If the fault is stored, clear the fault from the computer memory.
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching
the ignition back on.
Start the engine and re-establish dialogue.
This fault may be linked to a write error following disconnection of the battery when the computer was in the
process of writing to the EEPROM phase (computer memory).
If this is the case, loading a new calibration will remove the fault.
If a more recent calibration is available, load this calibration on to the computer.
If the fault is still present:
– use the command RZ034 Computer memory,
– Switch off the ignition and wait for the computer dialogue lost message,
– switch on the ignition again,
– define the injector codes using the control SC002 Enter injector codes.
– Run the programming commands (See configuration and programming),
– switch off the ignition and wait for the message loss of communication with the computer.
Perform a road test to reinitialise the vehicle parameters.

Check the condition of the connectors on the differential pressure sensor and the injection computer.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Check the continuity, insulation and the absence of interference resistance on the following connections:
– Connection code3AAQ,

is not present on the vehicle.
INACTIVE: This status indicates that the main On/Off switch of the cruise control/speed
limiter 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.
Use the Mégane II ph2, Scénic II ph2 Technical Note wiring diagram.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
