Passenger Air Bag Indicator Circuit/System Testing (ALO)

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.
NOTE:

When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected.

  • P14 Passenger Air Bag Indicator.
  • P14 Passenger Air Bag Indicator wiring harness.
  1. Ignition OFF.
  2. Disconnect the harness connector at the P14 Passenger Air Bag Indicator.
  3. Test for less than 5 Ω between the ground circuit terminal 2 and ground.
    • If 5 Ω or greater 
    1. Disconnect the harness connector at the K36 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 K36 inflatable restraint sensing and diagnostic module.
    • If less than 5 Ω 
  4. Ignition ON.
  5. Passenger seat occupied.
  6. Test for less than 11 V between the control circuit terminal 3 and ground.
    • If 11 V or greater 
    1. Ignition OFF.
    2. Disconnect the harness connector at the K36 inflatable restraint sensing and diagnostic module.
    3. Ignition ON.
    4. 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 K36 inflatable restraint sensing and diagnostic module.
    • If less than 11 V 
  7. Passenger seat unoccupied.
  8. Test for greater than 25 Ω between the control circuit terminal 3 and ground.
    • If 25 Ω or less 
    1. Disconnect the harness connector at the K36 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
    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 K36 inflatable restraint sensing and diagnostic module.
    • If greater than 25 Ω 
  9. Passenger seat unoccupied.
  10. Test for less than 11 V between the control circuit terminal 1 and ground.
    • If 11 V or greater 
    1. Ignition OFF.
    2. Disconnect the harness connector at the K36 inflatable restraint sensing and diagnostic module.
    3. Ignition ON.
    4. 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 11 V 
  11. Passenger seat occupied.
  12. Test for greater than 25 Ω between the control circuit terminal 1 and ground.
    • If 25 Ω or less 
    1. Disconnect the harness connector at the K36 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
    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 K36 inflatable restraint sensing and diagnostic module.
    • If greater than 25 Ω 
  13. Replace the P14 Passenger Air Bag Indicator.
