Circuit/System Testing

NOTE:

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

P14 passenger air bag disable indicator
K36 inflatable restraint sensing and diagnostic module

Ignition OFF.
Disconnect the harness connector at the inflatable restraint I/P module indicator.
Test for greater than 11 V between the ignition circuit terminal 4 and ground.
- If less than 11 V
  Repair the open/high resistance in the circuit
- If greater than 11 V
Connect a test lamp between the ignition circuit terminal 4 and the control circuit terminal 5.
Ignition ON.
Occupy the passenger seat, buckle and unbuckle the passenger seat belt, the test lamp should turn OFF and ON while changing between buckled and unbuckled.
- If the test lamp is always on
1. Disconnect the X2 harness connector at the body control module.
2. Test for infinite resistance between the signal circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance, replace the body control module
- If the test lamp is always off
1. Ignition OFF, disconnect the X2 harness connector at the body control module, ignition ON.
2. Test for less than 1 V between the signal circuit and ground.
  - If 1 V or greater, repair the short to voltage on the circuit.
  - If less than 1 V
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 body control module.
- If test lamp turns on and off while changing between the commanded states
Replace the inflatable restraint I/P module indicator.
