B2736-78-LEFT PEDESTRIAN PROTECTION SATELLITE SENSOR ALIGNMENT OR ADJUSTMENT INCORRECT

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

Theory of Operation

If there is only one pedestrian protection satellite sensor seeing high g's repeatedly. This would mean a single sensor alignment, sensor not torqued fitting is loose, or some other component may be vibrating or rattling against the sensor. For the description and location of the sensors Impact Sensor - Description For operation of the sensors Impact Sensor - Operation

- When Monitored:
At startup and then continuously.

- Set Condition:
This code will set when a deployment threshold has been exceeded by one of the three pedestrian protection satellite sensors in the same ignition cycle. Confirmation to deploy from a second pedestrian protection satellite sensor is not received. The current threshold for setting this DTC is 100 occurrences within an ignition cycle. This code can set independently for each sensor. This code will be set for the entire ignition cycle. The Airbag Warning Lamp (AWL) will set for this code.





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

1. VERIFY THE DTC IS ACTIVE

NOTE: This DTC must be active for the results of this test to be valid.

1. Perform any Technical Service Bulletins (TSBs) that may apply.
2. Ignition on, engine not running.
3. Using the scan tool, read and record DTCs.
4. Using the scan tool, erase DTCs.
5. A ORC module reset needs to be done to retest for the active code.
6. Perform the ORC module reset. Access the Diagnostic Procedures menu from the ORC ECU Overview screen on the scan tool to perform this operation.
7. Using the scan tool, read DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- Inspect the front end of the vehicle covering fascia, grille, and looking under vehicle for possible damage. Pay extra attention to the pedestrian protection sensor areas for possible damage.
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.

2. INSPECT THE PEDESTRIAN PROTECTION SATELLITE SENSOR ALIGNMENT, FOR INCORRECT INSTALLATION OR DAMAGE

NOTE: If available, check the vehicle repair history for collision damage. Such as a low speed impact with no system deployment and now there is damage.

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.

1. Turn the ignition off.
2. Inspect the front end of the vehicle covering fascia, grille, and looking under vehicle for possible damage. Pay extra attention to the pedestrian protection sensor areas for possible damage.
3. Inspect the torque of the suspect sensor for a possible loose connection.

Were any problems found?

Yes

- Repair as necessary. Test drive vehicle to recreate road vibration to confirm repair. Reset the ORC module. Perform the ORC module reset. Access the Diagnostic Procedures menu from the ORC ECU Overview screen on the scan tool to perform this operation. Perform this operation if the DTC is stored, Repair as necessary and perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test . If the DTC is still active, replace the ORC. Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

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