B1C3F-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN







- 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 an open or high 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 Load Tool Kit 8443A, and DVOM are required to perform the following test.

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

Does the scan tool display B1C3F-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN DTC?

Yes

- Go To 2

No

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

2. CHECK FOR OPEN DRIVER SEAT BELT BUCKLE TENSIONER





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 8443A 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 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 ORC DTCs.

Does the scan tool display B1C3F-1ST ROW DRIVER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN 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 FOR AN OPEN





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 8443A and Jumper from the Driver Seat Belt Buckle Tensioner connector.
2. Disconnect the ORC connectors.

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