CHECK COOLING FAN 2
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOTE:
Status ET015 GMV 2 test and status ET021 High speed GMV request change their status at the same time.
RUNNING
The engine fan assembly can be supplied when:
–the engine coolant temperature is above 99 ˚C.
–the injection computer has system faults that could lead to the engine overheating.
When the high speed fan is supplied:
–status ET015 GMV 2 test becomes RUNNING and status ET021 High speed GMV
request becomes ACTIVE.
The high-speed engine fan assembly stops when:
–the engine coolant temperature is below 99 ˚C;
IMPORTANTWARNING
If the UPC does not detect the injection computer frames, the low speed engine
fan is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is faulty, the high-speed
engine fan assembly will then be activated.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

ELECTRIC COOLANT PUMP
NOTESThis command allows you to check the operation of the electric coolant pump.
Test the electric coolant pump relay (A 20A) and check it is operating correctly.
Check the injection computer connections.
Repair if necessary.
Check the continuity between the following connections: Tracks B1 and B5 of the coolant pump relay mounting.
If the checks yield the correct results, check the continuity and absence of interference resistance on the
following connections:
Injection computer brown 48-track connector B,
track H4Track B2 of the coolant pump relay mounting
Injection supply relay mounting, Track 5Track B1 of the coolant pump relay mounting
Injection supply relay mounting, Track 5Track B5 of the coolant pump relay mounting
Turbocharger bearing coolant pump connector,
Track 1Track B3 of the coolant pump relay mounting
Turbocharger bearing coolant pump connector,
Track 2Earth
Repair if necessary.
If the fault is still present, contact the Techline.

Check that the heater plugs are actuated using the AC001 Preheating unit command.
Check the sealing and condition of the inlet circuit: run test 3 Turbocharged air inlet circuit check and follow the
fault finding procedure.
Check that there are no foreign bodies on the flowmeter grille: run test 4 Air flowmeter and follow the fault finding
procedure.
Check that the exhaust is not blocked: run test 1 Exhaust pipe check and follow the related fault finding
procedure.
Check the consistency of the signal from the engine coolant temperature sensor.
Check the pressure regulator is working properly (see command AC011 Rail pressure regulator).
Check the operation of the injectors (excessive return leak, clogging, seizing): run test 8 Poor injector operation.
Check the engine timing (and the position of the high pressure pump sprocket).
Check the balance of the compressions, according to the power consumption during the starting phase
(Compression test menu on the CLIP Technic tool).
If you do not have the CLIP Technic or if there is an imbalance, use a compression gauge to get an accurate
measurement.
after the operation, clear the faults caused by disconnecting the regulator and the heater plugs.

Is the engine running on all cylinders?
NO
Check the operation of the injectors: apply test 8 Incorrect injector
operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve and the damper valve.
–Check the consistency of the signal: of the air flowmeter, of the engine coolant temperature sensor, of the fuel
temperature sensor and of the engine speed.
Check the connections, continuity and absence of interference resistance on the air flow sensor (apply DF056 Air
flow sensor circuit, 2.def), the engine coolant temperature sensor (apply DF001 Coolant circuit, 1.def), and the
engine speed (apply DF195 Camshaft sensor/engine speed consistency, 2.def).
Check: – That the diesel filter is not clogged (for the test, see DF053 Rail pressure regulation function
2.def).
–That there are no leaks on the high and low pressure diesel circuits: apply test 3 Turbocharged
air inlet circuit check.
–That the oil vapour rebreathing system is connected.
–The flow regulator (blocked/seized, apply the interpretation for command: AC011 Rail pressure
regulator).
–Check the timing setting (and the position of the high pressure pump sprocket) (see MR 364 (MEGANE II) or
370 (SCENIC II), Mechanical, 11A, Top and front of engine).
–Check the cylinder compressions (balance of the cylinder compressions with the Compression test function
on the CLIP Technic diagnostic tool).
–Measure the engine compressions using the special tool.
If the fault is still present, contact the Techline.YES
