B1206
B1206-PASSENGER AIRBAG INDICATOR CIRCUIT OPEN
For a complete wiring diagram refer to Diagrams/Electrical.
- When Monitored:
With the ignition on.
- Set Condition:
If the Occupant Restraint Controller (ORC) cannot detect voltage on the (R104) Passenger Airbag Indicator Driver circuit.
Diagnostic Test
1.VERIFY THAT DTC B1206 PASSENGER AIRBAG INDICATOR CIRCUIT OPEN IS ACTIVE
NOTE: Ensure the battery is fully charged.
NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.
Turn the ignition on.
With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
Does the scan tool display active: B1206 PASSENGER AIRBAG INDICATOR CIRCUIT OPEN?
Yes
- Go To 2
No
- Go To 5
2.VERIFY THAT PASSENGER AIRBAG ON/OFF INDICATOR LAMP IS CONNECTED
Turn the ignition off.
Gain access to the Passenger Airbag On/Off Indicator Lamp connector.
Is the Passenger Airbag On/Off Indicator Lamp connected to the dash harness?
Yes
- Go To 3
No
- Connect the Passenger Airbag On/Off Indicator Lamp to the dash harness.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
3.CHECK (R104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT OPERATION
Disconnect the Passenger Airbag On/Off Indicator Lamp connector.
Connect a Test Light between the (R104) Passenger Airbag Indicator Driver circuit and the (F201) Fused Ignition Switch Output (Run-Start) circuit in the Passenger Airbag On/Off Indicator Lamp connector.
Turn the ignition on.
With the scan tool, read ORC DTCs.
Does the scan tool display active: B1206 PASSENGER AIRBAG INDICATOR CIRCUIT OPEN?
Yes
- Go To 4
No
- Replace the Passenger Airbag On/Off Indicator Lamp.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
4.CHECK (R104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR AN OPEN
WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could 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.
Disconnect the ORC C2 connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ORC Adaptor (8443-25) to the ORC connector.
Measure the resistance of the (R104) Passenger Airbag Indicator Driver circuit between the 23-way cavity 6 of the ORC Adaptor and the Passenger Airbag On/Off Indicator Lamp connector cavity 3.
Is the resistance below 5.0 ohms?
Yes
- Replace the ORC.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
No
- Repair the (R104) Passenger Airbag Indicator Driver circuit for an open.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
5.TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTCs from all Airbag modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
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 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 personal injury or death, turn the ignition on, then reconnect the battery.
With the scan tool, monitor active codes as you work through the following steps.
WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing 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 the active DTC in question.
Does the scan tool display any ACTIVE DTCs?
Yes
- Select appropriate symptom from Symptom List.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
