Diagnostic Test

READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR THE DTC TO RETURN
1. With the scan tool, read ORC DTCs and record on the repair order.
2. With the scan tool, run a Vehicle Scan Report or record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Turn the ignition off for at least 10.0 seconds.
5. Turn the ignition on.
6. Using the recorded Environmental Data and the When Monitored Conditions, operate the vehicle in the conditions that set the DTC.
7. 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 .
CHECK THE IMPACT / ACCELERATION SENSOR SIGNAL AND RETURN CIRCUITS FOR A SHORT TO VOLTAGE
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.

NOTE:
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.
1. Turn the ignition off.
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. Turn the ignition on.
4. Using a DVOM, measure the voltage of the circuit being tested at the component harness connector.
  Is there any voltage present on either circuit?
  
  Yes
  - Repair the Impact / Acceleration Sensor circuit(s) for a short to voltage.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to: RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To 3
REPLACE THE IMPACT / ACCELERATION SENSOR AND CHECK DTCS
1. Replace the Impact / Acceleration Sensor in accordance with the Service Information. Refer to: SENSOR, IMPACT, REMOVAL AND INSTALLATION .
2. Operate the vehicle under the conditions that originally set the DTC or use the When Monitored and Set Conditions.
3. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 4
  No
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to: RESTRAINTS SYSTEM VERIFICATION TEST .
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.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
  Repair any conditions that are found.
5. Reconnect all Occupant Restraint Controller (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. With the scan tool, erase DTCs.
9. Using the recorded Vehicle Scan Report, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. 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 follow these instructions may result in possible serious or fatal injury.
  - Replace the Occupant Restraint Controller (ORC) in accordance with Service Information. Refer to: OCCUPANT RESTRAINT CONTROLLER (ORC), REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to: RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to: RESTRAINTS SYSTEM VERIFICATION TEST .
