Control Assembly: Description and Operation
Control Module
Control Module
The control module is integrated in the MCC unit and is activated by +15 or by the parking heater input. If the control module is activated, the fan speed
can be regulated.
If the power supply falls below 9.5 V, all the stepping motors will cease to function until the voltage rises above 1O V.
Diagnostics
The control module is not connected to the bus and does not communicate with Tech 2. A stored diagnostic trouble code is flashed six times in
succession by the LED for the electrically heated rear window if the button is depressed while turning on the ignition, and for a further 2 seconds after
that.
Only one fault can be stored at any one time. Diagnostic trouble codes are deleted by calibration after rectifying the fault.
There is no diagnostic trouble code for internal faults in the control module.
