B1C3D-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW





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

- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Driver Seat Belt Buckle Tensioner circuits.

- Set Condition:
The ORC has detected low resistance on the Driver Seat Belt Buckle Tensioner circuits.





1. VERIFY ACTIVE DTC

NOTE: Make sure the battery is fully charged.

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

1. With the scan tool, read the ORC DTCs.

Does the scan tool display B1C3D-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW DTC?

Yes

- Go To 2

No

- Perform the AIRBAG SYSTEM INTERMITTENT TEST. . Airbag System Intermittent Condition Test

2. CHECK FOR SHORTED DRIVER SEAT BELT BUCKLE TENSIONER CIRCUIT





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 Driver Seat Belt Buckle Tensioner connector.

NOTE: Check the connectors - Clean and repair as necessary.

2. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-20 to the Driver Seat Belt Buckle Tensioner connector.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. 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 ORC DTCs.

Does the scan tool display B1C3D-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW DTC?

Yes

- Go To 3

No

- Replace the Driver Seat Belt Buckle Tensioner.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

3. CHECK (R55) DRIVER SEAT BELT BUCKLE TENSIONER LINE 1 CIRCUIT AND (R53) DRIVER SEAT BELT TENSIONER 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 SRS Load Tool Kit 8443 and Jumper from the Driver Seat Belt Buckle Tensioner connector.

3. Connect the SRS Load Tool Adapter 8443-32-R to the ORC connector.

NOTE: The IP Harness is always connected to the right side (C1) of the 8443-32-R Adapter.

4. Measure the resistance of the (R55) Driver Seat Belt Buckle Tensioner Line 1 circuit between the Driver Seat Belt Buckle Tensioner connector cavity 1 and ground.
5. Measure the resistance of the (R53) Driver Seat Belt Buckle Tensioner Line 2 circuit between the Driver Seat Belt Buckle Tensioner connector cavity 2 and ground.

Is the resistance below 10K Ohms on either circuit?

Yes

- Repair the shorted to ground Driver Seat Belt Buckle Tensioner circuits.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- 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 ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
