Audible Warnings Circuit Description Domestic

HAZARD fuse 5 through CKT 1040 (ORN) powers at all times the multi-function alarm module. The multi-function alarm module has ground through CKT 150 (BLK) to ground G201. The multi-function alarm module produces audible warning alarms under the following conditions:

The safety belt lamp on the instrument cluster lights when the ignition switch is in the RUN position or in the START position. The audible alarm sounds for 5 seconds. The safety belt lamp flashes after 15 seconds. The light automatically extinguishes and the audible alarm automatically silences by fastening the seat belt. Fastening the driver's side seat belt opens the contacts in the seat belt switch. This action opens the ground path to ground G201 through CKT 238 (BLK/WHT) and CKT 150 (BLK). The multi-function alarm module senses that the seat belt is fastened. When the ignition switch is in the RUN position or in the START position, the multi-function alarm module senses voltage from GAUGES fuse 4 through CKT 39 (PNK). An unfastened seat belt and the ignition switch in the RUN position or the START position meet the alarm conditions. However, a timing circuit in the module inhibits the alarm after 5 seconds when the conditions remain present. The alarm remains inhibited after the seat belt opens following the 5-second delay.

The key-in warning alarm is present when the key remains in the ignition switch and the driver door opens. The alarm remains present until the removal of the key or the closing of the door. The multi-function alarm module senses that the key is in the ignition switch and the door is open by the ground path to CKT 80 (LT GRN) through the following paths:

For recreational vehicles with upfitter provisions, the ground is G200 and G201. For all other vehicles, the ground is G201. Any open path in the ground path inhibits the alarm.

The lamps-on warning alarm is present when the headlights or the park lights remain on when the ignition switch is in the OFF position. The alarm remains present until the lights are turned off or until the ignition switch moves to the RUN position or to the START position.

With the headlamps or the parking lamps lighted, the multi-function alarm module senses voltage from the PARK LPS fuse 9 through the following path:

When the IP dimmer switch adjustment is for very dim illumination, the voltage sensed at the multi-function alarm module is sometimes too small for setting the logic and enabling the alarm. Verify the alarm function with an adjustment for the maximum illumination at the IP dimmer switch.

When the ignition switch is in the RUN position or in the START position, the multi-function alarm module senses voltage from GAUGES fuse 4 through CKT 39 (PNK). Voltage is present from the IP dimmer switch but not from GAUGES fuse 4 meets the alarm conditions.

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.
