Circuit/System Testing

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the scan tool.
  2. Disconnect the appropriate harness connector listed below:
    • Seat Belt Anchor Pretensioner
    • Seat Belt Retractor Pretensioner
  3. Wait for 120 seconds.
  4. Test for greater than 25 Ω between the appropriate control circuit terminals listed below:
    • Seat Belt Anchor Pretensioner terminals 1 and 2
    • Seat Belt Retractor Pretensioner terminals A and B
    • If 25 Ω or less 
    1. Disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
      2. NOTE:

      Some connectors may be equipped with shorting bars as a safety component to prevent accidental inflator deployment. When testing on a connector with shorting bars, the shorting bars must be disabled to ensure accurate test results. Insert an appropriate pick from EL-38125-580 and depress the shorting bars above the appropriate terminals. This will lift the shorting bar from the terminal and allow accurate test results. Take care not to damage the connector, shorting bar, or terminal when depressing the shorting bar.

    2. Test for infinite resistance between the two control circuits.
      • If less than infinite resistance, repair the short between the two circuits.
      • If infinite resistance, replace the Inflatable Restraint Sensing and Diagnostic Module.
    • If greater than 25 Ω 
  5. Ignition ON.
  6. Test for less than 11 V between the control circuit terminals listed below and ground:
    • Seat Belt Anchor Pretensioner terminal 1
    • Seat belt Anchor pretensioner terminal 2
    • Seat Belt Retractor Pretensioner terminal A
    • Seat Belt Retractor Pretensioner terminal B
    • If 11 V or greater 
    1. Ignition OFF, disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module, ignition ON.
    2. Test for less than 1 V between each control circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the Inflatable Restraint Sensing and Diagnostic Module.
    • If less than 11 V 
  7. Ignition OFF.
  8. Test for greater than 25 Ω between the control circuit terminals listed below and ground:
    • Seat Belt Anchor Pretensioner terminal 1
    • Seat Belt Anchor Pretensioner terminal 2
    • Seat Belt Retractor Pretensioner terminal A
    • Seat Belt Retractor Pretensioner terminal B
    • If 25 Ω or less 
    1. Disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
    2. Test for infinite resistance between each control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the Inflatable Restraint Sensing and Diagnostic Module.
    • If greater than 25 Ω 
  9. Ignition OFF.
  10. Install a 3 A fused jumper wire between the appropriate control circuit terminals listed below:
    • Seat Belt Anchor Pretensioner terminals 1 and 2
    • Seat Belt Retractor Pretensioner terminals A and B
  11. Ignition ON.
  12. Verify the scan tool Deployment Loop Resistance parameter is less than 2 Ω.
    • If 2 Ω or greater 
    1. Ignition OFF.
    2. Disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
    3. Test for less than 2 Ω in each control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the Inflatable Restraint Sensing and Diagnostic Module.
    • If less than 2 Ω 
  13. Ignition OFF, connect the harness connector at the Seat Belt Anchor Pretensioner or Seat Belt Retractor Pretensioner, press in the CPA (if equipped) until an audible and/or tactile click is heard.
  14. Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
  15. Verify DTC B0015, B001A, B001B, or B0022 is not set.
    • If B0015, B001A, B001B, or B0022 is set 

      Replace the appropriate Seat Belt Anchor Pretensioner or Seat Belt Retractor Pretensioner.

    • If DTC B0015, B001A, B001B, or B0022 is not set 
  16. All OK.
