Incorrect fitment
Belt noise can be generated by the belt being
incorrectly fitted on the pulley as shown in the
following illustration. Make sure that all the V
grooves on the belt contact correctly with the
pulley.

303-1 4-7 Electronic Engine Controls 303-1 4-7
DESCRIPTION AND OPERATION
Function The throttle flap position is adjusted and monitored
in a closed control loop. The TP sensor provides
I A CAUTI0N:The throttle control unit (TCU)
the PCM with the information on the actual position
must not be dismantled. No adjustments
of the throttle flap.
or repairs can be made to the TCU.
Item Description
I I I stop screw I
1 2 IToothed segment I
1 3 1 Throttle flap spindle I
1 4 1 Throttle flap return spring I
1 5 1 Intermediate shaft with gear I
1 6 1 Electric motor with pinion I
The APP sensor sends the data containing the
driver's acceleration requirement to the PCM. This
information depends directly on the movement of
the accelerator pedal.
The PCM processes this information and converts
it into an output signal for the throttle control unit
(TCU). This output signal is the control for the
electric motor.
The electric motor moves the throttle flap spindle
by means of the gear set.
Standby function
If a fault develops in the throttle control unit (TCU),
a standby function is carried out. This standby
function allows a slight opening of the throttle flap, so that enough air passes through to allow limited
engine operation.
For this purpose, there is an throttle flap adjustment
screw on the throttle housing. The return spring
closes the throttle flap until the stop of the toothed
segment touches the stop screw. In this way a
defined throttle flap gap is formed for limp home
mode.
The stop screw has a spring loaded pin, which
holds the throttle flap open for limp home mode.
In normal operating mode, this spring loaded pin
is pushed in by the force of the electric motor when
the throttle flap must be closed past the limp home
position
(e.g. for idle speed control or overrun
shutoff).
CPP switch
The CPP switch is located directly on the pedal
box.
The engine management recognises gearshifts
through the CPP switch and thus improves engine
running characteristics.
The CPP switch passes a ground signal to the
PCM when the clutch pedal is depressed
(disengaged).

307-01 -30 Transmission (AW81-40) 307-01 -30
DESCRIPTION AND OPERATION
The transmission control unit can be diagnosed
with WDS via the DLC.
Gearshift strategies
Gearshift control
I A I Accelerator pedal position I
I B I vehicle speed 1
The current ratio is selected by the transmission
control unit either in accordance with the
requirements for low fuel consumption or in order
to meet the required driving performance.
The gearshift timing is selected in accordance with
a gearshift map which is programmed into the
control unit as a function of the accelerator pedal
position and the vehicle speed.
For kick-down (accelerator pedal pressed down at
least
95 %) the next lowest gear is selected, as
long as the engine speed allows it. All gearshift
timings are set by the transmission control unit to
the upper shift characteristic. The driver can feel the
kickdown point
in the
accelerator pedal as a slight increase in resistance
to the operation of the pedal.
This is influenced by the following variables:
accelerator pedal position and actuation,
vehicle speed,
brake pedal position,
selector lever position.
The following are actuated:
SSA shift solenoid valve,
SSB shift solenoid valve.
Hill climb mode
When the vehicle is in hill climb mode or towing a
trailer, the transmission control delays gearshifts
to prevent frequent shifting back and forth between
the gears.
