HAZARD fuse 5 powers the multifunction alarm module at all times through CKT 1040 (ORN). The multifunction alarm module is grounded through CKT 150 (BLK) to G201. This module produces audible warning alarms under the following conditions:

The safety belt lamp on the instrument cluster will light and the audible alarm will sound for 5 seconds if the driver's side seat belt is not fastened when the ignition switch is placed in the RUN or START positions. The light will automatically extinguish and the audible alarm will be automatically silenced either by fastening the seatbelt or by waiting5 seconds.

When the driver's side seat belt is fastened, contacts in the seat belt switch open. This opens the ground path to G201 through CKT 238 (BLK/WHT) and CKT 150 (BLK). The mulitfunction alarm then senses that the seat belt is fastened.

When the ignition switch is in the RUN or START positions, voltage is sensed at the multifunction alarm module from GAUGES fuse 4 through CKT 39 (PNK).

If the seat belt is not fastened and the ignition switch is in the RUN or START positions, the alarm conditions are met. However, a timing circuit in the module inhibits the alarm after five seconds if the conditions remain present. If the seat belt is opened after the five second delay, the alarm remains inhibited.

The key-in warning alarm is presented if they key reamins in the ignition switch and the driver's side door is opened. This alarm remains present until the key is removed or the door is shut. The multifunction alarm module senses that the key is in the ignition switch and that the door is open by a ground path through the following components:

For recreational vehicles with the upfitter package, the ground is G200. For all other vehicle, ground is G201. Any open in the ground path will inhibit the alarm.

The lamps-on warning alarm is presented if the headlights or the park lights remain on when the ignition switch is turned off. The alarm reamins present until the lights are turned off or the ignition switch is placed in the RUN or START positions.

With the headlamps or park lights on, voltage is sensed by the multifunction alarm module through the following components:

With the IP dimmer switch adjusted for very dim illumination, the voltage sensed at the multifunction alarm module may be too small to set the logic and enable the alarm. Testing should be done with the IP dimmer switch adjusted for maximum illumination.

With the ignition switch in the RUN or START positions, voltage is sensed by the multifunction alarm module from GAUGES fuse 4 through CKT 39 (PNK). When this voltage is not present, but voltage from the IP dimmer switch is present, the alarm conditions are met.

The overspeed warning alarm is sounded when the vehicle exceeds a speed of 120 km/h. This speed is not adjustable, and is based on a frequency signal sent from the vehicle control module on CKT 389 (DK GRN). This signal is also sent to the instrument cluster for the speedometer/odometer function.
