Circuit/System Testing

WARNING: This page is about a different car, the 2017 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, scan tool disconnected, disconnect the F106DA Seat Side Air Bag - Driver Inboard harness connector.
  2. Test for greater than 25 Ω between the control circuit terminals 1 and 2.
    • If 25 Ω or less 
    1. Disconnect the X2 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 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 2 control circuits.
      • If less than infinite resistance, repair the short between the 2 circuits.
      • If infinite resistance, replace the Inflatable Restraint Sensing and Diagnostic Module.
    • If greater than 25 Ω 
  3. Ignition ON.
  4. Test for less than 11 V between each control circuit terminal listed below and ground:
    • Control circuit terminal 1
    • Control circuit terminal 2
    • If 11 V or greater 
    1. Ignition OFF, disconnect the X2 harness connector at the Inflatable Restraint Sensing and Diagnostic Module, ignition ON.
    2. Test for less than 1 V between the 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 
  5. Ignition OFF.
  6. Test for greater than 25 Ω between each control circuit terminal listed below and ground:
    • Control circuit terminal 1
    • Control circuit terminal 2
    • If 25 Ω or less 
    1. Disconnect the X2 harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
    2. Test for infinite resistance between the 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 
  7. Install a 3 A fused jumper wire between the control circuit terminals 1 and 2, ignition ON.
  8. Verify "Deployment Loop 19 Type" Resistance scan tool parameter is less than 2 Ω.
    9. NOTE:

    Deployment Loop 19 Type may have a value of "Not Equipped" and still have a value in the Resistance field. This loop is the Driver Seat Inboard Side Air Bag Deployment loop.

    • If 2 Ω or greater 
    1. Ignition OFF, disconnect the X2 harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
    2. 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 
  10. Ignition OFF, connect the harness connector at the Seat Air Bag, press in the CPA (if equipped) until an audible and/or tactile click is heard.
  11. Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
  12. Verify DTC B001E is not set.
    • If DTC B001E is set 

      Replace the F106DA Seat Side Air Bag - Driver Inboard.

    • If DTC B001E is not set 
  13. All OK.
