Code B1925 Cadillac 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 Seat Heating Control Module supplies a 5 V reference voltage through the temperature sensor signal circuit and a ground through the low reference circuit to the sensor. The module monitors the voltage of the sensor signal circuit to determine the temperature of the seat. The temperature sensor varies in resistance based on the temperature of the heating element causing the signal voltage to change. Once the seat reaches the set temperature, the module will then cycle the control circuit of the heating elements ON and OFF in order to maintain the desired seat temperature based on the feedback voltage from the sensor.
