Control module PSM 5.3

The control module in the PSM 5.3 is installed at the front left of the luggage compartment. The installation position ensures that the control module plug can be pulled off only after the control module has been removed. The plug is designed so that the warning lights are activated if the connection is incorrect (short circuit bridge). The control module is located directly on the hydraulic unit.
