B1B2E

B1B2E-1st ROW PASSENGER SEAT BELT PRETENSIONER CIRCUIT OPEN





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
With the ignition on.

- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Passenger Seat Belt Tensioner circuits. The ORC will set this DTC if it detects an open or high resistance on the Passenger Seat Belt Tensioner circuits.





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 OPEN PASSENGER SEAT BELT PRETENSIONER




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

Disconnect the Passenger Seat Belt Pretensioner connector.

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool and 8443-8 Jumper to the Passenger Seat Belt Pretensioner connector.

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

With the scan tool, read the active ORC DTCs.
Does the scan tool display: B1B2E-1st ROW PASSENGER SEAT BELT PRETENSIONER CIRCUIT OPEN?

Yes

- Go to 3

No

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

3. CHECK (R56) PASSENGER SEAT BELT TENSIONER LINE 1 CIRCUIT FOR AN OPEN




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 Passenger Seat Belt Pretensioner connector.
Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

Connect the ORC Adaptor to the ORC C1 connector.
Measure the resistance of the (R56) Passenger Seat Belt Tensioner Line 1 circuit between the Passenger Seat Belt Pretensioner connector and the ORC 8443-25 Adaptor.
Is the resistance below 1.0 ohm?

Yes

- Go to 4

No

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

4. CHECK (R54) PASSENGER SEAT BELT TENSIONER LINE 2 CIRCUIT FOR AN OPEN




Measure the resistance of the (R54) Passenger Seat Belt Tensioner Line 2 circuit between the Passenger Seat Belt Pretensioner connector and the ORC 8443-25 Adaptor.
Is the resistance below 1.0 ohm?

Yes

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

No

- Repair the (R54) Passenger Seat Belt Tensioner Line 2 circuit for an open.
- Perform the *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 chaffed, 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.
