WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE:
    • When removing the connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:
      • Retractor pretensioner
      • Air bag
      • SDM module
      • Retractor pretensioner wiring harness connector
      • Air bag wiring harness connector
      • SDM wiring harness connector
    • 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. Verify that the appropriate inflator restraint module connector and CPA are engaged.
    • If the above condition is not found, make the appropriate repair.
  2. Ignition OFF, disconnect the harness connector at the appropriate air bag or pretensioner.
  3. With the appropriate load tool adaptor, connect special tool J 38715-A  in place of the air bag or pretensioner. See Special Tools .
  4. Ignition ON, with a scan tool, verify the appropriate DTC is set as current.
    • If the DTC is not set or is set as history, cycle ignition OFF, disconnect the adapter and J 38715-A  , reconnect the harness connector at the air bag or pretensioner, and cycle the ignition ON. See Special Tools . If the DTC resets after reconnecting the air bag or pretensioner, replace the air bag or pretensioner.
  5. Ignition OFF, disconnect special tool J 38715-A  and the adaptor. See Special Tools .
  6. Disconnect the harness connector at the SDM.
  7. Ignition OFF, disconnect the harness connector at the appropriate air bag or pretensioner. Refer to the appropriate air bag or pretensioner replacement procedure.
  8. Ignition ON, test for less than 1 V between the appropriate high control circuit terminal listed below and ground:

    • Driver Seat Belt Retractor Pretensioner terminal B
    • Passenger Seat Belt Retractor Pretensioner terminal B
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the SDM.
  9. Test for less than 1 V between the appropriate low control circuit terminal listed below and ground:
    • Driver Side Seat Air Bag terminal 2(HP2) or B(-HP2)
    • Passenger Instrument Panel Air Bag Stage 1 terminal A2 (with 10 series) or terminal B(without 10 series)
    • Passenger Instrument Panel Air Bag Stage 2 terminal B2
    • Left Roof Rail Air Bag terminal A (regular cab) or terminal 2 (extended cab)
    • Passenger Side Seat Air Bag terminal 2 (HP2) or B (-HP2)
    • Right Roof Rail Air Bag terminal A (regular cab) or terminal 2 (extended cab)
    • Driver Seat Belt Retractor Pretensioner terminal A
    • Passenger Seat Belt Retractor Pretensioner terminal A
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the SDM.
  10. Ignition OFF, test for infinite resistance between the appropriate high control circuit terminal listed below and ground:
  11. Ignition ON, test for less than 1 V between the appropriate high control circuit terminal listed below and ground:
    • Driver Side Seat Air Bag terminal 1 (HP2) or A (-HP2)
    • Passenger Instrument Panel Air Bag Stage 1 terminal A1 (with 10 series) or terminal A (without 10 series)
    • Passenger Instrument Panel Air Bag Stage 2 terminal B1
    • Left Roof Rail Air Bag terminal B (regular cab) or terminal 1 (extended cab)
    • Passenger Side Seat Air Bag terminal 1 (HP2) or A (-HP2)
    • Right Roof Rail Air Bag terminal B (regular cab) or terminal 1 (extended cab)
    • Driver Seat Belt Retractor Pretensioner terminal B
    • Passenger Seat Belt Retractor Pretensioner terminal B
    • If less than the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the SDM.
  12. Test for infinite resistance between the appropriate low control circuit terminal listed below and ground:
    • Driver Side Seat Air Bag terminal 2(HP2) or B(-HP2)
    • Passenger Instrument Panel Air Bag Stage 1 terminal A2 (with 10 series) or terminal B(without 10 series)
    • Passenger Instrument Panel Air Bag Stage 2 terminal B2
    • Left Roof Rail Air Bag terminal A (regular cab) or terminal 2 (extended cab)
    • Passenger Side Seat Air Bag terminal 2 (HP2) or B (-HP2)
    • Right Roof Rail Air Bag terminal A (regular cab) or terminal 2 (extended cab)
    • Driver Seat Belt Retractor Pretensioner terminal A
    • Passenger Seat Belt Retractor Pretensioner terminal A
    • If less than the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the SDM.
  13. Test for less then 1 Ω between the appropriate high control circuit terminals listed below:
    • Driver Side Seat Air Bag terminal 1 (HP2) or A (-HP2) and SDM terminal 13 X2
    • Passenger Instrument Panel Air Bag Stage 1 terminal A1 (with 10 series) or terminal A (without 10 series) and SDM terminal 5 X1
    • Passenger Instrument Panel Air Bag Stage 2 terminal B1 and SDM terminal 8 X1
    • Left Roof Rail Air Bag terminal B (regular cab) or terminal 1 (extended cab) and SDM terminal 17 X2

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
