303-1 4-9 Electronic Engine Controls 303-1 4-9
DESCRIPTION AND OPERATION
If one potentiometer fails, the engine will run with
reduced power (maximum torque
80 Nm), if both
potentiometers fail, the engine will run with reduced
power (maximum torque
55 Nm).
This warning may also be indicated if the engine
does not start. The cause may be a poor state of
charge of the battery.
The warning indication normally disappears once
the battery is re-charged.

303-1 4-1 2 Electronic Engine Controls 303-1 4-1 2
DESCRIPTION AND OPERATION
Powertrain control module (PCM) The KS detects engine vibrations caused by knock
and produces an output voltage signal in proportion
, to the knock. The PCM uses the voltage signal to(
control knock by retarding the ignition timing.
The powertrain control module is located within the
engine compartment below the battery and is
secured to the left-hand chassis rail by means of
a mounting bracket. On right-hand drive vehicles
the PCM is protected by a security shield which is
secured to the retaining bracket by a shear-head
bolt. In order to disconnect the PCM electrical
connectors it is necessary to remove the security
shield.
The PCM monitors and processes the signals from
the sensors and compares these with stored
parameters. The PCM uses this information to
calculate the output signals to the actuators.
Communications between the PCM and other
control units (for example, the stability assist and
the instrument cluster) including the DLC for
diagnosis of the system, take place on the
controller area network (CAN).
Intake manifold tuning valve solenoid
The solenoid for the intake manifold tuning system
is located on the transmission side of the cylinder
head.
Vacuum is supplied by a central vacuum
connection from the intake manifold.
The solenoid for the intake manifold tuning system
is supplied with either the maximum voltage or zero
voltage,
i.e. the valves are either fully open or fully
closed.
Actuation depends on the engine speed and the
engine load.
Diagnosis can be carried out through the DLC
using the Worldwide Diagnostic System (WDS)
BPP switch
diagnostic equipment.
Knock sensor (KS)
The BPP switch and the stoplamp switch are tt(r located on the pedal box and provide the PCM with
the information that the brake pedal has been
pressed and that the vehicle is therefore being
The knock sensor is located on the cylinder block decelerated.
