Integration of the function into the vehicle

The "electrically adjustable rear spoiler" function is implemented in the convenience system central control 
unit J393. The control unit activates the adjustable rear spoiler motor V52 and reads in the two limit switches 
F135 and F136, which are used to identify both limit positions of the rear spoiler.

The convenience system control unit J393 also reads in the adjustable rear spoiler switch E127 and activates 
the adjustable rear spoiler warning lamp K242 in the button according to the current status.

Electrical system and convenience electronics

Design of the "electrically adjustable rear spoiler"

The "electrically adjustable rear spoiler" consists of two components which can be ordered separately:

●

the rear spoiler module

●

the spoiler wing

A DC motor mounted on the rear spoiler module transmits a rotary movement to the input shaft vi a gear and 
special joint (four-way joint). The shaft converts this movement to a lifting movement by means of left and 
right reversing mechanisms. The lifting movement moves the spoiler wing mounted on the rear spoiler 
module from the lower limit position to the upper limit position or vice versa, depending on momentary 
position of the rear spoiler.
Two limit switches for detecting the lower and upper limit positions are actuated by the four-way joint.
