Heated Seats
The controls for the heated seats are located on the side of each seat. The system offers two seat temperature settings of approximately 98.6 F (LO) and
approximately 107.6 F (HI).
As the temperature in the seat rises, the Negative Temperature Coefficient (NTC) resistance decreases and the voltage reading detected by the memory
heated seat/mirror module (MHSMM) increases. The seat heater output is deactivated once the voltage reading reaches it's upper threshold for either
setting, high or low.
As the temperature decreases, the voltage reading decreases until the lower threshold is reached for either setting high or low. At this point the seat heat
output is activated once again and this cycle repeats itself as long as the seat heat request is on. The thresholds for low and high settings are
pre-programmed into the MHSMM memory.
The heated seat switch contain resistors pulled up to ignition which are processed by the MHSMM as voltage readings indicating desired heat setting
high or low.

Mechanical Instrument Cluster (MIC)
The instrument cluster displays four gauges, a vacuum fluorescent (VF) odometer, a VF PRNDL and up to (18) indicators. One reset button is used to
switch the display from trip to total. Holding the button when the display is in the trip mode will reset the trip mileage. The cluster also supplies the
power for the panel illumination. Most of the information that is displayed is received over the PC bus from several modules.
With ignition in "lock", the cluster will wake up and display the door ajar and odometer display when a door is opened. The cluster will also wake up to
control the panel illumination. In "off" (unlock) the PRNDL and several indicators will be functional but all gauges will not function. On transition from
