If the problem is persisting after these checking, fix the other failures the n perform the conformity
checking.
If failure “DF345 : Supply 5 volts potentiometers or transducers” is present
or memorized, this must be treated with priority.
Conditions for failure detection by the compu ter:
- Set the contact on
- If the failure is only memorized, st art the engine in order to obtain a temperature
variation (an engine cooling fan starting).
(The failure must pass to the present state, but i t may become again memorized
imme diately after finishing performing the previous operations).
* If the failure is memorized with OBD indicator on, check in the context part,
if state “ET275 : Water temperature sensor circuit” c orresponding to the
OBD indicator lighting request is affirma tive. In this case, proceed a s per
bellow mentioned method.
P erform the operations from “recommendations” for reparation confirmation.
Fix a ny other possible failures.
Erase the failures memoriz ed by the injection computer.
Perform a conformity checking by means of the CLIP tester.

Ch eck for leakage on exhaust line.

Pe rform a visual checking of the catalyst condition. O deforma tion may be the explanation for its
non-operation.
Ch eck if the catalyst has not previously suffered therma l shocks.
If cold wate r is getting on a warm catalyst it may cause its damaging.
Ch eck for oil or cooling fluid excessive consumption Ask the client if he has used an additive or a
sim ilar product. This type of product may inhibit the catalyst and render it inefficient on short or
l ong term.
Ch eck if there was any combustion misfires. These may damage the catalyst.
Ch eck during a drive test for any noises during running.
If the damaging cause has been found, you may replace the catalyst. If you replace the catalyst
without det ecting the cause, the new catalyst may be damaged al so very qui ckly.

COOLING - EXHAUST - TANK
The heating radiator has no valve.
The fluid circ ulation is permanently done in the heating radiator, this leading to t he engine
cooling.
FILLING
Open the purging screw located on the water pipe between engine and climate control radiator.
Fill up the circuit by the expansion vessel hole
Tighten the purging screws in the moment when the fluid is flowing in a continuos jet.
Start the engine, maintaining it at 2500 rot/min.
Adjust the fluid level in the expansion vessel, during about 4 minutes.
Close the cap of the expansion vessel.
PURGING
Let the engine run for 10 minutes at 2500 rot/min, until engine fan starting (necessary
period for automatic gas purge).
Check if the fluid level in the expansion vessel is nearby the mark “Max”.
Do not open the purging screws with the engine running.
Ret ighten the expansion vessel cap with the warm e ngine.

1. CIRCUIT S EALIN G CHECKING
Mount the adapter M.S 554 –01 instead of
the expansion vessel valve.
Connect a t the adapter, the M.S. 554-07
device. Wa rm the engine, then stop it.
P ump, in order to create pressure in the cir-
cuit. Stop pumping at a value lower with 0.1 bar
then the valve calibrating value ( 1.2 bar)
The pressure must not drop, if not, check for
leak and fix it.
Progressively unscrew the device connection
for cooling circuit decompressing , then unscrew
the device, and mount back the expansion vessel
valve.
2. CHECKING ALVE CALIBRATION
M ount t he expansion vessel va lve on
adapter M.S. 554-06 and connect it to the
MS 557-07 device.
P ump to increase the pressure, this must
be stabilized at the valve calibration value 1.2
w ith a checking tolerance of ± 0.1 bar.
The calibra tion value of t he expansion
vessel valve is : 1.2 bar.

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
