B3670 PONTIAC Description
The Folding Ttop Control (FTC) Module monitors the folding top pump motor temperature, checking the temperature once every 300 milliseconds. The FTC module supplies a 5-volt reference and monitors the sensor low reference voltage from the thermistor located in the folding top pump motor. As the pump motor warms up and the temperature increases, the thermistor resistance will increase. The FTC module monitors the voltage drop across the thermistor and uses it to calculate the temperature of the pump motor. When the FTC module detects that the temperature is above the maximum operating range, it will set this Diagnostic Trouble Code (DTC).
