B1182
B1182-DRIVER SEAT BELT PRETENSIONER CIRCUIT RESISTANCE TOO SMALL [ZH]
- When Monitored:
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: Ensure the battery is fully charged.
Turn the ignition on.
With the scan tool, read ORC DTCs.
Does the scan tool display active DTC: B1182- DRIVER SEAT BELT PRETENSIONER CIRCUIT RESISTANCE TOO SMALL [ZH]?
Yes
- Go to 2
No
- Go to 4
2. WITH THE SCAN TOOL, READ ACTIVE DTCs
WARNING: To avoid serious or fatal injury, 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 and appropriate Jumper to the Driver Seat Belt Tensioner Squib connector.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
With the scan tool, read DTCs.
Does the scan tool display an active DTC: B1182- DRIVER SEAT BELT PRETENSIONER CIRCUIT RESISTANCE TOO SMALL [ZH]?
Yes
- Go to 3
No
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
- 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
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 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 serious or fatal injury.
WARNING: To avoid serious or fatal injury, 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 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 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 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
- Diagnose and repair the DTC(s).
No
- No problem found at this time. Erase all codes before returning the vehicle to the customer.
