B1BB7-PASSENGER AIRBAG DISABLE SWITCH CONFIGURATION
For a complete wiring diagram refer to Diagrams/Electrical.
- 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.
Diagnostic Test
1. DETERMINE ACTIVE OR STORED DTC
Turn the ignition on.
Ensure the battery is fully charged.
NOTE: For the purpose of this test, the AECM and ACM modules will be referred to as an ORC.
SELECT ACTIVE or STORED DTC:
ORC - ACTIVE DTC
- Go To 2
ORC - STORED DTC
- Go To 9
2. VERIFY EQUIPMENT
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
Select Restraints, Airbag and then Miscellaneous from the Scan Tool menu.
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 *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
4. VERIFY CIRCUITS
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: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the Passenger Airbag On - OFF Switch connectors.
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.
Connect the Load Tool 8443-25 ORC Adaptor to the ORC connector.
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 *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
No
- Go To 6
6. (R106) PAB MUX SWITCH RETURN CIRCUIT SHORT TO GROUND
Measure the resistance of the (R104) PAB MUX Switch Return circuit between the ORC 8443-25 Adaptor and ground.
Is the resistance below 10K ohms?
Yes
- Repair the (R104) PAB MUX Switch Return circuit short to ground.
- Perform *ORC VERIFICATION TEST - VER 1. 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
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 *ORC VERIFICATION TEST - VER 1. 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.
If there are no possible causes remaining, view repair.
Repair
- Replace the Occupant Restraint Controller.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
9. STORED CODE OR INTERMITTENT CONDITION
With the scan tool, record and erase all DTC from all Airbag System Modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
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 wiring and connectors.
Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
With the scan tool monitor active codes as you work through the following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
If only stored codes return continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
Are any ACTIVE DTC present?
Yes
- Select the appropriate diagnostic procedure.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
