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.

DESCRIPTION AND OPERATION
Item Description
I I 1 Cover I
1 2 I Adjusting ring (ramp ring) I
1 3 1 Spring I
1 4 1 Sensing Belleville washer I
r5 1 Main Belleville washer I
A conventional clutch responds to clutch wear with
an increase in the release force, which ultimately
has to be delivered by the driver to press down the
clutch pedal.
This increase in the release force after clutch wear
is used on the self-adjusting clutch as the key
indicator for adjusting the clutch. The main
distinction to a conventional clutch is that
the main Belleville washer is not riveted in a fixed
-
manner to the cover, but instead is supported by (
a so-called sensing Belleville washer. In addition
an adjusting ring (ramp ring) is used to compensate
the wear of the clutch lining.
The sensing Belleville washer is hooked into the
clutch cover at the outside and, with the inner
tongues, forms the bearing for the main Belleville
washer.
The sensing Belleville washer is designed to deliver
a slightly greater opposing force under normal
conditions than the maximum required release
force.
Item Description
If when the clutch is operated the release force is
less than the opposing force of the sensing
Belleville washer, then the pivot bearing point of
the main Belleville washer remains in the same
position.
If however the release force increases due to lining
wear, then the opposing force of the sensing
Belleville washer is exceeded. If the
opposing force of the sensing Belleville
washer is exceeded, the sensing Belleville washer
and therefore also the main Belleville washer are
displaced towards the flywheel.
This displacement towards the flywheel has the
effect that the release force is reduced again.
Once the release force has dropped to the level of
the opposing force of the sensing Belleville washer
again (equilibrium of forces), the displacement of
the components towards the flywheel stops.

DIAGNOSIS AND TESTING
PCM to the electronic throttle body including
the electrical connectors in area "B" (see
system overview).
- There is an obstruction inside the throttle
body bore. Remove the air cleaner outlet pipe
and check for obstructions.
- There is an obstruction inside the electronic
throttle body. Remove the air cleaner outlet
pipe and check that the plate moves freely
against the springs and returns to a slightly
open position. If it does not, install a new
electronic throttle body.
P2176 - Throttle plate adaptation error
- When the ignition is turned off, the throttle
body carries out an adaptation cycle and
spring check. This can be audible after a
short delay (up to 30 seconds) following the ignition key being turned to position
0 and
can be visually observed with the air cleaner
outlet pipe removed. The throttle plate is
moved through a series of positions to check
the TP sensor value and relearn the
electronic throttle body characteristics. If a
concern is detected during this test,
P2176
DTC will be set. If there are already any of
I the other DTCs, the adaptation test could
potentially fail. Therefore the other DTCs
should be resolved first
(e.g. low battery
voltage) and a retest can be carried out by
clearing the DTCs and keying on and off
again. Check the whole area "B" (see system
overview) for any concerns and if no concern
is found, install a new electronic throttle body.
P2100 - H bridge error
- A fault has been detected on the circuit
connecting the electronic throttle body motor
and the PCM. Check for any other
non-electronic accelerator control related
DTCs and rectify them first. Check area "B"
(see system overview) and if no failure is
found, install a new PCM.
PCM Related Codes
The PCM continuously monitors all the sensors. It
also checks that the monitor is functioning as
expected. If there is a fault with the monitor, the
following DTCs will be set.
P2107 - Processor monitoring on the main
controller fault.
P2108 -Analogue to digital converter
- Inferred intake mass air flow lower than
expected
- Engine speed monitor ratio error
- Pedal ratio monitor error
- TP sensor ratio monitor error
- Fault in torque generation
- Fault present in engine speed limitation
Multiple sensor faults can make the PCM assume
that there is a monitor fault. If other DTCs exist,
rectify these first. These DTCs indicate a failure in
area
"A or "B" and they are also related to the
manifold absolute pressure and temperature
(MAPT) sensor and the crankshaft position (CKP)
sensor. If no other failures are found, install a new
PCM.
Indirect Codes
There are two brake pedal switches located under
the brake pedal. Check that both of these are
connected and functioning correctly. A brake pedal
switch concern will only cause the "EAC FAIL"
message to be displayed, it will not lead to a limited
performance mode. Follow WDS instructions.
PO571 - Brake switch error
If the voltage to the accelerator pedal and the
electronic throttle body cannot be regulated
correctly, the components may not operate as
expected. Therefore it is important to detect if there
is a concern in the supply voltage
PO641 - Sensor voltage supply circuit I noisy
