B1206

B1206-PASSENGER AIRBAG INDICATOR CIRCUIT OPEN

For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With the ignition on.

- Set Condition:
If the Occupant Restraint Controller (ORC) cannot detect voltage on the (G104) Passenger Airbag Indicator Driver circuit.

1. VERIFY THAT DTC B1206-PASSENGER AIRBAG INDICATOR CIRCUIT OPEN IS ACTIVE

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read Occupant Restraint Controller (ORC) DTC.

Does the scan tool display active: B1206-PASSENGER AIRBAG INDICATOR CIRCUIT OPEN?

Yes

- Go To 2

No

- Go To 6

2. VERIFY THAT PASSENGER AIRBAG ON/OFF INDICATOR LAMP IS CONNECTED
1. Turn the ignition off.
2. Gain access to the Passenger Airbag On/Off Switch connector.

Is the Passenger Airbag On/Off SWITCH connected to the dash harness?

Yes

- Go To 3

No

- Connect the Passenger Airbag On/Off Switch to the dash harness connector.
- Perform the ORC VERIFICATION TEST Occupant Restraint Controller (ORC) Verification Test.

3. CHECK (201) FUSED IGNITION SWITCH OUTPUT CIRCUIT OPERATION

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 ORC 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 could result in accidental airbag deployment and serious or fatal injury.

2. Connect the Load Tool 8443-25 ORC Adaptor to the ORC connectors.
3. Measure the resistance of the (G104) Passenger Airbag Indicator Driver circuit between the 23 way cavity 6 of the ORC Adaptor and the Passenger Airbag On/Off Switch connector cavity 3.

Is the resistance below 5.0 ohms?

Yes

- Go To 5
- Perform ORC VERIFICATION TEST Occupant Restraint Controller (ORC) Verification Test

No

- Repair the (G104) Passenger Airbag Indicator Driver circuit for an open.
- Perform the ORC VERIFICATION TEST Occupant Restraint Controller (ORC) Verification Test.

5. CHECK PASSENGER AIRBAG ON/OFF SWITCH FOR AN OPEN
1. Reconnect the Passenger Airbag On/Off Switch 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.

2. Measure the voltage of the (G104) Passenger Airbag Indicator Driver circuit between the cavity 6 of the 24 way ORC Adaptor and ground.

Is the voltage above 6.0 volts?

Yes

- Replace the ORC.
- Perform the ORC VERIFICATION TEST Occupant Restraint Controller (ORC) Verification Test.

No

- Replace the open Passenger Airbag On/Off Switch.
- Perform the ORC VERIFICATION TEST Occupant Restraint Controller (ORC) Verification Test.

6. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTC from all Airbag 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. 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.

WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.

8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If only stored codes return, continue the test until the problem area has been isolated.
10. 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 DTC?

Yes

- Perform the appropriate diagnostic procedure.

No

- No problem found at this time. Erase all codes before returning vehicle to customer.
