B1BB7-PASSENGER AIRBAG DISABLE SWITCH CONFIGURATION
For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.
- When Monitored:
When the Occupant Restrain Controller (ORC) is not configured for an ON - OFF switch, the ORC monitors the Passenger Airbag On - Off Switch inputs to determine if a switch is present.
- Set Condition
The code will set, if the ORC detects a Passenger Airbag ON - OFF Switch connected to the Airbag Control Module.
ORC is not configured for an ON - OFF switch, the ORC monitors the Passenger Airbag On - Off Switch inputs to determine if a switch is present.
1. DETERMINE ACTIVE OR STORED DTC
1. Turn the ignition on.
2. Make sure the battery is fully charged.
SELECT ACTIVE or STORED DTC:
ORC - ACTIVE DTC
- Go To 2
ORC - STORED DTC
- Go To 9
2. VERIFY EQUIPMENT
1. Inspect vehicle for a Passenger Airbag ON/OFF Switch located in the center of the instrument panel.
Is this vehicle equipped with a Passenger Airbag On/OFF Switch?
Yes
- Go To 3
No
- Go To 4
3. ORC NOT CONFIGURED FOR PAB ON/OFF SWITCH
1. Select Restraints, Airbag and then Miscellaneous from the scan tool menu.
2. Follow instructions to verify the ORC switch configuration.
Does the scan tool show Configured for PAB OFF Switch?
Yes
- Go To 8
No
- Follow instructions on the scan tool to configured the Occupant Restraint Controller to support the Passenger Airbag Switch ON/OFF Switch.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
4. VERIFY CIRCUITS
1. Inspect vehicle for a Passenger Airbag On - Off Switch wiring at the ORC connector.
NOTE: Some vehicles may have the wiring for an ON/OFF Switch but is not equipped with the switch.
Is this vehicle equipped with a Passenger Airbag On/OFF Switch wiring?
Yes
- Go To 5
No
- Go To 8
5. (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT SHORT
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 Airbag On/OFF Switch connectors.
2. Disconnect the Occupant Restraint Controller connectors.
NOTE: Check connectors - Clean and repair as necessary.
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.
3. Connect the Load Tool ORC Adaptor 8443-25 to the ORC connector.
4. Measure the resistance of the (G104) PAB Indicator Driver circuit between the ORC Adaptor and ground.
Is the resistance below 10K Ohms?
Yes
- Repair the (G104) Passenger Airbag Indicator Driver circuit short to ground.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
No
- Go To 6
6. (R106) PAB MUX SWITCH RETURN CIRCUIT SHORT TO GROUND
1. Measure the resistance of the (R104) PAB MUX Switch Return circuit between the ORC Adaptor 8443-25 and ground.
Is the resistance below 10K Ohms?
Yes
- Repair the (R104) PAB MUX Switch Return circuit short to ground.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
No
- Go To 7
7. (R106) PAB MUX SWITCH SENSE CIRCUIT SHORTED TO (R106) PAB MUX SWITCH RETURN CIRCUIT
1. Measure the resistance between the (R106) PAB MUX Switch Sense circuit and the (R104) PAB MUX Switch Return circuit at the Passenger Airbag On/OFF Switch connector.
Is the resistance below 10K Ohms?
Yes
- Repair the Passenger Airbag MUX Switch circuits shorted together.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
No
- Go To 8
8. ORC, MODULE NOT CONFIGURED FOR PAB OFF SWITCH
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.
Repair
- Replace the ORC.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
9. STORED CODE OR INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTC from all Airbag System Modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
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.
3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness connector.
WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
7. With the scan tool monitor active codes as you work through the following steps.
8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
10. If only stored codes return continue the test until the problem area has been isolated.
11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
Are any ACTIVE DTC present?
Yes
- Perform the appropriate diagnostic procedure. Testing and Inspection.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
