Cruise control/speed limiter management:
When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the driving
conditions encountered. Using the control buttons, the driver can increase or decrease the vehicle speed.
The cruise control function can be deactivated either by using the control buttons or by switching off the cruise
control function selection switch, or when system events are detected such as depressing the brake or clutch
pedals, or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle
deceleration. The cruise control function can also be temporarily suspended when the driver wants to resume
control of the vehicle and exceed the selected cruising speed by depressing the accelerator pedal which then
exceeds the selected fuel flow. The cruising speed is resumed when the driver releases the accelerator pedal.
The cruise control function can be reactivated and the last cruising speed can be resumed after deactivating
the function for whatever reason until the vehicle ignition is switched off (i.e. for as long as computer supply not cut
off). The vehicle will then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When switched on (using the selection switch), the vehicle speed limiter function limits the vehicle speed to a preset
value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached.
If an attempt is made to exceed this speed, the system will ignore the pedal request and will control the vehicle
speed as the cruise control function would do, provided that the driver continues to press the accelerator pedal.
As with the cruise control function, the set speed can be altered by adjusting the control buttons, with single touches
or holding down.
For safety reasons, the cruising speed can be exceeded by depressing the accelerator pedal beyond the pedal
position limiting value. Vehicle speed is then controlled using the accelerator pedal until the vehicle speed is
decreased to below the cruising speed, when the limiter function is activated again.
The driver has the following controls for the cruise control/speed limiter function:
– accelerator pedal,
– brake pedal,
– clutch pedal,
– function selector switch, used to select cruise control or speed limiter operating mode.
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This concerns 5
functions: the MIL (Malfunction Indicator Lamp) of the EOBD (European On Board Diagnostic), pre-postheating,
the coolant temperature, and engine faults: Level 1 (non-critical fault) and Level 2 (emergency stop). These five
functions are represented by 3 warning lights or messages displayed by the on-board computer.
Pre-postheating warning light
This light is used both as an in-operation indicator light and as a system fault indicator:
– permanently lit during + after ignition feed: indicates preheating of the heater plugs.
After preheating and an automatic timed 3 second off period, the warning light will come on if a Level 1 fault occurs
(leading to reduced operation and reduced safety levels. The driver should have repairs carried out as soon as
possible.)

STATUS 2
Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with cruise control active
(ET042 Cruise control - speed limiter: CRUISE CONTROL) and the brake pedal is
depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult
the interpretation of statuses ET704 and ET705 Brake contact No. 1 and No. 2.
STATUS 3Clutch 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 the 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
RZ001 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:
Test the multiplex network: check the configuration of the multiplex network in relation
to the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, MULTIPLEXING).

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 that the brake pedal switch has been
pressed.
If status ET415 is STATUS 5, consult the interpretation:
– of status ET042 Cruise control/Speed limiter,
– of status ET703 Cruise control - speed limiter buttons,
– of status ET704 Brake switch no. 1,
– and status ET705 Brake switch no. 2,
to test the cruise control/speed limiter system components and locate the faulty
component.
Also, check the operation of the accelerator pedal, and use the diagnostic tool to
check the presence of a fault connected with this component. Deal with them if
necessary.
Reinitialise status ET415 on the injection computer by running command
RZ001 Fault memory.
If status ET415 becomes STATUS 5, deal with the present faults or those stored in
the injection computer.
If the fault is still present, contact the Techline.
