NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
The cruise control/speed limiter function is inhibited.
Use bornier Elé. 1681 for all operations on the injection computer connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
If fault DF051 is present, refer to the Cruise control/Speed limiter section of the conformity check and refer to
interpretation of statuses ET042 Cruise control/Speed limiter, ET415 Cruise control/Speed limiter
deactivation and ET703 Cruise control/Speed limiter buttons.
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values
are correct.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various factors that cause deactivation of the cruise control/speed limiter function, due to a
driver request or the external environment (e.g. STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ001 Fault memory to reset this status to NONE.
WITHOUTThis status is present on the diagnostic tool when:
The computer has been reinitialised.
The computer has been reprogrammed.
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
“Fault memory”.
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
Braking System).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

STATUS 2Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2, when driving with the 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 with no application of 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 switch.
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 specifications and, in particular, the automatic
gearbox computer configuration (see 88B, multiplex).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
