OPERATION
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of each of the available audio systems.
CENTRAL TIMER MODULE
The high-line Central Timer Module (CTM) can
also control some features of the audio system when
the vehicle is equipped with the optional RAZ radio
receiver and remote radio switches. A high-line CTM
is used on high-line versions of this vehicle. The
CTM combines the functions of a chime/buzzer mod-
ule, an intermittent wipe module, an illuminated
entry module, a remote keyless entry module, and a
vehicle theft security system module in a single unit.
The high-line CTM also controls and integrates
many of the additional electronic functions and fea-
tures included on models with this option. The RAZ
radio receiver with a remote radio switch option is
one of the features that the CTM controls. The CTM
is programmed to send switch status messages over
the Chrysler Collision Detection (CCD) data bus to
control the volume, seek, and pre-set station advance
functions of the RAZ radio receiver. The CTM moni-
tors the status of the remote radio switches located
