Service Bulletin File in Section: – Bulletin No.: PI1469 Date: May, 2015 PRELIMINARY INFORMATION Subject: Service Air Bag Message Displayed in Driver Information Center (DIC), DTC B0014, B0021 or B001E Set with Symptom Code :04 or 0D Models: 2014 Chevrolet Silverado 1500 2015 Chevrolet Silverado 2500/3500, Suburban, Tahoe 2014 GMC Sierra 1500 2015 GMC Sierra 2500/3500, Yukon, Yukon XL Attention: Ensure the vehicle is not included In Customer Satisfaction Program 14166 before proceeding with this bulletin. Condition/Concern Some customers may comment on a “Service Air Bag” message displayed in the driver information center (DIC). This may be caused by high resistance in the wiring harness connectors. The SDM interprets the high resistance as a fault. DTCs set are B0014 or B0021 or B001E with symptom bytes :04 or :0D. Recommendation/Instructions Determine which DTC has been set: Either B0014 or B001E (Driver’s side seat only) or B0021 (Passenger side seat only) and install electrical jumper wires following the instructions below: Note: Perform the procedure in this bulletin on either the front driver or passenger seat. The SIAB connectors are located under the seat cushion. On the driver side it is a GREEN connector on the outboard side of the seat; on the passenger side it is a GREY connector on the inboard side 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.

Gain access to the underside of the seat cushion by tilting the seat forward until the seat back rests on the steering wheel or IP. The repair can then be performed from the rear seat area. 8. Proceed to the Passenger Side Seat Procedure below. Driver Side Seat Repair Procedure 3957382 1. On the driver seat, locate the outboard green SIAB harness connector (1) on the underside of the seat cushion. 2. Gently pry the connectors from the seat mat. 3. Carefully remove approximately 76 mm (3 in) of conduit and tape from each side of the connector to gain access to the wires. 3957382 3968004 Note: This connector will have varying numbers of wires depending on the vehicle options. Only cut the specified wires. 4. Cut the OG/L-BU (pin 1) and L-GN/OG (pin 2) wires from the connector. If the vehicle is equipped with RPO AYQ, also cut the VT (pin 3) and BN/WH (pin 4) wires from the connector. 3957359 5. Strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. 3957362 Note: Only use heat shrink tube, P/N 12355010, or an equivalent flexible adhesive-lined/moisture resistant heat shrink tube to perform the repair in this bulletin. 6. Add one approximate 38 mm (1.5 in) section of heat shrink tube (3) to each of the cut wires. Important: .500 mm (20 gauge) wire is recommended as the jumper in order to help maintain the integrity of the splice crimp. 7. Add an approximate 102 mm (4.0 in) length jumper wire (2), obtained locally, to reconnect each set of cut wires. 7.1. Strip off approximately 10 mm (0.40 in) of insulation from each end of the jumper wire. 7.2. Fold over one end of the jumper wire and position it together with the folded over end of one the cut wires. 7.3. Crimp a splice clip (1) over the joined wires using Special Tool J-38125-8, nest F. Verify the crimp quality. 7.4. Fold over the other end of the jumper wire and position it together with the folded end of the remaining wire. 7.5. Crimp a splice clip (1) over the joined wires using Special Tool J-38125-8, nest F. Verify the crimp quality. 8. Repeat step 7 on the remaining cut wire(s). 3957373 Caution: 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-38125-5A Ultra Torch or another butane fueled soldering iron when working on SIR circuits. 9. Solder both crimp and splice clips using the Ultratorch, part number J-38125-5A, or another butane fueled soldering iron. 3957374 10. Center the heat shrink tube over all 2 splices and shrink/seal the heat shrink tube securely over the splice crimp and insulated wires. 3957377 11. Wrap woven polyester electrical tape (PET) or equivalent anti-abrasion tape or electrical tape (1) around the spliced section of both wires. Warning: 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. 12. Wrap yellow electrical tape over the polyester electrical tape or black electrical tape. Caution: Avoid routing the harness along sharp metal edges. Ensure that harness is secured with some slack in the harness to allow the harness to flex or move. 3957388 13. Re-install the driver seat. Refer to Driver or Passenger Seat Removal and Installation in SI. 14. Enable the SIR system. Refer to Disabling and Enabling in SI. 15. Connect the vehicle to scan tool (GDS2) and clear any DTCs. Repair complete. Passenger Side Seat Repair Procedure 3957349 1. On the passenger seat, locate the inboard grey SIAB harness connector (1) on the underside of the seat cushion. 3957351 2. Gently pry the connectors from the seat mat. 3. Carefully remove approximately 76 mm (3 in) of conduit and tape from each side of the connector to gain access to the wires. 3957349 3968005 Note: This connector will have varying numbers of wires depending on the vehicle options. Only cut the specified wires. 4. Cut the OG/GY – L-GN/L-GN (pin 1) and BN/OG – OG/OG (pin 2) wires from the connector. 3957359 5. Strip off approximately 13 mm (1/2 in) of insulation from the wiring ends. 3957362 Note: Only use heat shrink tube, P/N 12355010, or an equivalent flexible adhesive-lined/moisture resistant heat shrink tube to perform the repair in this bulletin. 6. Add one approximate 38 mm (1.5 in) section of heat shrink tube (3) to each of the 2 wires. Important: .500 mm (20 gauge) wire is recommended as the jumper in order to help maintain the integrity of the splice crimp. 7. Add an approximate 102 mm (4.0 in) length jumper wire (2), obtained locally, to reconnect each set of cut wires. 7.1.
