Pinpoint Test AS: The Safety Belt Warning Chime/Belt-Minder Feature Does Not Operate Correctly

Instrumentation, Message Center and Warning Chimes

Pinpoint Test AS: The Safety Belt Warning Chime Does Not Operate Correctly/The Belt-Minder(R) Feature Does Not Operate Correctly

Normal Operation

The Instrument Panel Cluster (IPC) receives the safety belt and Belt-Minder(R) requests from the Restraints Control Module (RCM) over the High Speed Controller Area Network (HS-CAN). The safety belt warning chime sounds for approximately 6 seconds when the driver safety belt is not fastened and the ignition is switched from the OFF or ACC to the RUN mode.

There are 2 Belt-Minder(R) strategies that are used and implemented by the IPC (Instrument Panel Cluster) as commanded by the RCM (Restraints Control Module). The 2 strategies are designed to provide an increased chime tone activity. Belt-Minder(R) A provides 6 one-second sequences for the first minute of the Belt-Minder(R) warning. Belt-Minder(R) B provides 6 one-second sequences of 3 chime tones in rapid succession for the remainder of the Belt-Minder(R) warning.

NOTE: Make sure that the Belt-Minder(R) chime operation is verified with the vehicle moving at least 10 km/h (6 mph).

This pinpoint test is intended to diagnose the following:

- Safety belt warning indication concern

- Belt-Minder(R) deactivated

- Speedometer concern

- IPC (Instrument Panel Cluster)

PINPOINT TEST AS : THE SAFETY BELT WARNING CHIME IS INOPERATIVE/THE BELT-MINDER(R) FEATURE DOES NOT OPERATE CORRECTLY

AS1 CHECK THE KEY-IN-IGNITION WARNING CHIME OPERATION

- Ignition OFF.

- Insert the key into the ignition lock cylinder.

- Open the LH front door and observe the key-in-ignition warning chime operation.

Does the key-in-ignition warning chime operate correctly?

Yes
GO to AS2.

No
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.

AS2 CHECK THE SAFETY BELT WARNING INDICATOR FOR CORRECT OPERATION

- Ignition ON.

- Within one minute, buckle then unbuckle the LH front safety belt.

- With the engine running, verify the safety belt warning indicator illuminates with the safety belt unbuckled and turns off when buckled.

Does the safety belt warning indicator operate correctly?

Yes
GO to AS3.

No
GO to Pinpoint Test Q. Pinpoint Test Q: The Stability/Traction Control Disabled Indicator Is Never/Always On

AS3 CHECK THE SPEEDOMETER OPERATION

- Verify that the speedometer is operating correctly.

Does the speedometer operate correctly?

Yes
GO to AS4.

No
GO to Pinpoint Test E. Pinpoint Test E: The Speedometer Is Inoperative

AS4 CHECK THE BELT-MINDER(R) CONFIGURATION

- Verify that the Belt-Minder(R) is activated or configured on. Refer to Belt-Minder(R) Deactivating/Activating Testing and Inspection to configure without a scan tool.

Is the Belt-Minder(R) activated?

Yes
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.

No
ACTIVATE the Belt-Minder(R). REFER to Belt-Minder(R) Deactivating/Activating Testing and Inspection. TEST the system for normal operation.
