Heated Seats

When LO is pressed on the Heated Seat Switch and ignition Switch is in RUN, the Heated Seat Control Module LO input terminal is momentarily grounded. This causes the Seat Control Module to turn on the Heater in the seat. The Heated Seat Control Module monitors the seat surface temperature through a thermistor located in the center seat bottom. The Heated Seat Control Module will maintain the seat surface temperature at approximately 37.5° C (98.5°F) when LO has been selected. The Hi mode is similar to LO operation except the temperature increases approximately 5 degrees. When the OFF Switch is pressed, the Heated Control Module's OFF input is grounded momentarily. The module will react by turning off the voltage applied to the seat heaters The module will also turn off the Heated Seats whenever the Ignition Switch has been turned OFF. The passenger Heated Switch will not operate unless the Seat Belt is connected. This is a safety mechanism that insure that the seat will never be left on.
