Diagnostic Test

IDENTIFYING VEHICLE EQUIPMENT
NOTE: Make sure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read ORC active DTCs.
  Does the scan tool display active DTC: B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW?
  
  Yes
  - Go to step 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
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 DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing .
  No
  - Go to step 3
INSPECT DRIVER SEAT HARNESS WIRES AND CONNECTORS
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. Using the wiring diagram/schematic as a guide, inspect the driver seat harness wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
  Are any of these conditions present?
  
  Yes
  - Replace the driver seat harness in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Go to step 4
VERIFY THAT DRIVER SEAT HARNESS IS ROUTED CORRECTLY
1. Verify that the driver seat harness is routed correctly.
  Is the Driver Seat Harness routed correctly?
  
  Yes
  - Go to step 5
  No
  - Reroute the driver seat harness as necessary.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
CHECK (Z261) DRIVER SEAT POSITION SENSOR GROUND CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (Z261) Driver Seat Position Sensor Ground circuit cavity 1.
2. Measure the resistance between ground and the (R263) Driver Seat Position Sensor Voltage circuit cavity 2.
  Is the resistance below 10k Ohms on either circuit?
  
  Yes
  - Replace the Driver Seat Harness in accordance with the service information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Go to step 6
CHECK (Z261) DRIVER SEAT POSITION SENSOR GROUND CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN

1. Disconnect the ORC connectors.
2. Connect the SRS Load Tool Adapter 8443-24 to the ORC C1 connector.
3. Measure the resistance of the (Z261) Driver Seat Position Sensor Ground circuit between the ORC-C1 connector cavity C1-13 and the Driver Seat Track Position Sensor connector cavity 1.
4. Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between the ORC-C1 connector cavity C1-17 and the Driver Seat Track Position Sensor connector cavity 2.
  Is the resistance of either circuit above 5.0 Ohms?
  
  Yes
  - Replace the Driver Seat Harness in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Replace the Occupant Restraint Controller (ORC ) in accordance with the service information. Refer to Restraints/MODULE, Occupant Restraint Controller - Removal .
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
