This Bulletin has been revised to add the 2013-2014 Model Years and Update Labor Operation information. Please discard Corporate Bulletin Number 08-09-41-002G.

Condition

• Some customers may comment on an intermittent or current AIR BAG indicator or lamp being illuminated on the instrument panel cluster (IPC).

Important: This bulletin only applies to the following DTCs:

• Technicians may observe DTC(s) B0012 04, 0D, 0E; B0013 04, 0D, 0E; B0015 04, 0D, 0E; B0016 04, 0D, 0E; B0019 04, 0D, 0E; B0020 04, 0D, 0E; B0022, B0023 04, 0D, 0E; B0033 04, 0D, 0E; B0040 04, 0D, 0E; B0042 or B0044 set as Current or in History in the sensing and diagnostic module (SDM).

Cause

This condition may be caused by a loose, missing, or damaged connector position assurance (CPA) retainer at a supplemental inflatable restraint (SIR) module electrical connector, or a deployment loop wiring harness electrical connector.

Correction

Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components. Serious injury can occur. Failure to observe the correct procedure could also result in unnecessary SIR system repairs.

1. Perform the Diagnostic System Check-Vehicle.
2. Identify the DTC that is set AND review the DTC Descriptor in the corresponding diagnostic procedure. Refer to Diagnostic Trouble Code (DTC) List-Vehicle in SI.
3. Using the information from the DTC Descriptor, determine the location of the affected electrical connector. Refer to SIR Identification Views and the Master Electrical Component List in SI.
4. Turn OFF the ignition and disable the supplemental inflatable restraint (SIR) system. Refer to SIR Disabling and Enabling in SI.
5. BEFORE removing, INSPECT the CPA retainer at the electrical connector.

Note: The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly.

1. • If the CPA retainer is loose, damaged, or will not seat in the connector, replace it with a new one. Reinstall the CPA correctly by first pushing the connector body in completely, and then pushing the CPA retainer in completely.
   • If the CPA retainer is not loose or damaged and is properly seated, proceed to Step 6.

6. Remove the CPA retainer and disconnect the electrical connector. Inspect the terminals for the following conditions:
   • Corrosion
   • Contamination
   • Terminal tension
   • Damage

Important: The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy circuits. Use the J-38125 SIR Terminal Repair Kit for repairing SIR/SRS terminals and connectors. DO NOT substitute any other terminals for those in the repair kit.

1. • If the terminals are damaged, corrosion is observed, or have poor tension, repair or replace as necessary. Apply dielectric grease, GM P/N 12345579 (in Canada, use P/N 10953481) on the connector pins and terminals when reassembling. Refer to SIR/SRS Wiring Repairs in SI.

Note: The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly.

7. Connect the electrical connector, and install the CPA retainer.
8. Enable the supplemental inflatable restraint (SIR) system. Refer to SIR Disabling and Enabling in SI.
9. Clear the DTC with a scan tool.
10. Verify that the DTC does not reset by performing the Diagnostic Repair Verification in SI.
    • If any DTC resets, then refer to Diagnostic Trouble Code (DTC) List – Vehicle in SI.
