B1C4E-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN





For a complete wiring diagram, refer to the wiring information Electrical Diagrams.

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

- Set Condition:
The ORC has detected an open or high resistance on the Passenger 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 B1C4E-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN DTC?

Yes

- Go To 2

No

- Perform the AIRBAG SYSTEM INTERMITTENT TEST. .

2. CHECK FOR OPEN PASSENGER 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 Passenger 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 Passenger 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 B1C4E-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT OPEN DTC?

Yes

- Go To 3

No

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

3. CHECK (R272) PASSENGER 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 8443 and Jumper from the Passenger Seat Belt Buckle Tensioner connector.
2. Disconnect the ORC connectors.

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

3. Connect the SRS Load Tool Adaptor 8443-32-R to the ORC connectors.

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

4. Measure the resistance of the (R56) Passenger Seat Belt Buckle Tensioner Line 1 circuit between the Passenger Seat Belt Buckle Tensioner connector cavity 2 and the SRS Load Tool Adaptor 8443-32-R cavity C2-10.

Is the resistance below 1.0 Ohm?

Yes

- Go To 4

No

- Repair the (R56) Passenger Seat Belt Buckle Tensioner Line 1 circuit for and open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

4. CHECK (R274) PASSENGER SEAT BELT BUCKLE TENSIONER LINE 2 CIRCUIT FOR AN OPEN




1. Measure the resistance of the (R54) Passenger Seat Belt Buckle Tensioner Line 2 circuit between the Passenger Seat Belt Buckle Tensioner connector cavity 1 and the SRS Load Tool Adaptor 8443-32-R cavity C2-9.

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 follow these instructions may result in possible serious or fatal injury.

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

No

- Repair the (R54) Passenger Seat Belt Buckle Tensioner Line 2 circuit for and open.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
