3. Conditions for deleting an OBD fault
An OBD fault is deleted in several phases.
The fault present on the diagnostic tool will only become stored (after a repair operation) after the vehicle has
been driven 3 times.
The OBD warning light will only go out after these 3 trips.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the OBD fault and display parameters to be cleared from the computer, the system requires
40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
– the engine coolant temperature reaches at least 71.1°C,
– the engine coolant temperature varies by 22.2°C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored on the injection
computer.

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 declared present, consult the interpretation of status ET415 Cruise control/speed limiter
deactivation.
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values are
correct.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition has been switched on
Special notes:
The level 1 and European On Board Diagnostic warning lights are lit.
Use bornier Elé.1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
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.
