Sensor Value Check
WARNING: This page is about a different car, the 1999 Mercedes-Benz C230. However, it is still accessible from the selected car via links, so may be relevant.
Hand-Held Tester will display (in sequence) temperature sensor readings, refrigerant pressure, fan control voltage, software and control module version. This is useful in checking the tolerance range of temperature sensors and refrigerant pressure. Temperature control is maintained during test. To view these readings connect HHT and follow displayed procedures. See SENSOR VALUES table for description of readings.
