B1B91-DRIVER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


When powered, the Occupant Restraint Controller (ORC) sends a test current to the seat track position sensors. During this test, the sensors discovered are checked for agreement with the preprogrammed configuration of components assigned to the module.


- When Monitored:
The ORC checks for the presence of seat track position circuits once during the initialization process.

- Set Condition:
This DTC sets when the ORC detects the presence of a seat track position sensor circuit while the configuration of the module does not reflect a seat track position sensor should be present. Once set, this DTC is latched for the entire power cycle and requires the module to be re-initialized to set code.







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


Diagnostic Test


1. DETERMINE ACTIVE OR STORED DTC
NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTC's.
Is the DTC active or stored?

ORC - ACTIVE DTC


- Go To 2


ORC - STORED DTC


- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.Restraints System Intermittent Test.


2. CHECK UNUSED SEAT TRACK POSITION SENSOR CIRCUITS SHORT TO VOLTAGE, SHORT TO GROUND OR SHORT TOGETHER
Check any unused Seat Track Position Sensor circuits for possible short to voltage.
Check any unused Seat Track Position Sensor circuits for possible short to ground.
Check any unused Seat Track Position Sensor circuits for possible short together.
Are any of the unused Seat Track Position circuits shorted?

ORC - ACTIVE DTC


- Repair any unused Seat Track Position Sensor circuits that are shorted.
- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.Restraints System Intermittent Test.


ORC - STORED DTC

NOTE: Ensure the part number of the replacement module is the correct part number for the vehicle.

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.
