BATTERY VOLTAGE
NOTESThere must be no present or stored faults.
Without electrical consumers (radio, air conditioning, fan assemblies,
headlights, etc.).
Ignition on
Then at idle speed
If the voltage is at minimum:
Check the battery and the charging circuit (see Technical Note 6014A Checking the
charging circuit).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumer
(seeTechnical Note 6014A Checking the charging circuit).
AFTER REPAIRRepeat the conformity check from the start.

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.
