B1B91-DRIVER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L Page 209
Theory of Operation
When powered, the Occupant Restraint Controller (ORC) sends a test current to the seat track position sensors to verify the integrity of the sensor
and wiring. The use of the SRS Load Tool Adapter Tool in the tests below provides a test point in place of the module.
- When Monitored:
With the ignition on the ORC monitors the Driver Seat Track Position Sensors circuits.
- Set Condition:
If the ORC detects current on the Driver Seat Track Position Sensors circuits and the module is not configured for STPS.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. See: Restraints and Safety Systems/Testing and
Inspection/Initial Inspection and Diagnostic Overview/Restraints System Pre-Diagnostic Procedure.
1. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT
CONTROLLER (ORC)
NOTE: Make sure the battery is fully charged.
1. With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
Does the scan tool display any active DTCs relating to internal faults, ignition faults, or battery faults?
Yes
- Diagnose and repair the DTCs. See: .
No
- Go To 2
2. VERIFY THAT B1B91-DRIVER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH IS ACTIVE
1. With the scan tool, erase ORC DTCs.
2. Turn the ignition off, wait 10 seconds and then turn the ignition on.
3. Wait two minutes, and then with the scan tool, read ORC DTCs.
Does the scan tool display active: B1B91-DRIVER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH?
Yes
- Go To 3
No
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
3. VERIFY WIRING
1. Turn the ignition off.
2. Inspect the driver seat wiring for Seat Position Sensors.
Are Seat Position Sensor(s) present?
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 ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
No
- Perform the ORC VERIFICATION TEST. See: Verification Tests/Occupant Restraint Controller (ORC) Verification Test.
