Diagnostic Test

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

1) VERIFY THAT DTC B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER IS ACTIVE
NOTE: Ensure the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following test.

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 ORC DTCs.

Does the scan tool display active: B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?

Yes
1. Go To 2).
No
1. Go To 6).
2) CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO (F23) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT

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 personal injury or death.

WARNING: If the Occupant Classification Module (OCM) is dropped at any time, it must be replaced. Failure to take the proper precautions can 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 C1 and C2 connectors.

Disconnect the OCM C1 connector.

Disconnect the Switch Bank connector.

NOTE: Check connectors - Clean and repair as necessary.

Connect the appropriate Load Tool ORC Adaptor (8443-24) to the ORC connectors.

Measure the resistance between the (G104) Passenger Airbag Indicator Driver circuit and the (F23) Fused Ignition Switch Output (Run-Start) circuit in the Switch Bank connector.

Is the resistance below 100.0 ohms?

Yes
1. Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to the (F23) Fused Ignition Switch Output (Run-Start) circuit.
2. Perform the *ORC VERIFICATION TEST - VER 1 .
No
1. Go To 3).
3) CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO VOLTAGE

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

Measure the voltage of the (G104) Passenger Airbag Indicator Driver circuit.

Is there any voltage present?

Yes
1. Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to voltage.
2. Perform the *ORC VERIFICATION TEST - VER 1 .
No
1. Go To 4).
4) CHECK FOR ACTIVE DTC B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Remove the Load Tool ORC Adaptor from the ORC connectors.

Reconnect the ORC C1 and C2 connectors.

Reconnect the OCM C1 connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

With the scan tool, erase ORC DTCs.

Turn the ignition off, wait 10 seconds, and then turn the ignition on.

With the scan tool, read ORC DTCs.

Does the scan tool display active: B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?

Yes
1. Go To 5).
No
1. Replace the Switch Bank in accordance with the Service Information.
2. Perform the *ORC VERIFICATION TEST - VER 1 .
5) REPLACE THE ORC
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

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 personal injury or death.

Repair
1. Replace the ORC in accordance with the service information.
2. Perform the *ORC VERIFICATION TEST - VER 1 .
6) 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
1. Select the appropriate diagnostic procedure from the DIAGNOSTIC CODE INDEX .
No
1. No problem found at this time. Erase all codes before returning vehicle to customer.
