Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The heated seat module is powered by battery and switched ignition voltage circuits 1048 (LB/WH) and 1040 (RD/BK). The heated seat is activated when the heated seat switch sends a ground signal to one of 2 input circuits into the heated seat module. Input circuit 1020 (DG/VT) activates HI or OFF. Input circuit 1255 (WH/RD) activates LOW or OFF. Once activated, the heated seat module supplies power and ground to the heater mat circuits 1064 (YE/LB) and 1065 (WH/LB) to heat the seat cushion and backrest. The heated seat module monitors circuits 1060 (BK/LB) and 1061 (BN/LB) from the temperature sensor in the cushion heater mat to maintain the seat temperature. The system will remain ON until the module times-out or is switched OFF.
