Diagnostic Fault Information
Circuit/System Description
The passenger air bag ON/OFF indicators are used to notify the driver when the passenger presence system has enabled or disabled the passenger instrument panel air bag. When the ignition is turned ON, the ignition voltage is supplied to the passenger presence module. When the inflatable restraint sensing and diagnostic module (SDM) receives the appropriate serial data message from the passenger presence module the SDM will then provide voltage to the appropriate indicator.
Conditions for Running the DTC
* The Vehicle is in Service mode
* Ignition Voltage is between 9-16 V
Conditions for Setting the DTC
The SDM detects improper voltage on the control circuit of the passenger air bag ON or OFF indicator
Actions Taken When the DTC Sets
Passenger air bag ON and OFF indicators are disabled.
Conditions for Clearing the DTC
The condition for setting the DTC no longer exists.

Circuit/System Verification
Note: The passenger air bag ON and OFF indicators may not operate as expected if there are supplemental inflatable restraint (SIR) DTCs. Repair all SIR DTCs before proceeding with this diagnostic.
1. Ignition ON.
2. With a scan tool command the passenger air bag ON indicator and passenger air bag OFF indicator ON and OFF. The respective indicators should turn ON and OFF as commanded.
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.
* Passenger air bag disable on/off indicator.
* Passenger air bag disable on/off indicator wiring harness.
1. Ignition OFF, disconnect the harness connector at the P14 passenger air bag disable indicator. Test for less than 10 ohm between the ground circuit terminal 4 and ground.
• If 10 ohm or greater
Repair the open/high resistance in the circuit.
• If less than 10 ohm
2. Ignition ON, with a scan tool, command the passenger air bag OFF indictor OFF.
3. Test for less than 11 V between the control circuit terminal 5 and ground.
• If 11 V or greater
1. Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. 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 SDM.
• If less than 11 V
4. With a scan tool, command the passenger air bag OFF indicator ON.
5. Test for greater than 4 V between the control circuit terminal 5 and ground.
• If 4 V or less
1. Ignition OFF. Disconnect the X1 harness connector at the K36 SDM.
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 ohm in each control circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, replace the K36 SDM.
• If greater than 4 V
6. With a scan tool, command the passenger air bag ON indicator OFF.
7. Test for less than 11 V between the control circuit terminal 2 and ground.
• If 11 V or greater
1. Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. 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 SDM.
• If less than 11 V
8. With a scan tool, command the passenger air bag ON indicator ON.
9. Test for greater than 4 V between the control circuit terminal 2 and ground.
• If 4 V or less
1. Ignition OFF. Disconnect the X1 harness connector at the K36 SDM.
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 ohm in each control circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, replace the K36 SDM.
• If greater than 4 V
10. Replace the P14 passenger air bag disable indicator.
