To diagnose the B3670 code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
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).
