Some vehicles have adopted a sensor for detecting water in the diesel fuel, located in the filter. If there is water in
the diesel fuel, the orange "Injection and pre-post heating" warning light will come on.
The system can inject diesel fuel into the engine at a pressure of up to 1600 bar. Before each operation, check that
the injector rail is depressurised and that the fuel temperature is not too high.
You must respect the cleanliness guidelines and safety advice specified in this document for any work on the high
pressure injection system.
Do not remove the internal parts of the pump and injectors. Only the flow actuator, the diesel temperature sensor
and the Venturi tube can be replaced.
For safety reasons, do not loosen high pressure pipe unions when the engine is running.
It is not possible to remove the pressure sensor from the fuel rail because this may cause circuit contamination
faults. If the pressure sensor fails, the pressure sensor, the rail and the five high pressure pipes must be replaced.
Do not remove an injection pump pulley marked with the number 070 575. If the pump needs to be replaced, replace
the pulley.
Supplying any system component directly with +12V is prohibited.
Ultrasonic decoking and cleaning are prohibited.
Never start the engine unless the battery is connected correctly.
Disconnect the injection computer when carrying out any welding work on the vehicle.
b)The connections between the vehicle's various computers are multiplexed.
The electronic system fitted in this vehicle is multiplexed. This system enables dialogue between the various vehicle
computers. As a result:
– the activation of the fault warning lights on the instrument panel is performed by the multiplex network, with the
vehicle speed sensor on the gearbox deactivated,
– vehicle faults are displayed by the multiplex network,
– the vehicle speed sensor on the gearbox is not needed.
The vehicle speed signal on the instrument panel is transmitted by the ABS computer via a wire connection, then
sent out on the multiplex network by the instrument panel. The vehicle speed signal is used mainly by the injection
computer and the airbag computer.WARNING
The engine must not operate with:
– Diesel fuel containing more than 10% diester.
– petrol, even in tiny quantities.

CLUTCH PEDAL SWITCH
STATUS DEFINITION"Inactive": this status indicates that the switch is released.
"Active": this status indicates that the switch is pressed.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
The clutch pedal is present depending on the gearbox type.
ACTIVE and clutch

Replace the switch if necessary.
Check the condition and fitting of the clutch pedal switch,
Check the continuity and the absence of interference resistance on connection 86D
between components 120 and 675.
If the connection or connections are defective and there is a repair method (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Check for an earth on connection MAM of the clutch switch.
Repair if necessary.
Remove the clutch pedal switch and check that it is functioning correctly.

Fault finding – Interpretation of statuses13B
ET415
CONTINUED 1
STATUS 3
Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405: "Clutch pedal".
If the vehicle is fitted with automatic transmission:
Carry out a multiplex network test, check the configuration of the multiplex network
according to the vehicle's technical definition and, in particular, the automatic gearbox
computer configuration (see 88B, Multiplex).
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either the cruise control is active, or
– the speed limiter is active
– and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 4 without pressing the 0 button, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the right-hand side of the steering wheel.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal indicating that the brake pedal switch has been
pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
– of status ET042 Cruise control/speed limiter,
– of status ET703 Cruise control/speed limiter buttons,
– of status ET704 Brake contact no. 1,
– and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 changes to "STATUS 5", deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6 when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) and:
– If the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is in neutral on an automatic gearbox.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into neutral on an automatic transmission, test
the ABS computer and check the configuration of the tyre size stored in the computer. If
the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ALP 10 Noise from the turbocharger
Apply Technical Note 5164A, Noise fault finding procedure.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
