ELECTRIC COOLANT PUMP
NOTESThere must be no present or stored faults.
Switch on the ignition and run command AC027 Motorised throttle.
If the coolant pump is not working.
Check the cleanliness, condition and fitting of the coolant pump.
Top up the coolant if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any harness damage, and check the condition and connection points of the injection computer and the
coolant pump connectors.
Repair if necessary.
If the fault is still present, check for +12V on track 2 of the coolant pump.
If +12V is not present on track 2 of the coolant pump, check the following connection for insulation, continuity
and the absence of interference resistance:
Coolant pump track 2 track 6, connector CN, of the Protection and
Switching Unit
Repair if necessary.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connection:
Computer, connectorB, track L4 track 1 of the coolant pump
Repair if necessary.
If the fault is still present, check that the resistance between tracks 1 and 2 of the coolant pump is neither zero
nor infinite.
Replace the coolant pump if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

TEST 2 Camshaft dephaser solenoid valve
Special NoteTo apply this method, it is necessary to use the special tool Elé. 1793, available in the
Parts Department catalogue.
Vdiag 4C only
– Disconnect the solenoid valve connector.
– Measure the electrical resistance between the
terminals of the solenoid valve at 20°C.
Is the electrical resistance of the solenoid valve
between 6.7Ω and 7.7Ω?
YES
Use the tool Elé. 1793 in accordance with the
method below:
– connect the tool to the solenoid valve and to
the vehicle battery,
– start the engine and maintain idle speed,
– actuate the solenoid valve with the tool
(by pressing on the button).
Does the engine stall and/or is the idle speed
very unstable?
NO
– Switch off the engine.
– Use the tool Elé. 1793 to operate the solenoid
valve. Press several times successively to hear
the solenoid valve.
NO– The solenoid valve is faulty.
– Replace the solenoid valve with a new one.
YES– The pulley-dephaser and the solenoid valve
operate.
– Check the injection computer, camshaft
sensor, TDC sensor and their wiring and
respective connections.

NO
– Remove the solenoid valve from the engine.
– Use the tool Elé. 1793 to operate the solenoid
valve. Press several times successively to see
the valve move.
Does the valve move?
NO
– The solenoid valve is faulty.
– Replace the solenoid valve with a new one.YES– The pulley-dephaser is faulty.
– Replace the pulley-dephaser with a new
one.
YES– The pulley-dephaser is faulty.

TEST 3 Camshaft dephaser solenoid valve
NOTESVdiag 54 only
Disconnect the solenoid valve connector.
Measure the electrical resistance between the
terminals of the solenoid valve at 20°C.
Is the electrical resistance of the solenoid valve
between 6.7 Ω and 7.7 Ω?
YES
Start the engine and set it to idle speed.
Run command AC254 Camshaft dephaser: ON/
OFF control (engine oil temperature between
10°C and 70°C).
Does the engine stall and/or is the idle speed
unstable?
NO
Switch off the engine.
Run command AC253: Camshaft dephaser:
Normal control
NOThe solenoid valve is faulty.
Replace the solenoid valve.
YESThe pulley-dephaser and the solenoid valve
are working.
Check the injection computer, the camshaft
sensor, the TDC sensor and their respective
wiring and connections.
