Passenger Airbag On/Off Switch Signal Circuit

PASSENGER AIRBAG ON/OFF SWITCH SIGNAL CIRCUIT

Passenger Airbag On/Off Switch Signal Circuit:

WHEN MONITORED
With the ignition on. The Occupant Restraint Controller (ORC) monitors the status of the Passenger Airbag On/Off Switch Signal circuit.

SET CONDITION
The DTC will set if a communication fault is detected between the ORC and the Passenger Seat Occupant Simulator.

POSSIBLE CAUSES
- Fused B(+) circuit open
- Passenger airbag on/off switch signal circuit open
- Passenger airbag on/off switch signal circuit short to voltage
- Passenger airbag on/off switch signal circuit short to ground
- Passenger seat occupant simulator
- Occupant restraint controller

DIAGNOSTIC TEST

1. MEASURE FUSED B(+) CIRCUIT VOLTAGE





NOTE:
- Inspect Fuse 2 located in the Underhood Accessory Fuse Block. If the fuse is open, repair the cause of the open first before continuing.
- The Passenger Seat Occupant Simulator is located behind the passenger footwell near the Power Amplifier.
- When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

WARNING: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

Disconnect the Passenger Seat Occupant Simulator harness connector.

NOTE: Check connector - Clean/repair as necessary.

WARNING: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.

Measure the voltage of the Fused B(+) circuit at the Passenger Seat Occupant Simulator harness connector.

Q: Is the voltage above 10 volts?

YES: Go to 2
NO: Repair the Passenger Seat Occupant Simulator Fused B(+) circuit. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

2. MEASURE THE PASSENGER AIRBAG ON/OFF SWITCH SIGNAL CIRCUIT RESISTANCE





WARNING: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

Disconnect the ORC harness connector.

NOTE: Check connector - Clean/repair as necessary.

Measure the resistance of the Passenger Airbag ON/OFF Switch Signal circuit from the ORC harness connector to the Passenger Seat Occupant Simulator harness connector.

Q: Is the resistance below 5.0 ohms?

YES: Go to 3
NO: Repair the Passenger Airbag On/Off Switch Signal circuit for an open. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

3. MEASURE THE PASSENGER AIRBAG ON/OFF SWITCH SIGNAL CIRCUIT RESISTANCE




With the ignition off.
Measure the resistance between ground and the Passenger Airbag On/Off Switch Signal circuit.

Q: Is the resistance below 10K ohms?

YES: Repair the Passenger Airbag On/Off Switch Signal circuit for a short to ground. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.
NO: Go to 4

4. MEASURE THE VOLTAGE OF THE PASSENGER AIRBAG ON/OFF SWITCH SIGNAL CIRCUIT





WARNING: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.

Measure the voltage of the Passenger Airbag On/Off Switch Signal circuit at the Passenger Seat Occupant Simulator harness connector.

Q: Is voltage present?

YES: Repair the Passenger Airbag On/Off Switch Signal circuit for a short to voltage. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.
NO: Go to 5

5. MEASURE THE PASSENGER SEAT OCCUPANT SIMULATOR GROUND CIRCUIT RESISTANCE





WARNING: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

Measure the resistance between ground and the Passenger Seat Occupant Simulator Ground circuit.

Q: Is the resistance below 5.0 ohms?

YES: Replace the Passenger Seat Occupant Simulator. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test
NO: Repair the Passenger Seat Occupant Simulator Ground circuit for an open. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.
