WATER TEMPERATURE WARNING INDICATOR

RECOMMENDATIONS No failure must be present or memorized.

Check the mass presence on the indicator line, after control activating.
Mend if necessary

If a short-circuit has occurred at the supply circuit +12 volts on the indicator line, the instrument
panel may be damaged.

If the incident is persisting, consult the instrument panel diagnostic

Diagnostic – Parameters interpretation

RECOMMENDATIONS

Nothing to be noticed

Ensure that not the CLIP tester is the cause of the failure, by trying to communicate with the
computer of another vehicle.
Check connection between CLIP tester and the vehicle diagnostic socket (cable condition).
Check the condition of the injection fuses, engine and cockpit.
Mend if necessary.

Check the presence of the supply +12 V at pin 16 and of the mass at pins 4 and 5 of the diagnostic
device socket.
Mend if necessary.

Connect the 90 ways terminal box instead of the computer and check the insulation, continuity
and absence of the parasite resistance of the connections between:

pin 28 injection computer > mass

STARTING PROBLEMS engine is not starting or is difficulty starting)

RECOMMENDATIONS

Do not consult this diagnostic but before performing a complete
checking by means of the CLIP tester.

Check that starter is well operating

Check there is petrol in the fuel tank (fuel indicator failure).
Ensure that vehicle is supplied with adequate fuel.

Check that supply circuit hoses are not broken (especially further to a dismounting)
Check the condition of the fuel filter
Check the condition of the fuel tank
Check that fuel tank aeration is taking place.

Check the electric supply of the fuel pump.
Check the good operation of the choke sensor.

Check the motor of the idling regulator.
In order to unblock it, you may slightly hit it.

Disconnect the connection hose between the canister purging valve and the intake manifold.
Clamp the connection hose in order to stop the air passing.
If there are no more disturbances, the cause is the canister purging valve.

Check the spark plugs and ignition coil condition
Check that these elements are specific to that vehicle.

Check that the exhaust route is not clogged and the catalyst is not clogged.

Check the engine compressions

Check the flywheel condition

Check the distribution setting on.

AFTER

Perform a checking by means of the CLIP tester.
