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.)

ET042 CRUISE CONTROL/SPEED LIMITER
NOTESNone.
NOT DETECTEDIf the vehicle is not fitted with cruise control - speed limiter function buttons, status
ET042 is permanently NOT DETECTED. This confirms that the cruise control/speed
limiter function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons and the main
switch is in the rest (or neutral) position and after the injection computer has been
programmed or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in
the cruise control position and then in the speed limiter position.
Return to rest position
The tool displays status ET042: INACTIVE.
If not, several steps must be checked:
1. Return to the page on testing the multiplex network with the CLIP program.
Repeat the multiplex network test. Re-establish dialogue with the injection
computer. Check ET042. If ET042 is INACTIVE, the injection computer has
detected the various positions of the main switch. The cruise control/speed
limiter is active.
2. If ET042 is still NOT DETECTED, check that the owner of the vehicle has not
had the cruise control - speed limiter function deactivated in the past. Contact
Techline.

STATUS 4
Cancel 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
RZ001 Fault memory.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control - speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.

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.

Only perform these tests if the statuses do not correspond with the system programming
functions.
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control - speed limiter
buttons are pressed. These buttons are located on the steering wheel.
To remove the driver's airbag to perform the checks in complete safety.
(see 88C, Airbag and pretensioners)
If status ET703 does not display INACTIVE,
• check the condition of the cruise control/speed limiter +/- button and the condition
of its connector.
• check the condition of the cruise control/speed limiter R/0 button and the condition
of its connector.
Repair if necessary.
