36 AUTOMATIC WINDOWS / ROOF HATCH / CENTRAL DOOR LOCKING
AUTOMATIC WINDOWS, DRIVER’S SIDE (OPENING)
(Switch in door panel, driver’s side)
If the automatic window switch (C745) is
activated and a connection is made (contacts 2
and 4), relay G030 will be activated through fuse
E044 and switch C745 (wire 4526). As a result,
a supply voltage is applied through fuse E034 to
connection point 2 of the motor (B003). The
other connection point (1) is connected to earth
through relay G031. The motor will start
operating counter-clockwise and the automatic
window on driver’s side will open.
AUTOMATIC WINDOWS, DRIVER’S SIDE (CLOSING)
(Switch in door panel, driver’s side)
If the automatic window switch (C745) is
activated and a connection is made (contacts 4
and 1), relay G031 will be activated through fuse
E044 and switch C745 (wire 4527). As a result,
a supply voltage is applied through fuse E034 to
connection point 1 of the motor (B003). The
other connection point (2) is connected to earth
through relay G030. The motor will start
operating clockwise and the automatic window
on driver’s side will close.
AUTOMATIC WINDOWS, CO-DRIVER’S SIDE (OPENING)
(Switch in door panel, driver’s side)
If the automatic window switch (C743) is
activated and a connection is made (contacts 2
and 4), relay G028 will be activated through fuse
E044 and switch C743 (wire 4522). As a result,
a supply voltage is applied through fuse E033 to
connection point 2 of the motor (B004). The
other connection point (1) is connected to earth
through relay G029. The motor will start
operating counter-clockwise and the automatic
window on co-driver’s side will open.
AUTOMATIC WINDOWS, CO-DRIVER’S SIDE (CLOSING)
(Switch in door panel, driver’s side)
If the automatic window switch (C743) is
activated and a connection is made (contacts 4
and 1), relay G029 will be activated through fuse
E044 and switch C743 (wire 4523). As a result,
a supply voltage is applied through fuse E033 to
connection point 1 of the motor (B004). The
other connection point (2) is connected to earth
through relay G028. The motor will start
operating clockwise and the automatic window
on co-driver’s side will close.
AUTOMATIC WINDOWS, CO-DRIVER’S SIDE
(Switch in door panel, driver’s side)
The automatic window control using C744 on
the co-driver’s side is similar to the automatic
window control on the driver’s side. When
switch C744 (connection between contacts 4
and 2) is engaged, relay G028 is activated
through switch C743 (contacts 5 and 2) and the
motor (B004) will open the automatic window.
When switch C744 (connection between
contacts 4 and 1) is engaged, relay G029 is
activated through switch C743 (contacts 3 and
1) and the motor will operate clockwise and
close the automatic window.
The automatic windows will only function if the
contact is switched on.
AUTOMATIC WINDOWS, CO-DRIVER’S SIDE
(Switch in door panel, driver’s side)
The automatic window control using C744 on
the co-driver’s side is similar to the automatic
window control on the driver’s side. When
switch C744 (connection between contacts 4
and 2) is engaged, relay G028 is activated
through switch C743 (contacts 5 and 2) and the
motor (B004) will open the automatic window.
When switch C744 (connection between
contacts 4 and 1) is engaged, relay G029 is
activated through switch C743 (contacts 3 and
1) and the motor will operate clockwise and
close the automatic window.
The automatic windows will only function if the
contact is switched on.
ROOF HATCH, OPENING
If the roof-hatch switch (C736) is used to make
a connection between contacts 2 and 6, and
therefore between contacts 1 and 3, a voltage is
applied to pin 1 of the roof-hatch motor (B175)
through fuse E030, switch C736 and wire 4761.
The roof hatch will open.
ROOF HATCH, CLOSING
If the roof-hatch switch (C736) us used to make
a connection between contacts 8 and 6, and
therefore between contacts 7 and 3, a voltage is
applied to pin 2 of the roof-hatch motor (B175)
through fuse E030, switch C736 and wire 4760.
The roof hatch will close.
CENTRAL DOOR LOCKING, CO-DRIVER’S
SIDE (STANDARD)
Purpose:
To lock the co-driver’s side door using
button/key or switch (C744). The driver can
lock/unlock the co-driver’s side door from behind
the steering wheel.
Central door locking motor, co-driver’s side
(B200):
The motor has two (internal) switches, i.e.:
- a “stroke-end” switch (always reverses at
end of stroke) (lower drawing);
- a switch which is mechanically connected to
the locking button (always reverses at the
beginning of the upward or downward
movement of the locking button) (upper
drawing).
Note:
A mechanical connection consisting of a linkage
mechanism between the cylinder lock and the
locking button will remain.
Starting position: door unlocked (see
drawing).
- The door is locked using the button/key.
The mechanical linkage reverses the upper
switch directly. As a result, a current will
flow through the fuse (E162), the
connection (30b), the motor, the lower
switch and the upper switch through
connection 31 to earth. The mechanical
linkage between the motor and unlock
button will move the button down.
Having reached the lower position, the
“stroke end” switch reverses.
The same occurs during unlocking. The
direction of rotation of the motor is the
same. The position of the switches is
different, however. The power between
motor/lock button is transmitted through a
lever/connecting rod mechanism.
- The door is locked using the switch (C774).
If the spring-loaded switch (C774) makes a
connection between connections 5/3 and 7,
point DL of (B200) is connected to earth.
One brief moment is sufficient to start the
motor moving. Because there is a
mechanical linkage between the motor and
the lock button, the upper switch will
reverse immediately afterwards. A current
will flow until the “stroke-end” switch breaks
the circuit.
- The door is unlocked using the switch
(C774). To this end, connection DO is
briefly connected to earth. The action is the
same, except that the switches resume
their other position once the locking button
has moved upwards.
Variants:
36 If the standard version is installed, the
driver’s side central door locking (B199) and
the central door locking electronic unit
(D862) will also not be installed. In that
case cascade G723 is placed on connector
394, and switch C744 replaces switch
C803.
CENTRAL DOOR LOCKING (OPTION)
Purpose:
- To automatically lock both doors if one of
the doors is locked using the key/button.
- To automatically lock both doors using the
alarm-system remote control (if available).
- If one of the two doors is unlocked, only this
door will open while other door remains
locked.
Description of central door locking, driver’s
side (B199) and central door locking motor,
co-driver’s side (B200).
The description of both components is similar to
description B200 as above.
Starting position: both doors locked.
Unlock the co-driver’s side door using the key.
This is the same as the standard version. The
other door remains locked.
Unlock the co-driver’s side door using switch
C803.
If switch C803 is engaged (connection between
pin 1 and 3/5), connection CO of component
B200 is connected to earth. B200 is activated in
the same way as in the standard version.
Starting position: both doors unlocked.
Driver’s side door locked using key/button.
The action is similar to that in the standard
version; in this case, however, unit D862 will
measure an earth signal through connection DL
(wire 4538) to pin 1. D862 now connects pin 2 to
earth, also activating B200. The co-driver’s side
door is now also locked.
Locking co-driver’s side door using key/button.
The operation is the same as the operation
described above. However, unit D862 now
measures an earth signal at pin 2 and will,
therefore, connect pin 1 of component B199 to
earth. The driver’s side door is now also locked.
Note:
If one or both door switches sends a positive
signal to pin 3 or 4 of unit D862, the
accompanying components B199 and/or B200
will not be activated.
