B1C28-LEFT SIDE SEAT THORAX SQUIB 1 HIGH





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

With the ignition on.

- Set Condition:

The Occupant Restraint Controller (ORC) monitors the voltage on the Left Seat Airbag circuits. If voltage is detected on the Left Seat Airbag circuits the ORC will set this DTC.





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

- Go To 2

STORED DTC

- Go To 5

2. CHECK FOR SHORTED LEFT SEAT AIRBAG SQUIB





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

Disconnect the Left Seat Airbag connector.

WARNING: To avoid serious or fatal injury, do not place an intact undeployed Left 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 Left Seat Airbag connector.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, read the active ORC DTC.

Does the scan tool display : B1C28-LEFT SIDE SEAT THORAX SQUIB 1 HIGH

Yes

- Go To 3

No

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

- Replace the Left Seat Airbag.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

3. CHECK FOR SHORTED LEFT SEAT AIRBAG SQUIB CIRCUITS IN THE SEAT BACK





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

Disconnect the Left Seat Airbag C353 inline connector (under Left Seat).

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool and 8443-20 Jumper to the Left Seat Airbag C353 inline connector (Body Side).

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, read the active ORC DTC.

Does the scan tool display : B1C28-LEFT SIDE SEAT THORAX SQUIB 1 HIGH

Yes

- Go To 4

No

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

- Repair or replace the Left Seat Airbag wiring harness (Side Airbag Jumper). Left Seat Airbag circuits shorted high between the C353 inline connector (Side Airbag Jumper) and the Left Seat Airbag connector.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

4. CHECK FOR SHORTED LEFT SEAT AIRBAG SQUIB CIRCUITS IN THE BODY HARNESS TO THE SEAT





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

Disconnect the 8443 Load Tool and Jumper from the C353 inline connector.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

Connect the ORC 8443-25 Adaptor to the ORC connectors.

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

Measure the voltage of the (R5) Left Seat Squib 1 Line 2 circuit between the 8443-25 cavity C2-16 and ground.

Measure the voltage of the (R7) Left Seat Squib 1 Line 1 circuit between the 8443-25 cavity C2-15 and ground.

Is there any voltage present on either circuit?

Yes

- Repair or replace the Left Seat circuits. Left Seat circuits short to high between the C353 inline connector (body side) and the ORC C2 (32 way) connector.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

No

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

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 serious or fatal injury.

- Replace the ORC.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

5. CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes.

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

WARNING: To avoid serious or fatal injury, 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 serious or fatal injury, 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.

No

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