Conditions for diagnostic appl ication to memorized failure:
Start t he e ngine a nd stop it immediately as the failure is oc curring as being
prese nt (risk for catalyst) or rota te de engine with the starter, without starting it,
for 10 seconds.
In case of failures addition, treat as most important, failure “ DF345 : Supply 5

if it is /they are present
* If the failure is memorized with OBD indicator on, check in the context part, if

lighting request is affirmative. In this case , proceed as per bellow mentioned
met hod
C heck the connection and condition of the coil connector .
R eplace the connector if necessary.
C heck the resistance of the coil resistance of c ylinders 1-4. Refer to chapte r
“Help” in order to compare the measured resistance values with the recommended
one .

Check the +12 Volts supply existence after fue l pump relay, at pin C of the coi l.
If it is necessary, apply the methodology for failure diagnostic “DF261”

The operation of the engine fan is controlled by the UCE injection, as follows:
1. For vehicles without air conditioning –cooling engine fan cooling is starting when water temperature is over 99°C;
– cooling engine fan cooling is stopping when water temperature is lower than 96°C.
2. For the vehicles with air conditioning. -cooling engine fan cooling is starting on first step when water temperature is over 99°C;
- cooling e ngine fan c ooling is start ing on second step when water temperature is over
104°C; - cooling engine fa n cooling is switching from second step to first step, when water
temperature is lower than 101°C; -engine fan cooling is stopping when water temperature is lower than 96°C.

Check fuse F01 from engine compartment. Is it good?
Replace water temperature sensor.
Replace the control relay of the cooling engine fan.
Replace the cooling engine fan assembly . Start the vehicle’s
engine.
Disconnect the water
temperature sensor. Is the
cooling engine fan working?
Check the control relay of the cooling engine fan Is it good?
Is any voltage between pins 1
and 2 of the cooling engine fan connector?
The wirin g

damaged. Fix it. Stop the vehicle engine.
Check the continuity and resistance
against vehicle mass between:
- pin B2 connector of water temperature sensor pin 13 UCE i njection;
- pin B1 connector of water temperature sensor pin 73 UCE i njection;
- pin 3 connector of cooling engine fan control relay exit fuse F01;

valve and the steering box.
Whe n dismounti ng, the high and low
p ressure pipes are to be positioned with the
connection screws downward oriented, i n
order to avoid contaminants penetration.

- wheels;
- battery.
Refill the circuit with oil ( full reservoir).
With stopped engine, easy a ct upon the
steering wheel in both directions, so that rack
is performing a complete double stroke.
Repeat the operation with started engine
(oil pump operatin g), then fill up to the MAXI
mark, the oil level in the reservoir.
Check and eventually adjust the
parallelism.
