IMMOBILISATION
The immobilisation control module receives information
from related systems on the vehicle and passes a coded
signal to the ECM to allow starting if all starting
parameters have been met. The information is decoded
by the ECM which will allow the engine to run if the
information is correct.
The information is on a rolling code system and both
the immobilisation control module and the ECM will
require synchronisation if either component is renewed.
The ECM also protects the starter motor...

CRANKSHAFT POSITION SENSOR
(CKP)
The CKP sensor is located at the rear of the engine block
on the left hand side. The sensor tip is aligned with a
magnetic trigger which is attached to the crankshaft.
The reluctor is a press fit on the end of the crankshaft.
The trigger wheel must be carefully aligned to the
crankshaft to ensure correct timing. The sensor produces
a square wave signal, the frequency of which is
proportional to engine speed.
The ECM monitors the CKP sensor signal and can detect
engine...

The MAF sensor output is a digital signal proportional
to the mass of the incoming air. The ECM uses this data,
in conjunction with signals from other sensors and
information from stored fuelling maps, to determine the
precise fuel quantity to be injected into the cylinders.
The signal is also used as a feedback signal for the EGR
system.
The IAT sensor incorporates a Negative Temperature
Coefficient (NTC) thermistor in a voltage divider circuit.
The NTC thermistor works on the principle of
decreasing...

•Limit engine operation if engine coolant temperature
becomes too high
•Cooling fan operation
•Glow plug activation time.
The instrument cluster uses the temperature information
for temperature gauge operation. The engine coolant
temperature signal is also transmitted on the CAN bus
by the instrument cluster for use by other systems.
The ECM ECT sensor circuit consists of an internal
voltage divider circuit which incorporates an NTC
thermistor. As the coolant temperature rises the
resistance through the...
