B1182

B1182 - DRIVER SEAT BELT TENSIONER RESISTANCE TO LOW





- When Monitored: Ignition on. The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Seat Belt Squib circuits.

- Set Condition: The Occupant Restraint Controller (ORC) has detected abnormally low resistance in one or both of the Driver Seat Belt Squib circuits.





Diagnostic Test

1. WITH THE SCAN TOOL, READ DTCs

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

NOTE: Ensure the battery is fully charged.

Turn the ignition on.

With the scan tool, select ACTIVE or STORED DTCs.

Is the DTC ACTIVE?

Yes

- Go to 2

No

- Go to 4

2. WITH THE SCAN TOOL, READ ACTIVE DTCs

WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the Driver Seat Belt Tensioner connector.

NOTE: Check connectors - Clean/repair as necessary.

Connect the appropriate Load Tool to the Driver Seat Belt Tensioner Squib connector.

WARNING: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.

With the scan tool, read the active DTCs.

Does the scan tool display an active Driver Seat Belt Tensioner Squib DTC?

Yes

- Go to 3

No

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

3. CHECK DRIVER SEAT BELT TENSIONER SQUIB LINE 1 CIRCUIT FOR A SHORT TO DRIVER SEAT BELT TENSIONER SQUIB LINE 2 CIRCUIT





Disconnect the 8443 Load Tool from the Driver Seat Belt Tensioner connector.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool ORC Adaptor to the ORC connector.

Measure the resistance between the Driver Seat Belt Tensioner Squib Line 1 circuit and the Driver Seat Belt Tensioner Squib Line 2 circuit at the ORC adaptor.

Is the resistance below 1 ohms?

Yes

- Repair the Driver Seat Belt Tensioner Squib Line 1 circuit for a short to the Driver Seat Belt Tensioner Squib Line 2 circuit.
- Perform AIRBAG 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 take the proper precautions can result in accidental airbag deployment and personal injury or death.

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

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

4. 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 personal injury or death, 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 chafed, 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 personal injury or death, 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
