Control module
The control module activates all the valves, the compressor and the LEDs. The control module is supplied by the vehicle electrical system (terminal 30) via an overload-protection relay with integrated reverse-connect protection. With voltage values below 9 Volts, the EDC-K system switches off. On the E65, the control module is located on the device holder behind the glove box. On the M3 E92, the control module is located in the device holder of the luggage compartment, rear right.
