1. DEF: Above maximum threshold
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started.
– a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited.
Use bornier Elé. 1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Note:
This fault is activated in case of considerable oil dilution due to a significant number of particle filter regenerations.
Carry out the following:
– An oil change (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 10A Engine and peripherals,
Engine oil: Draining – Filling),
– reset the oil wear meter,
– clear the faults.
Reset the oil wear meter after the oil change:
It will be necessary to reinitialise the display of the trip computer.
With the ignition on:
– hold down the TC* button for 5 s.
Re-initialisation has worked when the on-board computer no longer displays the key.
If this is not the case, restart the procedure.
Specific case:
If an oil change is performed before the oil service interval warning is exceeded, reinitialise the display.

ET143
CONTINUED
Sensor electrical conformity
ACTIVEWhen the coolant reaches 99°C, the injection computer commands the low-speed
relay of the fan assembly, and status ET143 becomes ACTIVE. The relay then
supplies the fan assembly and the cooling fan begins to turn.
If status ET143 is ACTIVE, but the cooling fan is not running, perform the following
operations:
– Check the condition of fuse FM15 (60 A) in the engine fuse and relay box.
Disconnect the low speed and high speed relays, check their operation and the status
of the connectors of the relay mounting (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Component code 597).
If the connector or connectors are faulty and if there is a repair procedure (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector. Otherwise replace the wiring.
Check for the supply of + 12 V after the relay to the low-speed relay of the fan
assembly:
– Connection 3FB of component 700.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49L between components 700 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 262 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 3JN between components 700 and 120.
Check that the earth is in order on the MAS connection of component 262.
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.
INACTIVEIf the engine temperature is lower than 99°C, the engine cooling fan cannot switch on
and the low speed fan relay of the cannot be run.
Status ET143 must therefore be INACTIVE when the control relay and the engine
cooling fan are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
