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

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

Normal Operation
The instrument cluster 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 lock cylinder is turned from the OFF/LOCK or ACC to the ON or START position.

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 instrument cluster once the vehicle speed has exceeded 5 km/h (3 mph), and remains active for 5 minutes from the time it is started.

There are two Belt-Minder(R) strategies that are used and implemented by the instrument cluster as commanded by the RCM. The two strategies are designed to provide an increased level intensity of the chime. Belt-Minder(R) A provides 6 one-second sequences of 0.5-second on/0.5-second off for the first minute of the Belt-Minder(R) warning. Belt-Minder(R) B provides 6 one-second sequences of 0.2-second on/0.2-second off then 0.3-second on/0.3-second off for the remainder of the Belt-Minder(R) warning.

NOTE: Be sure that the safety belt/Belt-Minder(R) chime operation is verified with the vehicle moving at least 5 km/h (3 mph).

This pinpoint test is intended to diagnose the following:
- Safety belt warning indication concern
- Speedometer concern
- Instrument cluster
