NOTESPriorities when dealing with a number of faults:
–DF057 Water in diesel fuel detector circuit,
Special notes:
If water is detected downstream of the diesel filter, the high pressure pump and
the injectors may be damaged.
The level 1 warning light is illuminated.
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
See the Technical Note Wiring Diagrams for the vehicle.
If there is water present, bleed the diesel filter.
If there is a great amount of water, run the first part of Test 13: Diesel fuel conformity check (Is the fuel cloudy
or does it separate into 2 parts?)
Check the connections of the water in diesel fuel sensor, component code 414.
Check the connections of the engine management computer grey connector, component code 120.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
With the ignition on, check for +12 V on connections 3FB1 or 3FB2 (for New Twingo) or AP15 (for Kangoo 2) of
component 414.
Check for earth on connections M or 3WU (only for New Twingo) of component 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.

ET042CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITIONNOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off switch
is in the rest (or neutral) position.
LIMITER: This status indicates that the driver has used the main switch to select the
speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system programming
functions.
Conformity check: Engine stopped, ignition on or engine running.
NOT DETECTED If 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, the main switch
is in rest (or neutral) position and the injection computer has just 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 multiplex network test page on the Clip application. Repeat the
multiplex network test. Re-establish dialogue with the injection computer. Check
status 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 status ET042 is still NOT DETECTED, check that the vehicle's owner has not had
the cruise control/speed limiter function disabled in the past. Contact the Techline.

INACTIVE When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main switch being in the
rest (or neutral) position, carry out the following operations:
For Mégane II and Scénic II:
Check the connections of the cruise control/speed limiter main switch, component code
1081 (Mégane II) or 1546 (Scénic II).
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.
Check for + 12 V after ignition on the main switch connector.
●Connection code AP43, component 1081 (Mégane II) or 1546 (Scénic II).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
Disconnect the main switch and with it in the rest position, check the insulation between:
●Connection codes AP43 and 3FX, component 1081 (Mégane II) or 1546
(Scénic II).
●Connection codes AP43 and 3PD, component 1081 (Mégane II) or 1546
(Scénic II).
Check the continuity between connections AP43 and 3PD of component 1081
(Mégane II) or 1546 (Scénic II) at speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) or 1546 (Scénic II) at cruise control position.
If the checks are incorrect, replace the switch, component code 1081 (Mégane II) or
1546 (Scénic II).
Check the insulation, continuity and the absence of interference resistance on the
following connections:
●3FX between components 120 and 1081 (Mégane II) or 1546 (Scénic II),
●3PD between components 120 and 1081 (Mégane II) or 1546 (Scénic II),
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace the wiring.
Check the connections of the engine management computer, component code 120.
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.

STATUS DEFINITIONThis status indicates that the injection computer is blocking any change to the number
of passenger compartment air heating resistors active (active ones are not cut off, but
no more can be added). This freeze in the number of heating resistors is in response to
vehicle needs (availability of power, need for torque etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant temperature
> 80
°C
YESDepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required). Status ET111
becomes NO if the number of passenger compartment heating resistors engaged can
be freely controlled by the UCH.

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

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.

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.

If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405 Clutch pedal.

PR873OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle distance in km when the warning requesting the
oil change was displayed on the instrument panel.
NOTESThis parameter is not to be interpreted:
–on the K9K812 engine,
–if PR873 = 0 (Vdiag 58 only).
Conformity check: Engine stopped, ignition on or engine running.
The oil status is calculated by the oxidation program in the injection computer, depending on the engine revs.
When this count reaches a certain threshold before the end of the oil change period, the injection computer sends
a signal to the instrument panel, which will display "service required soon". PR873 corresponds to the vehicle
distance at the time this signal is sent.
The instrument panel computer will then count 900 miles (1500 km) before displaying the message "service
required".
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an oil change
within the remaining 900 miles (1500 km).
