Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

Each thermo-electric device (TED) contains an internal temperature sensor (thermistor) that is used by the climate controlled seat module (CCSM) to monitor the temperature of each (TED). Based on the temperature of a TED, the internal sensor resistance will vary the voltage on circuit 8-HC24 (WH/RD) (seat cushion TED) and circuit 8-HC19 (WH/BK) (backrest TED).
