Circuit/System Testing

WARNING: This page is about a different car, the 2017 Chevrolet Spark. 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.

  • Passenger air bag disable on/off indicator.
  • Passenger air bag disable on/off indicator wiring harness.
  1. Ignition OFF, disconnect the scan tool, disconnect the harness connector at the P14 Passenger Air Bag Disable Indicator, wait 2 min.
  2. Test for less than 10 Ω between the ground circuit terminal 2 and ground.
    • If 10 Ω or greater 
    1. Test for less than 2 Ω in the ground circuit end to end
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  3. Ignition ON, command the Passenger Airbag Off Indictor OFF with a scan tool.
  4. Test for less than 11 V between the control circuit terminal 3 and ground.
    • If 11 V or greater 
    1. Ignition OFF, disconnect the X1 harness connector at the K36 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 K36 inflatable restraint sensing and diagnostic module.
    • If less than 11 V 
  5. Command the Passenger Airbag Off Indictor On with a scan tool.
  6. Test for greater than 4 V between the control circuit terminal 3 and ground.
    • If 4 V or less 
    1. Ignition OFF. Disconnect the X1 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.
    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 4 V 
  7. Command the Passenger Airbag On Indictor Off, with a scan tool.
  8. Test for less than 11 V between the control circuit terminal 1 and ground.
    • If 11 V or greater 
    1. Ignition OFF, disconnect the X1 harness connector at the K36 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 K36 inflatable restraint sensing and diagnostic module.
    • If less than 11 V 
  9. Command the Passenger Airbag On Indictor On, with a scan tool.
  10. Test for greater than 4 V between the control circuit terminal 1 and ground.
    • If 4 V or less 
    1. Ignition OFF, disconnect the X1 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 4 V 
  11. Test or replace the P14 Passenger Air Bag Disable Indicator.
