B1C2B-RIGHT SIDE SEAT THORAX SQUIB 1 LOW

Special Tools: Click to display a list of tools used in this procedure

For a complete wiring diagram, refer to the Wiring Information.

Possible Causes

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 low resistance on the Right Seat Squib circuits.

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

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Make sure that the battery is fully charged.

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

1.	Turn the ignition on.

Select ACTIVE or STORED DTC:

ACTIVE DTC

Go To 2

STORED DTC

Go To 4

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

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 Right Seat Squib Airbag connector.

WARNING:

Do not place an intact non-deployed Seat Squib 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 connectors - Clean and repair as necessary.

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

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

Does the scan tool display: B1C2B-RIGHT SIDE SEAT THORAX SQUIB 1 LOW?

Yes

Go To 3

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 Right Seat Squib Airbag in accordance with the Service Information.
Perform the AIRBAG SYSTEM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure).

3. CHECK (R32) RIGHT SEAT SQUIB LINE 1 CIRCUIT AND (R34) RIGHT SEAT SQUIB LINE 2 CIRCUIT FOR A SHORT TO GROUND

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 Load Tool 8443A and Jumper 8443-1 from the Right Seat Squib Airbag connector.

2.	Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

3.	Connect the ORC Adaptor 8443-32-L to the ORC connectors.

4.	Measure the resistance of the (R32) Right Seat Squib Line 1 circuit between ground and the ORC Adaptor 8443-32-L .

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

Is the resistance below 10K Ohms on either circuit?

Yes

Repair the Right Seat Squib circuits with resistance below 10K Oms for a short to ground.
Perform the AIRBAG SYSTEM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure).

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. 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 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure).

4. CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes. (Refer to 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing) for a complete list of airbag system diagnostic procedures.

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 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing) and perform the appropriate diagnostic procedure.

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