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 Driver Airbag Squib connectors.
  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.
  
  NOTE: Check the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-1 to the Driver Airbag Squib connectors.
  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.
3. With the scan tool, read the active ORC DTCs.
  Does the scan tool display: B1B04-DRIVER AIRBAG SQUIB 2 CIRCUIT LOW?
  
  Yes
  - Go to step 3
  No
  - Replace the Driver Airbag in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

2. Disconnect the Clockspring C4 harness connector.
  NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-19 to the Clockspring C4 harness connector.
  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.
4. With the scan tool, read the active ORC DTCs.
  Does the scan tool display: B1B04-DRIVER AIRBAG SQUIB 2 CIRCUIT LOW?
  
  Yes
  - Go to step 4
  No
  - Replace the Clockspring in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

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 SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-19 from the Clockspring C4 harness connector.
2. Disconnect the ORC connectors.
  NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor 8443-24 to the ORC C2 connector.
4. Measure the resistance of the (R63) Driver Squib 2 Line 1 circuit between ground and the SRS Load Tool Adaptor 8443-24.
5. Measure the resistance of the (R61) Driver Squib 2 Line 2 circuit between ground and the SRS Load Tool Adaptor 8443-24.
  Is the resistance below 10K Ohms for either measurement?
  
  Yes
  - Repair the Driver Squib 2 circuit(s) for a short to ground.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Replace the ORC in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
