Principles of Operation
The steering wheel rotational movement is
transferred to the steering gear through the steering
column shaft. The steering gear converts this
rotational movement, through the action of the rack
and pinion gear into lateral movement. This
movement in turn is transferred to the wheel
knuckles through the tie-rods and tie-rod ends.
Hydraulic fluid under pressure is supplied to the
steering gear by the power steering pump. As the
steering wheel is rotated, the hydraulic fluid is
allowed to pass through the steering gear valve to
one side of a double acting piston, dependent on
which direction the steering wheel is rotated. The
fluid moves the piston, which forms part of the
steering gear, giving power assistance to the effort
required to rotate the steering wheel.
Vehicles with petrol engines, due to the extra load
on the engine imposed by the power steering
pump, have a power steering pressure (PSP)
switch. The switch, which is normally closed, sends a signal
to the powertrain control module (PCM)
during low speed parking manoeuvres. The PCM
responds by maintaining the engine idle speed.

The fuel supply for all petrol fueled variants is
equipped with a return-less fuel system. This
means that the fuel delivery pressure at the fuel
injectors, is monitored and controlled by the fuel
tank module. This control is achived by switching
the fuel pump on and off.

Fuel composition monitoring fuel level sensor resistor card values.
The quantity of Ethanol E85 in relation to the
quantity of unleaded fuel contained in the fuel tank
at any one time is not monitored at the fuel tank.
The Ethanol percentage volume can only decrease
from its maximum 85% (pure Ethanol
E85), to zero
(1 00% unleaded fuel).
The fuel charging system compensates for the
changes in fuel composition using the signal
received by the power train control module (PCM)
from the
H02s. The PCM adapts the fueling and
ignition calibrations to suit the current fuel tank
content composition.
Cold start
To overcome the problems relating to cold start
inherent with Ethanol E85 vehicles (temperatures
down to -29 degrees centigrade), a block heater
has been installed into the engine coolant system.
The block heater is located to the rear of the engine
under the exhaust manifold. The block heater is
fitted with a dedicated harness which terminates at an external plug connector fitted into the radiator
grill.

The purpose of the starting system is to turn the
engine crankshaft at a speed which enables the
engine to start.
The engine is started as follows:

Ill.
The starter relay is activated by the PCM .
The solenoid is supplied with voltage.
The solenoid engages the starter motor pinion
with the flywheel ring gear.
The solenoid applies battery current to the
starter.
The starter turns the crankshaft until the engine
starts. The key can then be released and it
automatically returns to position
I I.
The system incorporates the "Smart
StartingWstrategy. This makes starting faster and
protects the starter.
If the driver fails to release the key immediately
after the engine starts, the PCM interrupts
activation of the starter relay and thus switches off
the electric starter motor.
The speed signal provided by the CKP sensor is
used for monitoring the starting procedure.

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).

operating mode.
Accelerator pedal position (APP) sensor
The PCM requires the pedal position from the APP
sensor in order to regulate the power output of the
engine according to the driver request for power.
The APP sensor is a double contact-less inductive
sensor.
If a concern occurs with the APP sensor while
driving, a diagnostic trouble code
(DTC) is stored
in the PCM.
If both sensors of the APP sensor fail, the engine
is regulated to a maximum engine speed of up to
4000 revlmin after a single operation of the BPP
switch and the stop lamp switch and a subsequent
comparative plausibility test. The vehicle can only
be accelerated to a maximum speed of
56 kmlh.

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

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

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.
