Blinking

Power stage to supply the

6.1

Blinking

Crankshaft sensor: no signal
or implausible signal.

The engine will not start cold,
it could start warm with
difficulty.

With the engine running,
power

reduction

and

increased noise.

Check the integrity of the sensor (R =
approx. 850 Ohm).

If the sensor is sound, check the wiring
between

the

sensor

and

EDC

connector pin A29 — A37.

Check the sensor is fastened properly.

If there is no crankshaft signal, the camshaft sensor
speed signal is used instead.

Power reduction (and noise reduction because
the control unit cannot manage advance and
duration of injection and bases itself on a recovery
map. Pre-injection is not implemented).

6.2

Blinking

Camshaft sensor: no signal
or implausible signal.

The engine will not start cold,
it could start warm with
difficulty.

With the engine running,
power

reduction

and

increased noise.

False

injections

during

starting and smoke at the
exhaust.

Check the integrity of the sensor (R =
approx. 850 Ohm).

If the sensor is sound, check the wiring
between

the

sensor

and

EDC

connector pin A4 — A31.

Check the sensor is fastened properly.

If there is no camshaft signal, the flywheel sensor
timing signal is used instead.

6.4

Off

The

engine

has

over-revved (over 5500
rpm), probably driven,

or

crankshaft sensor signal not
plausible (in this case, error
6.1 signalled).

If the over-revving occurred
when driven, the driver can
detect no reaction (other
than

the

indicator

light

blinking).

Data saved to memory, check the
duration

and

frequency

of

the

over-revving.

Delete the fault memory.

Make the driver aware about using the vehicle
correctly.

8.1

Blinking

Pressure in rail too great.

The electric command fails
to reach the pressure
regulator.

The engine cuts out, loud
noise before cutting out.

Check that the connector on the
pressure regulator is connected.

If it is connected, check the wiring
between the regulator and the EDC
connector pin A9 — A20.

After a few times, the pressure relief valve might
remain open, in which case it has to be changed.

8.1

Blinking

Pressure in rail too great.

Pressure regulator
mechanically jammed
open.

The engine cuts out, loud
noise before cutting out.

Perform the high-pressure test with the
diagnosis instrument. If the outcome is
negative, replace the high-pressure
pump — regulator assembly.

After a few times, the pressure relief valve might
remain jammed open, in which case it has to be
changed.

8.1

Blinking

Pressure in rail too low.

Pressure regulator
mechanically jammed shut.

The engine cuts out or fails
to start.

Perform the high-pressure test with the
diagnosis instrument. If the outcome is
negative, replace the high-pressure
pump — regulator assembly.

8.1

Blinking

Pressure in rail too low.

Shorting to +Batt. on the
pressure regulator.

The engine cuts out or fails

Check

the

wiring

between

the

regulator and EDC connector pin A9 —
A20.

8.1

Blinking

Pressure in rail too low.

High-pressure pump
defective.

The engine cuts out or fails
to start.

Perform the high-pressure test with the
diagnosis instrument. If the outcome is
negative, replace the high-pressure
pump together with the regulator.

8.1

Blinking

Injector mechanically
jammed open.

The engine cuts out or fails
to start.

Perform the cylinder efficiency test
with the diagnosis instrument. If the
outcome is negative, replace the
defective injector.

8.1

Blinking

Pressure in rail too low.

Major fuel leak from the
high-pressure circuit.

The engine cuts out or fails
to start.

Check the high-pressure circuit and
eliminate the leak (beware, there could
be a leak inside the head between the
high-pressure union and the injector).
