9091-RIGHT SIDE IMPACT SENSOR 1 SHORT TO BATTERY





For a complete wiring diagram Consult Diagrams/Electrical.

Theory of Operation

The Occupant Restraint Controller (ORC) supplies power to and communicates continuously with each impact sensor via each sensor's signal circuit. The power supply also enables each sensor's self-diagnostic capabilities. When powered up, the ORC establishes communication with each sensor by sending and receiving acknowledgement messages. The repair of this fault condition centers on confirming wiring, sensor, and module condition.

- When Monitored:
The Occupant Restraint Controller (ORC) supplies power to and communicates continuously with each impact sensor via each sensor's signal circuit.

- Set Condition:
The ORC will set this DTC if the ORC is unable to either establish or maintain communication with the Right Side Impact Sensor 1.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1. VERIFY ACTIVE OR STORED DTC
NOTE: Ensure that the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTC.
SELECT ACTIVE or STORED DTC:

ACTIVE DTC

- Go To 2

STORED DTC

- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST. .

2. VERIFY RIGHT SIDE IMPACT SENSOR 1 SIGNAL CIRCUIT SHORT TO VOLTAGE




WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the ORC connectors.
Disconnect the Right Side Impact Sensor 1 connector.

NOTE: Check connectors - Clean and repair as necessary.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

Measure the voltage of the Right Side Impact Sensor 1 Signal circuit between the Right Side Impact Sensor 1 connector cavity 1 and ground.
Is there any voltage present?

Yes

- Repair the Right Side Impact Sensor 1 Signal circuit for a short to voltage.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

No

- Go To 3

3. VERIFY THE GROUND CIRCUIT




WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Measure the resistance of the Ground circuit between the Right Side Impact Sensor 1 connector cavity 2 and body ground.
Is the resistance below 100k ohms?

Yes

- Repair the open Ground circuit for a short to ground.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

No

- Go To 4

4. REPLACE THE RIGHT SIDE IMPACT SENSOR 1
Replace the Right Side Impact Sensor 1.
Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, erase all DTC in all Restraint System Modules.
Turn the Ignition off, wait 15 seconds, then turn the Ignition on.
Wait one minute before proceeding.
With the scan tool, read active ORC DTC.
Does the scan tool display: 9091-RIGHT SIDE IMPACT SENSOR 1 SHORT TO BATTERY?

Yes

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.

WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

- Replace *ORC.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

No

- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests
