NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Statuses ET704 and ET705 should change status at the same time. If they are inconsistent, consult the
interpretation of fault DF228 Brake signal.
ACTIVE
or
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
Brake light switch, track 3 Injection computer, connector A,
black, 32-track track E4
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
Continuity between
tracksInsulation between
tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(brake pedal pressed)1 and 2 3 and 4
Replace the switch if the values obtained are not correct.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

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.

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.

ALP 2 The engine will not start
NOTESFollow ALP 2 after a complete check with the diagnostic tool.
WARNING
Never drive the vehicle without checking first that there are no throttle valve
faults.
If the starter motor does not engage, there may be an engine immobiliser fault.
Carry out fault finding on the UCH (see87B, Passenger Compartment Connection Unit).
Check the condition of the battery.
Check the cleanliness, condition and tightness of the battery terminals.
Check that the battery is correctly earthed to the vehicle bodywork.
Check that the + battery leads are correctly connected.
Check that the starter motor is properly connected.
Check the starter is working properly (see Technical Note 6014A Checking the charging circuit).
Check the condition and conformity of the spark plugs.
Check the mounting, cleanliness and condition of the flywheel signal sensor.
Check the flywheel signal sensor air gap.
Check the condition of the flywheel.
Check that the air filter is not clogged.
Check that the air inlet circuit is not blocked.
Check that there is fuel in the tank (fuel sender fault).
Check that the tank vent is not blocked.
Check that the fuel is of the correct type.
Check that there are no leaks in the fuel system, from the tank to the injectors.
Check that there are no kinked hoses (especially after a removal operation).
Check the fuel flow rate and pressure.
Check the sealing of the injectors, and that they are working properly.
Check that the exhaust system is not blocked and the catalytic converter not clogged.
Check the timing setting.
Check the cylinder compressions.
Check the hydraulic tappets if there is camshaft noise.
AFTER REPAIRRepeat the conformity check from the start.
