CIRCUIT OPERATION1
CIRCUIT OPERATION
Sensors
Engine Speed Sensor (X255)
The engine speed signal is crucial to the system, as
the information from the sensor is used in virtually all
of the strategies within the `DDE (Digital Diesel
Electronics) and its Engine Control Module (ECM)
(Z132). Through this sensor, the ECM (Z132) knows
if the engine is turning, how fast it is turning and
approximately where the engine is in its cycle. The
sensor is of the `Hall effect type, which sends out a
pulse to...

DIESELA6
CIRCUIT OPERATION2
Boost Pressure Sensor
The boost pressure sensor signal is used in
conjunction with the air temperature signal to
calculate volume air flow into the engine. The sensor
is located on the rear bulkhead, with the pressure
tap just after the charge air cooler. If the sensor fails,
a substitute value of 490 hPa is used by the ECM
(Z132), producing a reduction in power due to a fuel
quantity limiting to 21mg/stroke.
Throttle Position Sensor (X171)
The DDE system is a `Drive by Wire...

DIESELA6
CIRCUIT OPERATION3
Fuel Quantity Actuator
Once again located within the injection pump, this is
a moving magnet actuator, failure of which will cause
the engine to stall or not start as the ECM (Z132) will
activate the Fuel Shut±Off Solenoid (K111).
Injection Timing (Solenoid Valve Injection Timing
Device (K229))
This is another actuator within the injection pump.
The ECM (Z132) receives a signal from the needle
lift sensor and attempts to correct the injection timing
accordingly. If a change...

DIESELA6
CIRCUIT OPERATION4
Main Relay
Located in the ECM (Z132) box, this relay supplies
the power feed to the ECM (Z132). It is controlled via
the Ignition Switch (X274) in position II.
Glow Plug Relay (Z135)
The Glow Plug Relay (Z135) takes a feed directly
from the battery and, on initialisation via the ECM
(Z132), supplies current to each of the six glow plugs
(one per cylinder) to aid cold starting. The glow time
is controlled via the ECM (Z132) which also monitors
the relay and illuminates the glow...
