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 undeployed airbag face down on a hard surface, the airbag will propel 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 RESTRAINTS SYSTEM 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 8443-1 from the Driver Airbag Squib connectors.
2. Remove the Steering Control Module from the steering column in accordance with the Service Information.
3. Disconnect the Steering Control Module C1 connector.
  NOTE: Check the connectors - Clean and repair as necessary.
4. With the Steering Control Module C1 Connector attached to the steering column, connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-13 to the Steering Control Module C1 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.
5. 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 RESTRAINTS SYSTEM 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 SRS Load Tool Jumper 8443-13 from the Steering Control Module C1 connector.
2. Disconnect the ORC connectors.
  NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Adapter 8443-24 to the ORC C2 connector.
4. Measure the resistance of the (R63) Driver Squib 2 Line 1 circuit between ground and the Steering Column Module C1 connector.
5. Measure the resistance of the (R61) Driver Squib 2 Line 2 circuit between ground and the Steering Column Module C1 connector.
  Is the resistance below 10K Ohms for either measurement?
  
  Yes
  - Repair the Driver Squib 2 circuits with a resistance below 10K Ohms for a short to ground.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Replace the ORC in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
