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.
  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.

  Did the DTC return?
  
  Yes
  - Go To 4
  No
  - Replace the affected Squib in accordance with Service Information. Refer to AIR BAG, REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK STEERING COLUMN CONTROL MODULE SQUIB CIRCUITS FOR AN OPEN
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.

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 SCCM body side harness connector and insure connector and terminals are not damaged.
2. Using the Airbag Kit 3.0 ohm resistor, connect tool to the SCCM connector.
3. Turn the ignition on.
4. Clear DTC and note if it returns.
5. Cycle the ignition off and on.
6. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 5
  No
  
  NOTE:
  The clockspring is part of the internals of the Steering Column Control Module (SCCM). The replacement of the SCCM is required to replace the clockspring.
  
  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.
  - Replace the Steering Column Control Module (SCCM) in accordance with the Service Information. Refer to MODULE, STEERING COLUMN CONTROL (SCCM), REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
ISOLATE AND CHECK THE SQUIB CIRCUITS FOR AN OPEN/HIGH RESISTANCE
1. The ignition must be off when checking the continuity of a circuit.
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. Before measuring the resistance of any circuit, first measure the resistance between the two leads of the DVOM.
  NOTE:
  The meter leads can add resistance to the measurement value.
4. Connect one lead of the DVOM to the circuit being tested at the component harness connector.
5. Connect the other lead to the circuit being tested at the ECU harness connector and measure the resistance of the circuit.
  NOTE:
  When probing a circuit at an Electronic Control Unit (ECU) harness connector, always use an appropriate back probing tool to prevent any possible damage to the ECU terminals.
  
  Is the resistance below.5 Ohm on both circuits?
  
  Yes
  - Go To 6
  No
  - Repair the Squib circuit(s) for an open or high resistance.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
