2. Record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read ORC DTCs.
  Did the DTC return?
  
  Yes
  - Go To Next Step.
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
ISOLATE AND CHECK THE RELATED SEAT BELT BUCKLE SWITCH CIRCUITS FOR A SHORT TO GROUND
1. The ignition must be off when checking a circuit for continuity to ground.
2. Isolate the circuit(s) by disconnecting the Electronic Control Unit (ECU) and every component harness connector containing the circuit(s) being tested. Note: Use the wiring diagram as a guide to follow the path of the circuit.
3. Connect the negative lead of the DVOM to a known good ground.
4. With the positive lead of the DVOM, probe the circuit(s) being tested at the component harness connector and check for continuity between the circuit(s) and ground.
  WARNING:
  Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
  
  WARNING:
  Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.
  
  CAUTION:
  Probing of the circuit cavities at the Occupant Restraint Controller (ORC) body harness connectors and in-line connectors using test kit 2022900080 for back probing the terminal will prevent vehicle wiring harness connector damage during diagnostic procedures.
  
  NOTE:
  There should be no continuity between ground and the circuit being tested.
  
  Is there continuity between ground and the circuit(s) being tested?
  
  Yes
  - Repair the related Seat Belt Buckle Switch circuit(s) for a short to ground.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To Next Step.
CHECK OPERATION OF THE RELATED SEAT BELT BUCKLE SWITCH
1. Replace the related Seat Belt Buckle Switch in accordance with the Service Information. Refer to BUCKLE, SEAT BELT, REMOVAL AND INSTALLATION .
2. Reconnect the vehicle body harness connector to the Driver Seat Belt Buckle Switch.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.
4. 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.
5. 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.
6. Connect the scan tool to the Data Link Connector - use the most current software available.
7. Use the scan tool and erase the stored codes in all airbag system modules.
8. Turn the Ignition OFF, and wait 15 seconds before turning the Ignition ON.
9. Wait one minute, and read active DTCs and if there are none present read the stored DTCs.
  Did the DTC return?
  
  Yes
  - Go To Next Step.
  No
  - Repair is complete.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all ORC harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. 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.
5. Reconnect all ORC harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. 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.
9. 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.
10. With the scan tool, erase DTCs.
11. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
12. With the scan tool, read ORC DTCs.
  Did the 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. Failure to follow these instructions may result in possible serious or fatal injury.
