B1B75-RIGHT SIDE SATELLITE ACCELERATION SENSOR 1 INTERNAL





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

Theory of Operation

The impact sensors perform their own self-test using power supplied by the Occupant Restraint Controller (ORC) then communicates this status back to the ORC with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC and the sensor.

- When Monitored:
With the ignition on, the Right Side Impact Sensor 1 is equipped with on-board diagnostics to monitor to sensor's internal circuits. If a problem is identified, the sensor sends the Right Side Impact Sensor 1 internal message to the ORC.

- Set Condition:
This Diagnostic Trouble Code (DTC) will sets if the ORC receives an internal DTC from the Right Side Impact Sensor 1.





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

1. DETERMINE ACTIVE OR STORED FAULT CODE

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 active DTC B1B75-RIGHT SIDE SATELLITE ACCELERATION SENSOR 1 INTERNAL DTC?

Yes

- Go To 2

No

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

2. VERIFY OPERATION OF THE RIGHT SIDE IMPACT SENSOR

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. Replace the Right Side Impact Sensor 1.
2. Reconnect the vehicle wire harness connector to the sensor.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components, except the Battery.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. Failure to follow these instructions may result in possible serious or fatal injury.

4. With the scan tool, erase the stored DTCs in all airbag system modules.
5. Turn the ignition Off, and wait 15 seconds before turning the ignition On.
6. Wait one minute.
7. With the scan tool, read the ORC DTCs.

Did the active DTC B1B75-RIGHT SIDE SATELLITE ACCELERATION SENSOR 1 INTERNAL DTC return?

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.

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the ORC.
- Perform the RESTRAINT SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Repair is complete.
