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 .
CHECK THE RELATED CONNECTORS AT THE CONTROLLER AND THE SUSPECT DEVICE
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.
1. Disconnect the Squib connector and the related Occupant Restraint Controller (ORC) connector.
2. Re-seat both connectors insuring CPA latching is secure. Turn the ignition on and re-test for the DTC.
  Did the DTC return?
  
  No
  - Repair the poor connection.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  Yes

CHECK FOR A FAULTY SQUIB
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.
1. Disconnect the affected Squib harness connector and insure connector and terminals are not damaged.
2. Using the Airbag Kit 2022400100 and 2022900080, connect tool to the Squib connector.
  multimedia:A supplement to the article is available.
  
  NOTE:
  Most squib tests will require the 2022401100 2.0 ohm resistor for testing. The 2022403100 3.0 ohm resistor is for simulating the SCCM and Driver squibs together on the body side of the column harness.
3. Turn the ignition on.
4. Clear DTC and note if it returns.
  Did the DTC return?
  
  No
  - Replace the affected Squib in accordance with Service Information. Refer to RETRACTOR, SEAT BELT, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  Yes
  - Go To 4
CHECK THE SQUIB CIRCUITS FOR SHORT TO 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.
1. Disconnect the Squib connector and the related Occupant Restraint Controller (ORC) connector.
  NOTE:
  The following tests will be performed with the controller and device isolated from the related circuits being tested. 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.
2. Check for continuity between ground and both of the Squib circuits at the Squib harness connector.
  Is there continuity between ground and either circuit?
  
  Yes
  - Repair the Squib circuit(s) for a short to ground.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To 5
CHECK THE SQUIB CIRCUITS FOR A SHORT TOGETHER
1. Check for continuity between the Squib circuits at the Squib harness connector.
  Is there continuity between the circuits?
  
  Yes
  - Repair the short between the Squib circuits.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To 6
CHECK THE SQUIB CIRCUITS FOR AN OPEN OR HIGH RESISTANCE
1. Measure the resistance of the Squib circuits from the Squib harness connector to the ORC harness connector.
  Is the resistance below 1.0 Ohm on either circuit?
  
  Yes
  - Go To 7
  No
  - Repair the Squib circuit(s) for an open or high resistance.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK THE SQUIB CIRCUITS FOR A SHORT TO VOLTAGE
1. Reconnect the battery for this test.
2. Measure the voltage between ground and the Squib circuits at the Squib connector.
  Is there any voltage present on either circuit?
  
  Yes
  - Repair the Squib circuit(s) for a short to voltage.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  
  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 CONTROLLER, OCCUPANT RESTRAINT (ORC), REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
