaminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
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 codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

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 active DTC in question.

Are any ACTIVE DTCs present?

Yes

>> Select the appropriate diagnostic procedure from the Table of Contents in this section.

Diagnostic Test

1.

PERFORM OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST

Verify that the passenger seat is empty.

Verify that all of the Seat Weight Sensor mounting screws are torqued to specification. Refer to 23 - BODY/SEATS.

NOTE: Failure to follow the test instructions or aborting the test will cause faults to set when performing
the Occupant Classification Module System Verification Test. To prevent faults due to process errors: Verify
That All Tests Steps That Led You Here Were Performed As Directed; Verify That The Ignition Is In Run; Wait
30 Seconds After Changing The Seat Weight Before Proceeding To Allow The System To Stabilize; Only
Press Scan Tool Buttons When Directed To Do So; & Perform The Occupant Classification Module System
Verification Test To Completion.
With the scan tool in OCM, select More Options, select System Tests, and select Occupant Classification Module
System Verification Test. Run the test by following the instructions displayed on the scan tool. When the test is
complete, proceed as follows.

With the scan tool, read OCM DTCs.

Does the scan tool display any active DTCs?

Yes

>> B1BA8 DTC Returned? Perform the *Diagnosis/Checkout Procedure For Seat Weight Sensors.

Yes

>> But Other DTCs Present? Diagnose and repair the DTCs. Refer to the Table of Contents in this Section
