Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. With the scan tool, read ORC DTCs and record on the repair order.
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 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
  - 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.
CHECK THE PASSENGER OCCUPANT DETECTOR SIGNAL AND RETURN CIRCUITS
NOTE:
This test is intended to verify the integrity of the ODS signal and return circuits.

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. Disconnect the ORC and the ODS connectors for testing ODS signal and return circuits.
2. Test both circuits for a short to ground, short to power, short together or open condition.
  Were any of the above conditions found?
  
  Yes
  - Repair the sensor circuits in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To 3
CHECK RELATED HARNESS CONNECTIONS
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:
If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect all Occupant Restraint Controller (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).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
5. Connect all Occupant Restraint Controller (ORC) harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Connect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Connect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
10. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Replace and program the Occupant Restraint Controller in accordance with the Service Information. Refer to MODULE, OCCUPANT RESTRAINT, REMOVAL .
  - Perform the VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - The wiring or poor connection problem has been repaired.
  - Perform the Occupant Restraint Controller VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
