STEPWELL LIGHTING, DRIVER’S SIDE
If the driver’s side door is opened, switch E514
will close and the driver’s side stepwell lamp
(C062) will light up. A voltage is also applied
through wire 2600 to pin 17 of the CTE-2 unit
(D550). A voltage will be also be applied
internally to connection point 27 of CTE-2 unit
(D550), causing a lamp on the driver’s side
interior lighting (C149) to light up.
If the driver’s side door is closed, a voltage will
be applied to connection point 27 of the CTE
unit for approx. 9 sec. This will result in a delay
in switching off the interior lighting. If a speed
signal is applied to pin 18, the delayed switch-off
will not function. The stepwell lighting is
independent of the contact switch position.
STEPWELL LIGHTING, CO-DRIVER’S SIDE
If the co-driver’s side door is opened, switch
E515 will close and the co-driver’s side stepwell
lamp (C063) will light up. A voltage is also
applied to C148 (interior lighting, co-driver’s
side) through wire 2609, diode D708 and wire
2633.
INTERIOR LIGHTING UNDERSIDE ROOF
CONSOLE
A voltage is applied to switch C151 (interior
lighting with middle switch) through fuse E030
and wire 1104. Depending on the switch
position, C151 (interior lighting underside roof
console) will light up.
