B1C47-1ST ROW PASSENGER RETRACTOR 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 Passenger Seat Belt Retractor Tensioner circuits.

- Set Condition:
The ORC has detected low resistance on the Passenger Seat Belt Retractor 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. Select Active or Stored DTC.

Is the DTC active or stored?

Yes

- Go To 2

No

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

2. CHECK FOR SHORTED PASSENGER SEAT BELT RETRACTOR 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 Retractor Tensioner connector.

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

2. Connect the Load Tool 8443 and Jumper 8443-4 to the Passenger Seat Belt Retractor 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 active ORC DTCs.

Does the scan tool display B1C47-1ST ROW PASSENGER RETRACTOR PRETENSIONER CIRCUIT LOW DTC?

Yes

- Go To 3

No

- Replace the Passenger Seat Belt Retractor Tensioner.
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. . Airbag System Intermittent Condition Test

3. CHECK (R506) PASSENGER SEAT BELT RETRACTOR TENSIONER LINE 1 CIRCUIT AND (R504) PASSENGER SEAT BELT RETRACTOR 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 Load Tool 8443 and Jumper from the Passenger Seat Belt Retractor Tensioner connector.
2. Disconnect the ORC connectors.

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

3. Connect the SRS Load Tool Adapter 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 (R506) Passenger Seat Belt Retractor Tensioner Line 1 circuit between the Passenger Seat Belt Retractor Tensioner connector cavity B and ground.
5. Measure the resistance of the (R504) Passenger Seat Belt Retractor Tensioner Line 2 circuit between the Passenger Seat Belt Retractor Tensioner connector cavity A and ground.

Is the resistance below 10K Ohms on either circuit?

Yes

- Repair the Passenger Seat Belt Retractor Tensioner circuits shorted to ground.
- 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.
