  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 DTC.
  Does the scan tool display B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH DTC?
  
  Yes
  - Go To 3
  No
  
  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 Driver Airbag in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to 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 (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-19, 4 Pin Jumper) from the Clockspring C4 connector.
2. Disconnect the ORC connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) to the ORC connectors.
  NOTE:
  The IP Harness is always connected to the right side (C1) of the Adaptor (special tool #8443-32-L, Adapter, SRS Adapter).
  
  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. Measure the voltage of the (R63) Driver Squib 2 Line 1 circuit between the Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) cavity C1-8 and ground.
5. Measure the voltage of the (R61) Driver Squib 2 Line 2 circuit between the Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) cavity C1-7 and ground.
  Is there any voltage present for either measurement?
  
  Yes
  
  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.
  - Repair the Driver Squib 2 circuits with voltage present for a short to battery.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  
  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:
  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 in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECKING STORED OR INTERMITTENT CODES
NOTE:
Diagnose and repair all active codes before diagnosing stored codes. For a complete list of airbag system diagnostic procedures, refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX .
1. With the scan tool, record and erase all Airbag System Module DTC.
  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.
2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and harness 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.
4. With the scan tool, monitor for active codes while performing the following:
  - Wiggle the wiring harness and connectors of the related airbag circuit.
  - Continue the test until either a code becomes active or the problem area is isolated.
5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.
  Are any ACTIVE DTC present?
  
  Yes
  - Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - No problem found at this time. Erase all codes before returning the vehicle to the customer.
