2005 - 2013 Corvette: Service Bulletin: #15643A: Special Coverage - Airbag Light On - (Feb 2, 2017)

This bulletin has been revised to add accessory wiring harness part numbers to the Part Information section, update quantities of other parts required, and amend the Service Procedure to install the accessory wiring harness components. Please discard all copies of bulletin 15643.

Condition

On some 2004 - 2009 model year Cadillac XLR and 2005-2013 model year Chevrolet Corvette vehicles, equipped with power seats, the wire harness connector from the seat side airbag and buckle tensioner to the body has a design interference between the vertical adjust crossbar and the carpet. When the seat is moved forward or back, the connector may be dragged along the carpet, pulling terminals loose or pulling the connector apart. This will cause a diagnostic trouble code to be set and the service airbag light will be illuminated.

Special Coverage Adjustment

This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers will replace the affected harness connectors with accessory wiring harness components. The repairs will be made at no charge to the customer.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after April 21, 2016, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to April 21, 2016, must be submitted to the Service Contract provider.

Vehicles Involved

All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system.

Service Procedure

Customers will be notified of the Special Policy by General Motors (see copy of owner letter included with this bulletin).

Note: There is a diagnostic procedure and a repair procedure in this bulletin.

Diagnostic Procedure

Verify that one or more of the following DTCs are present: B0028, B0029, B0030, B0040, B0041, B0045, B0057, B0058, B0059, B0064, B0065 and B0066

Repair Procedure

Use the following steps to remove existing yellow seat to vehicle connector pair and install the service connectors using splice clips, solder and heat shrink. The harness in the seat and on the vehicle will then be rerouted from the rear of the seat to the front of the seat.

Warning: 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. Remove the four seat mounting nuts from the effected seat. Do not remove the seat from the vehicle. Refer to Driver or Passenger Seat Removal and Installation in SI. It is not necessary to disconnect the seatbelt from the seat.
    2. Move the seat to the center position on the seat track.
    3. Disable the Supplemental Inflatable Restraints (SIR) system. Refer to SIR Disabling and Enabling in SI.

    Caution: Use care to not damage the sill plate or interior trim. Cover the area with a heavy shop cloth, masking tape or similar protective measures.

      1. Using wood blocks or similar material, tilt and support the seat in the vehicle as shown.
        1. Locate the yellow harness connector. Disconnect the seat side connector from the vehicle side connector.

        Note: Before removing the yellow connector from the seat and body harness, note the wire colors of the seat and body harness. Some wire pairs may be a slightly different color. Some wire pairs may have different colors. Ensure the wires are matched BEFORE splicing the wires of the new connector set. Use the cutoff connector as a wire color template. BEFORE removing the connector from the harness, mark or identify wire pairs of similar color using a pen and tape to ensure the correct wires are spliced together.

          1. Remove the connector from the seat cross bar by releasing the metal clip.
          2. Make a list of how the wires relate from the body side harness to the seat harness. It critical that the wire pairs are identified correctly to avoid splicing incorrect wire pairs. THE WIRE COLORS ON THE BODY SIDE HARNESS AND THE SEAT SIDE HARNESS ARE NOT THE SAME.
          3. Using side cutters, cut the yellow connector off of the seat wiring harness.
          4. Strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. Fold the wires.
          5. Add one approximate 38 mm (1.5 in) section of heat shrink tube to each of the four wires (1).
          6. On the seat side service connector, strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. Fold the wires.
          7. Join the four wires in the order documented above.

          Note: Keep the heat shrink tube below the splice when soldering the splice to ensure that the heat shrink is not prematurely shrunk and closed down over the wire or splice area due to the heat from the soldering iron.

          Warning: DO NOT use soldering equipment that is battery or electric powered. These types of soldering irons can induce voltage into the circuit, which may cause inflator module deployment and/or damage to electrical components. Use only the J-38125-5 Ultra Torch or another butane fueled soldering iron when working on SIR circuits.

            1. Solder all four crimp and splice clips using the Ultratorch, part number J-38125-5, or another butane fueled soldering iron.
            2. Center the heat shrink tube over all four splices and shrink/seal the heat shrink tube securely over the splice crimp and insulated wires.
            3. Wrap woven polyester electrical tape (PET) or equivalent anti-abrasion tape around the spliced section of seat harness.
            4. Wrap a section yellow electrical tape over the polyester electrical tape.

            Note: Ensure yellow tape is wrapped around the splice section of the seat wire harness to properly identify supplemental inflatable restraint (SIR) wiring. Failure to properly identify SIR wiring could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

            1. Route the harness to the front of the seat as shown.
            2. Secure the harness to the rear of the seat as shown.
            3. Secure the wire connector and harness to the FRONT seat cross bar using two cable ties.
            4. On the vehicle harness, pull the harness from under the carpet, to the front location as shown.
            5. Measure 300mm (11.8 in) from the connector as shown.
            6. Cut the four body side wires.
            7. Strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. Fold the wires.
            8. Add one approximate 38 mm (1.5 in) section of heat shrink tube to each of the four wires.
            9. On the service connector, strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. Fold the wires.
            10. Join the four wires in the order documented above.
            11. Crimp a splice clip over the joined wires using Special Tool J-38125-8, nest F. Verify the crimp quality. Repeat this crimp process on all four wire connections.
            12. Solder all four crimp and splice clips using the Ultratorch, part number J-38125-5, or another butane fueled soldering iron.
            13. Center the heat shrink tube over all four splices and shrink/seal the heat shrink tube securely over the splice crimp and insulated wires.
            14. Wrap woven polyester electrical tape (PET) or equivalent anti-abrasion tape around the spliced section of the harness.
            15. Wrap a section yellow electrical tape over the polyester electrical tape.
            16. Reinstall the driver and/or passenger front seats. Refer to Driver or Passenger Seat Removal andInstallation in SI.
            17. Connect the seat connector to the body connector.
            18. Using a cable tie, secure the harness to the FRONT seat cross bar.
            19. Enable the Supplemental Inflatable Restraints (SIR) system. Refer to SIR Disabling and Enabling in SI.
            20. Clear any sensing and diagnostic module (SDM) DTCs using a scan tool. Verify that the airbag indicator is NOT displayed on the instrument panel cluster (IPC). If DTCs appear after clearing the SDM, refer to the appropriate diagnostic information in SI.
