- VERIFY THAT RELATED SEAT HARNESS IS ROUTED CORRECTLY
- Verify that the related seat harness is routed correctly.
Is the related seat harness routed correctly?
Yes
- Go To 5
No
- Reroute the related seat harness as necessary.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Verify that the related seat harness is routed correctly.
- CHECK THE RELATED SEAT TRACK POSITION SENSOR DATA CIRCUIT AND SEAT TRACK POSITION SENSOR VOLTAGE CIRCUITS FOR A SHORT TO GROUND
- Disconnect the ORC harness connectors.
- Disconnect the related Seat Track Position Sensor connector.
- Measure the resistance of the Seat Track Position Sensor Data circuit between the appropriate terminal of the related Seat Track Position Sensor connector and ground.
- Measure the resistance of the Seat Track Position Sensor Voltage circuit between the appropriate terminal of the related Seat Track Position Sensor connector and ground.
Is there continuity between ground and the circuit(s) being tested?
Yes
NOTE:Do not attempt to repair the Seat Harness. Replace the Seat Harness if the condition inspecting or testing for is present in the Seat Harness.
- Repair or replace the related seat harness circuit(s) for a short to ground.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
No
- Go To 6
- CHECK THE RELATED SEAT TRACK POSITION SENSOR
- Replaced the related Seat Track Position Sensor in accordance with Service Information. Refer to SENSOR, SEAT TRACK POSITION, REMOVAL .
- With the scan tool, erase DTCs.
- Turn the ignition off for 10 seconds.
- Turn the ignition on.
- With the scan tool, read ORC DTCs.
Did the DTC return?
Yes
- Go To 7
No
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Test complete
- CHECK RELATED HARNESS CONNECTIONS
- Disconnect all ORC harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
- Corrosion.
- Other signs of water intrusion.
- Weather seal damage (if equipped).
- Bent terminals.
- Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
- Presence of foreign conductive materials on connector pins and terminals.
- Terminals that have been pushed back into the connector cavity.
- Perform a terminal drag test on each connector terminal to verify proper terminal tension.
Repair any conditions that are found.
- Reconnect all ORC harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
- Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
- Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
- If the vehicle is equipped with the standard key ignition, follow this ignition on warning.WARNING:
Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- If the vehicle is equipped with the keyless ignition, follow this ignition on warning.WARNING:
Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
