Lower control panel control module, design - GF54.21-P-4116-02PP
The controls actually installed depend on the equipment level of the vehicle.
The Lower control panel control module (N72) consists of two blocks.
The left-hand block contains the actual control module with its link to the interior CAN.
The right-hand block merely contains switches and light-emitting diodes for the button illumination. This illumination is supplied with voltage from the upper control panel (N72/1) via a cable.
The two blocks are joined by a multi-pole cable.
