Pinpoint Test AM: 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 or passenger safety belt is not fastened and the ignition is switched from the OFF or ACC to the RUN mode.

The Belt-Minder(R) feature supplements the safety belt warning function and is enabled after the safety belt warning is complete. The Belt-Minder(R) simultaneously sounds the chime and illuminates the safety belt warning lamp in the IPC (Instrument Panel Cluster) once the vehicle speed has exceeded 9.7 km/h (6 mph), and remains active for 5 minutes from the time it is started.

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.

The Belt-Minder(R) functions exactly the same for both MyKey(TM) and administrator keys except that when a MyKey(TM) is in use, the driver cannot configure the Belt-Minder(R) off. Once the Belt-Minder(R) is activated, the Belt-Minder(R) continues to chime periodically (without the 5 minute time out) and the audio unit is muted until the driver and passenger safety belts are fastened.

NOTE: Make sure that the Belt-Minder(R) chime operation is verified with the vehicle moving at least 9.7 km/h (6 mph).

This pinpoint test is intended to diagnose the following:

- Safety belt warning indication concern

- Belt-Minder(R) deactivated

- Speedometer concern

- RCM (Restraints Control Module)

- IPC (Instrument Panel Cluster)

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

AM1 CHECK THE KEY-IN-IGNITION WARNING CHIME OPERATION

- Ignition OFF.

- On vehicles without Intelligent Access (IA), insert the key into the ignition lock cylinder.

- On vehicles equipped with IA (Intelligent Access), place the ignition in the ACC mode.

- 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 AM2.

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

AM2 CHECK THE DRIVER AND FRONT PASSENGER SAFETY BELT BUCKLE SWITCHES

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: RCM (Restraints Control Module) PIDs.

- Monitor the RCM (Restraints Control Module) driver safety belt buckle PID (SBLT_D_ST) and the front passenger safety belt buckle PID (SBLT_P_ST) while buckling and unbuckling the driver and RH front passenger safety belts.

Do the PIDs display BUCKLED with the safety belt buckled and UNBUCKLED with the safety belt unbuckled?

Yes
GO to AM3.

No
REFER to Restraints and Safety Systems &/or Air Bag Systems.

AM3 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 AM4.

No
GO to Pinpoint Test Q. Pinpoint Test Q: The Safety Belt Warning Indicator Is Never/Always On

AM4 CHECK THE SPEEDOMETER OPERATION

- Verify that the speedometer is operating correctly.

Does the speedometer operate correctly?

Yes
GO to AM5.

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

AM5 CHECK THE BELT-MINDER(R) CONFIGURATION

NOTE: Verify that an administrator key is used for this test and not a MyKey(TM) programmed key. When a MyKey(TM) programmed key is used, the Belt-Minder(R) is automatically turned on and cannot be disabled (if previously disabled by an administrator, the Belt-Minder(R) remains disabled when an administrator key is used).

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

Is the Belt-Minder(R) activated for the seating position in question?

Yes
INSTALL a new RCM (Restraints Control Module). TEST the system for normal operation.

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