DESCRIPTION AND
OPEMION
Driver's side door ajar switch
The door ajar switch is located in the door lock on
the driver's side.
When the door is closed a ground connection is
signalled to the transmission control unit.
When the door is opened this ground connection
is interrupted.
The transmission control unit uses the signal from
the driver's side door ajar switch to warn the driver
if the selector lever is not in position
"P" and the
driver's door is open.
In this case the transmission control unit transmits
the warning tone request via the CAN
databus to
the instrument cluster.
The instrument cluster passes this request on to
the GEM, which then generates a warning tone.
Consequences of signal failure:
no warning tone request.
Actuators
Main regulating valve
Item Description
I 1 I Main regulating valve I
The main regulating valve is a proportional valve
which converts the applied electric current into a
proportional hydraulic pressure.
The currentless state corresponds to maximum
pressure.
/
The main regulating valve is used to determine the
main line pressure and therefore the actuating
pressure for the clutches and brakes.
Consequences of signal failure:
hydraulic emergency running mode.

DESCRIPTION AND OPERATION
Solenoid for the ignition key removal
inhibitor
Solenoid for the ignition key removal
inhibitor
The solenoid for the ignition key removal inhibitor
is integrated in the ignition lock.
With the selector lever in position
"P", the ground
connection via the selector lever lock solenoid is
interrupted.
The ignition key can be turned to
"0" and removed
from the ignition lock.
In all other selector lever positions the ground
connection is made via the selector lever lock
solenoid.
The locking pin of the solenoid for the ignition key
removal inhibitor engages in the ignition lock.
The ignition key cannot be turned to
"0" and
removed from the ignition lock.
Consequences of signal failure:
A short to ground will make it impossible to
remove the ignition key from the ignition lock.
A break in the electrical circuit will make it
possible to remove the ignition key from the
ignition lock in all selector lever positions.
