    3. With the scan tool, read the active ORC DTC.

      Does the scan tool display: B1C2C-RIGHT SIDE SEAT THORAX SQUIB 1 HIGH?

      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.

      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 (R6) Right Seat Squib 1 Line 2 circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-6 and ground.
    5. Measure the voltage of the (R8) Right Seat Squib 1 Line 1 circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-5 and ground.

      Is there any voltage present on either circuit?

      Yes 

      • In accordance with Service Information repair or replace the Right Seat circuits. Right Seat circuits shorted high between the C352 in-line connector (body side) and the SRS Load Tool Adapter (special tool #8443-25, 56 Way ACM Adapter) (32 way) connector.

  5. CHECKING STORED OR INTERMITTENT CODES 
    NOTE:

    Diagnose and repair all active codes before diagnosing stored codes.

    1. With the scan tool, record and erase all Airbag System Module DTCs.
      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.

      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 DTCs present?

      Yes 

      No
