B0095-49-RIGHT FRONTAL ACCELERATION SENSOR - INTERNAL ELECTRONIC FAILURE

For a complete wiring diagram, refer to the Wiring Information.





Theory of Operation

The location of this right front impact sensor is in the Right Crush Zone of the engine compartment. Impact Sensor - Description. Impact sensors perform internal self-tests and communicate the sensors status using power supplied by the Occupant Restraint Controller (ORC). The sensor communicates this internal failure message using the sensor signal circuit. If the scan tool shows this DTC has a Stored history of setting then the right front impact sensor is to be replaced.

- When Monitored:
Impact sensors perform the self-test for internal circuitry at power up during the initialization process, and continuously through the ignition cycle every 10 ms.

- Set Condition:
This DTC sets when the ORC receives notification of a self-test failure within the impact sensor. Once set, this DTC is latched for the entire ignition cycle.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

Diagnostic Test

NOTE: If the scan tool shows this DTC has a Stored history of setting then the right front impact sensor is to be replaced.
VERIFY ACTIVE DTC

NOTE: Make sure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read ORC DTCs.

Does the scan tool display an active B0095-49-RIGHT FRONTAL ACCELERATION SENSOR - INTERNAL ELECTRONIC FAILURE DTC or shows a setting history in stored?

Yes

WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the Right Front Impact Sensor. Impact Sensor - Removal.
- Perform the RESTRAINT SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No (Did not set a active or stored DTC B0095-49- RIGHT FRONTAL SENSOR - INTERNAL ELECTRONIC FAILURE)

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.
