B1B76-RIGHT SIDE SATELLITE ACCELERATION SENSOR 2 INTERNAL

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


Impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the module. The repair of this fault centers on verifying the integrity of the sensor's internal circuitry and software validity.


- When Monitored:
The impact sensor performs a 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


1. CHECK FOR OTHER SENSOR INTERNAL DTC'S
NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTCs.
Is there any other Sensor Internal DTCs present?

Yes


- Inspect the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.


No


- Go To 2


2. CHECK OPERATION OF THE RIGHT SIDE IMPACT SENSOR 2

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

Replace the Right Side Impact Sensor 2.
Reconnect the vehicle body harness to the impact sensor.
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.

Connect the scan tool to the Data Link Connector - use the most current software available.
Use the scan tool and erase the stored codes in all airbag system modules.

NOTE: The ORC Reset Function must be performed after the repair to force the module to retest for this DTC. Access the Miscellaneous Function menu from the ORC ECU Overview screen on the scan tool to perform this operation.

Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
Wait one minute, and read active codes.
Did the active Right Side Impact Sensor 2 DTC return?

Yes

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can 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 the ORC.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.


No
