Chime System
Chime System
The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the
instrument cluster to request a chime from the CTM for gauge problems and tell-tale warnings. There are two chime rates, Low; 50 chimes per minute
for reminders and High; 180 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is
left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable
rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is
activated for six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated.
The chime will sound for the following conditions:
-
Ignition off, key in ignition, driver's door open
-
Ignition off, headlamps on, driver's door open
-
Seat belt warning
