Circuit/System Description
The heated seat temperature sensor that set this diagnostic trouble code (DTC) is located in the seat cushion just under the seat cover with the seat
heating element. The temperature sensor is a 2 wire thermistor and resistance through the sensor varies with temperature. The signal circuit is
referenced from 5 V within the memory seat module (MSM) and the temperature of the seat surface determines the signal circuit voltage. Once the
seat reaches the set temperature, the MSM will then cycle the control circuits of the heating elements ON and OFF in order to maintain the desired
seat temperature based on the feedback voltage from the sensors.
Conditions for Running the DTC
The MSM must be powered.
Conditions for Setting the DTC
B1925 02 or B2170 02
The temperature sensor voltage drops below 0.80 V for more than 1 second.
