GENERAL DESCRIPTION
The car stop lights are operated each time the brake pedal is pressed; they are located at the rear in the side lights. The lights are turned on automatically through the switch on the brake pedal.
The circuit is protected by a special fuse.
The braking signal from the switch is also sent to the ABS system control unit which "recognizes" the situation and controls braking accordingly (see "ABS").
N.B.: In the versions on which a radio is installed, an anti-disturbance condenser is fitted on the switch to prevent interference in the area of the actual switch.
FUNCTIONAL DESCRIPTION
The stop lights circuit is supplied directly by battery voltage via fuse F2 of fusebox G1 (box "A" and "B"). For box "C" it receives the "key-operated" supply via fuse F15 of box G1.
The stop lights switch H3 comprises a contact which closes when the brake pedal is pressed, through which the stop lights are supplied in the rear side lights E19 (right), E20 (left).
For certain Versions/Markets the third central stop light E28 is foreseen
