Test E: The Safety Belt/Belt-Minder(R) Warning Chime Is Inoperative

PINPOINT TEST E: THE SAFETY BELT/BELT-MINDER(R) WARNING CHIME IS INOPERATIVE

Normal Operation
The instrument cluster (IC) 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 (IC) 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 2 Belt-Minder(R) strategies that are used and implemented by the instrument cluster (IC) as commanded by the RCM. The 2 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 cycle. 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 cycle.

This pinpoint test is intended to diagnose the following:
- Belt-Minder(R) deactivated
- Safety belt warning indication concern
- Instrument cluster (IC)
