33 HEADLIGHT-HEIGHT ADJUSTMENT
OperationSee also the detailed drawing.
Rear/side marker and parking lights position
A voltage is applied to connection point 2 of the
lighting switch (C622) through fuse E084 and
wire 1101. If a connection is made (contacts 2
and 1) with switch C622, a voltage is applied
through wire 2100 to contact 85 of relay G000
(rear light/ side-light). Once the relay is
activated, a connection is made between points
30 and 87. As a result, a voltage is applied
through relay G000, wire 2101, fuse E117 and
wire 2630 to connection point A of switch C764
(potentiometer for headlight-height adjustment).
Only the LED in the switch will now light up.
Dipped beam position
If a connection is made between contacts 2 and
4 with switch C622, a voltage is applied through
fuse E084, wire 1101, switch C622, wire 2110 to
B129 (left-hand side headlight-height adjustment
motor), connection point 3, B130 (right-hand
side headlight-height adjustment motor) and
C764 (headlight-height adjustment
potentiometer). Depending on the position of
C764 (headlight-height adjustment
potentiometer), the motor in the headlight is
activated. The motor will remain active until an
electric state of balance is achieved. This state
of balance is the actual difference of voltage
between wires 2110 and 4953 of C764, B129
and B130. This difference of voltage should be
equal for all three components.
