INACTIVEWhen the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main button being in the
rest (or neutral) position, carry out the following operations:
Check the connections on the steering column top control module.
Check for +12 V APC on track 9 of the steering column top control module
connector.
Disconnect the top steering column control module connector and with the switch in
the rest position, check the insulation between tracks 9 and 6 and between tracks 9
and 12.
Check the continuity of the top steering column control module connector between
tracks 9 and 6, with the switch in the speed limiter position.
Check the continuity of the steering column top control module connector on
tracks 9 and 12, with the control in the cruise control position.
If the these checks do not produce the correct results, replace the steering column top
control module.
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.

ET415
1(CONTINUED)
STATUS 2Brake 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 RZ007
“Fault memory”.
If status ET415 becomes STATUS 2 without depressing the brake pedal, consult the
interpretation of statuses ET704 Brake switch no. 1 and ET705 Brake switch 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 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 an 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 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- 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, 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.
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

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
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 is pressed. These buttons are located on the steering wheel.
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.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364/370 Mechanical,
Electrical equipment 88C, Airbag and seat belt pretensioners, Driver's front
airbag, Removal - Refitting).
●Measure the resistance on the button between tracks P1 and P0 while pressing
the “+” button of component 331.
If the resistance is not approximately 300 , check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
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

RUN OBD TEST: O2 SENSOR
NOTESRepair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The aim of this command is to detect a fault causing the EOBD* threshold for pollutant emissions to be exceeded.
There are two kinds of oxygen sensor damage:
– mechanical damage to the component (breakage, cut in wire) which leads to an electrical fault,
– chemical or thermal damage to the component leading to a slower response time of the sensor and to the
increase in the average reaction time.
Procedure:
– Engine stopped.
– Run command SC007.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
Fault finding is entirely autonomous. When completed, the throttle control ceases and the engine returns to idling
speed regulation operation.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the sensor.
If the result is Status 3: the sensor is in good condition.
