B1C2D-RIGHT SIDE SEAT THORAX SQUIB 1 OPEN





For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    With the ignition on.

  • Set Condition:

    The Occupant Restraint Controller (ORC) monitors the resistance of the Right Seat Squib circuits. The ORC will set this DTC if it detects an open or high resistance on the Right Seat Squib circuits.


Possible Causes
  
(R32) RIGHT SEAT SQUIB LINE 1 CIRCUIT OPEN
  
(R34) RIGHT SEAT SQUIB LINE 2 CIRCUIT OPEN
  
RIGHT SEAT SQUIB AIRBAG
  
OCCUPANT RESTRAINT CONTROLLER (ORC)
  



Diagnostic Test

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following test.


Turn the ignition on.

Select ACTIVE or STORED DTC:

ACTIVE DTC


STORED DTC

2. CHECK FOR OPEN SQUIB CIRCUITS IN RIGHT SEAT SQUIB AIRBAG


WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


Disconnect the Right Seat Squib Airbag connector.

WARNING: To avoid personal injury or death, do not place an intact uncoupled Seat Squib Airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed.


NOTE: Check connectors - Clean and repair as necessary.


Connect the 8443 Load Tool and 8443-1 Jumper to the Right Seat Squib Airbag connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.


With the scan tool, read the active ORC DTCs.

Does the scan tool display: B1C2D-RIGHT SIDE SEAT THORAX SQUIB 1 OPEN?

Yes


No

3. CHECK (R32) RIGHT SEAT SQUIB LINE 1 CIRCUIT FOR AN OPEN


WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


Disconnect the 8443 Load Tool and Jumper from the Right Seat Squib Airbag connector.
Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.


Connect the ORC 8443-32-L Adaptor to the ORC connectors.
Measure the resistance of the (R32) Right Seat Squib Line 1 circuit between the Right Seat Squib Airbag connector and the ORC 8443-32-L Adaptor.

Is the resistance below 1.0 ohm?

Yes


No

4. CHECK (R34) RIGHT SEAT SQUIB LINE 2 CIRCUIT FOR AN OPEN



Measure the resistance of the (R34) Right Seat Squib Line 2 circuit between the Right Seat Squib Airbag connector and the ORC 8443-32-L Adaptor.

Is the resistance below 1.0 ohm?

Yes

  • WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and personal injury or death.

    WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

  • Replace the ORC in accordance with Service Information.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.


No
  • Repair the (R34) Right Seat Squib Line 2 circuit for an open or high resistance.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

5. CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.


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

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


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.
Reconnect all disconnected components and harness connectors.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.


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.

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
  • Select the appropriate diagnostic procedure from the Table of Contents in this section.


No
  • No problem found at this time. Erase all codes before returning the vehicle to the customer.
