Right Side Impact Sensor Signal Circuit

RIGHT SIDE IMPACT SENSOR SIGNAL CIRCUIT

Right Side Impact Sensor Signal Circuit:

WHEN MONITORED
With the ignition on. The Occupant Restraint Controller (ORC) monitors the status of the Right Side Impact Sensor Signal Circuit.

SET CONDITION
The DTC will set if a circuit failure is detected between the ORC and the Right Side Impact Sensor.

POSSIBLE CAUSES
- Fused ignition switch output circuit open
- Right side impact sensor signal circuit open
- Right side impact sensor signal circuit short
- Right side impact sensor
- Occupant restraint controller

DIAGNOSTIC TEST

1. MEASURE THE RIGHT SIDE IMPACT SENSOR FUSED IGNITION SWITCH OUTPUT 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.
- 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 Right Side Impact Sensor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

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

Measure the voltage of the Fused Ignition Switch Output circuit at the Right Side Impact Sensor harness connector.

Q: Is the voltage above 10 volts?

YES: Go to 2
NO: Repair the Right Side Impact Sensor Fused Ignition Switch Output circuit. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

2. MEASURE THE RIGHT SIDE IMPACT SENSOR SIGNAL CIRCUIT RESISTANCE





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

Disconnect the ORC harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance of the Right Side Impact Sensor Signal circuit from the Right Side Impact Sensor harness connector to the ORC harness connector.

Q: Is the resistance below 1.0 ohm?

YES: Go to 3
NO: Repair the Right Side Impact Sensor 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 RIGHT SIDE IMPACT SENSOR SIGNAL CIRCUIT RESISTANCE




With the ignition off.
Measure the resistance between ground and the Right Side Impact Sensor Signal circuit.

Q: Is the resistance below 10K ohms?

YES: Repair the Right Side Impact Sensor 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 RIGHT SIDE IMPACT SENSOR SIGNAL CIRCUIT





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

Measure the voltage of the Right Side Impact Sensor Signal circuit at the Right Side Impact Sensor harness connector.

Q: Is voltage present?

YES: Repair the Right Side Impact Sensor 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 RIGHT SIDE IMPACT SENSOR GROUND CIRCUIT RESISTANCE





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

Measure the resistance between ground and the Right Side Impact Sensor Ground circuit.

Q: Is the resistance below 1.0 ohm?

YES: Replace the Right Side Impact Sensor. Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test
NO: Repair the open Right Side Impact Sensor Ground circuit. 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.
