B0097-87-RIGHT SIDE ACCELERATION SENSOR 2 - MISSING MESSAGE
Special Tools:
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The location of the right side impact sensor 2 is in the C-pillar area. 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:
The Occupant Restraint Controller (ORC) continuously communicates with the Right Side Impact Sensor 2 over the sensor signal circuit. The sensor communication and on board diagnostics are powered by the ORC signal.
- Set Condition:
This code will set, if the ORC and the Right Side Impact Sensor 2 do not establish and maintain valid data communications.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.
1.
NOTE: The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.
NOTE: Probing of the circuit cavities at the ORC Module C1-A, C1-B, or C2-A body harness connectors is only to be done with a approved test lead from the Dedicated Test Leads kit 10159, test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures. (10159)
