NTC resistor characteristics allow the resistance to decrease as the temperature rises. This means that the voltage fed over the resistor also decreases as
the temperature rises.
The voltage level from the A/D sensor is converted and is then available in digital form. The digital voltage level is then converted to a temperature
value which is stored in the ACC unit operating memory. Voltage levels near 0 V or 5 V are determined as circuit faults.
