– Carry out an After-Sales regeneration.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
– At the end of After-Sales regeneration, if the CLIP diagnostic tool indicates that you must replace the particle
filter, perform a oil change and replace the oil filter.
Explain to the customer the procedure for regeneration when driving to limit future garage repairs: see PART D in

PART B
1. No particle filter regeneration.
2. Write on the repair order the parameter and status relating to the last failure:
Mileage of last DF312
Mileage of last failures
Engine statuses of last failures
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3. Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the Particle Filter message or warning light illuminated (appeared at the Mileage of the
last DF312), the customer had not adhered to the driving recommendations: the failure that occurred at the
Mileage of the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PA R T D.
PART C
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
Carry out an After-Sales regeneration with the consent of the Techline.
Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

PART D
Procedure to switch off the Particle filter message or warning light on the instrument panel
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. When the engine is warm, drive at a speed greater than 36 mph (60 km/h) for 1 minute to trigger the
regeneration procedure.
2. Keep driving at an average speed of 36 mph (60 Km/h), until the particle filter message or warning light on
the instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
the engine or leaving the engine running at idle speed for an extended period of time. The regeneration time
depends on the vehicle and driving conditions but should last for 20 minutes maximum.
3. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. Run command SC017 Particle filter
regeneration (see interpretation of commands).
Check that there are no leaks or blockages in the exhaust pipe.
Repair if necessary
If the fault is still present, contact the Techline.

NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present during an After-Sales regeneration carried out using the
diagnostic tool at a speed above zero.
Special notes:
If the fault is present:
– regeneration in progress is stopped.
IMPORTANT
The fault is present because the vehicle was driven while the After-Sales regeneration was in progress.
The vehicle must remain stationary throughout regeneration.
DO NOT DRIVE THE VEHICLE DURING AFTER-SALES REGENERATION.
CHECK THAT THE VEHICLE IS CORRECTLY IMMOBILISED.
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer supply.
– switch on the ignition,
– establish dialogue with the injection computer,
– clear the faults from the computer memory.
Check that there are no leaks or blockages in the exhaust pipe,
– Repair if necessary
– carry out another After-Sales regeneration,
– run command SC017 Particle filter regeneration and follow the procedure (see Interpretation of commands).
If the fault is still present, contact the Techline.

ABSENT
NOTESIgnition on
If the ignition is not switched on, the status ET001 must be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. The status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
Check the status of fuse FM3 (30A) in the engine fuse and relay box.
Check the continuity and absence of any interference resistance on the following connection:
– connection code 3AA between components 120 and 983.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, contact the Techline.

STATUS 1
Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active
(ET042 Cruise control/Speed limiter: CRUISE CONTROL) and traction control is
requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-
lock Braking System).
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 depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
Fault memory.
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult the
interpretation of statuses ET704 and ET705 Brake switch No. 1 and No. 2.
