PRELIMINARY OPERATIONS TO BE OBSERVED BEFORE
CHECKING THE STEERING ANGLES
1. Area (checking surface) – it must be a s horizontal as possible.
2. Wheels, tires – check (from e quipping point of vi ew) to have same type of wheels and
tires on bot h axles (dimensions, inflating pressure, wear de gree). A pronounced wear i s not
allowing the correct horizontal positioning.
3. Suspension – check the shock absorbers, springs condition and height symmetry under
carriage body.
4. Joints – check the e lastic joints condition, steering and suspension ball joints clearance,
bearings clearances of the front and rear axles 5. Radial and axial run out of the wheels – must not be over 1 mm. This will be compensated
with the reading instruments. 6. Manufacturer’s method – each vehicle manufacturer is providing the checking conditions,
axles weights repartition, and presentation of under carriage body heights, not loaded.

PURPOSE
To avoid the fire hazard due to the fuel losses, that may occur in case of an accident.
OPERATION
The hazard sensor ( 1) is placed in the engine compartment, being mounted on the left shock
absorber column.
In case of shock, the sensor ball l eaves its lodgement, t hus interrupting the electric c ircuit
between the control relay of the petrol electric fuel pump and the electric petrol pump.
HAZARD SENSOR RE-STARTING
The upper part of the hazard sensor is to be pushed to re-position the ball i nto its lodgement
and thus to re-start the sensor.

DISMOUNTIN G
Place the vehicle on a two-column elevator
Disconnect the battery
Dismount the alternator upper attachment screw.
Dismount the front right wheel.
Lift the vehicle.
Dismo unt :
- protection fairing;
- lateral tie-rod ( 1);
-s hock absorber two attachment screws (2) on steering knuckle.
Swing over the steering knuckle and remove the right planetary transmission from the plan-
etary gear of the gearbox. Disconnect the electric connectors of the alternator.
Dismount the alternator lower attachment screw.
Dismount the alternator’s belt.
Remove the alternator, laterally by the right planetary transmission.
REMARK:
In order to replace the alternator belt, first dismount the accessories driving belt
(compressor and/or power steering pump).
R EMOU NT I NG
Perform the dismounting operations in the reverse order.
Tighten the alternator driving belt to 263 HZ ± 10% by means of the MOT 1505 device (see
the m ethod described in c hapter 07 “ Accessories belts tightening”)
Tighten to the required moment the alternator’s attachment screws.
REMARK:
A dismounted belt is not to be remounted, but replaced.

DIAGNOSTIC
Special tool : CLIP tester – TECHNIC for measuring the battery voltage and the absorbed
intensity in the starting stage.
OPERATION ABNORMALITIES THAT MIGHT BE NOTICED
- Battery failure = large voltage drop on starter during engine starting stage.
- Blocked starter = the absorbed current is very high.
- Solenoid failure = the absorbed current is very low.
In order to perform the measurements, it is necessary the engine drive by means of the starter,
but stopping the engine starting.
To do that, disconnect the RPM sensor (located on clutch casing).
REMARK:
After performing this checking, erase by means of the CLIP tester, the possible failures
memorized by the computer.

AIR CONDITIONING UNIT IS USING A COMPRESSOR
WITH VARIAB LE DI SPLACE M ENT
Th e connections injection/air conditioning, are the followings:
- pin 46 of the injection computer is receiving the information “ air conditioning
re que st” further to the air conditioning switch acting;
- pin 10 of the injection computer will transmit the coupling control of the air
co nditioning compressor by means of the “A” relay, if the coupling authorization conditions are
accomplished.
The information “power absorbed by compressor” displayed when performing diagnostic by
means of the CLIP tester, is related to the couple value taken by the compressor. This is of 300-
5000W, the minimal displayed value being of 300 W, regardless the compressor coupled / unc oupled
c ondition.
Th e injection computer is forbidding the compressor coupling in the following situations:
-at less than 16 seconds from engine starting;
-subject to the power requested to the engine by the vehicle driver.
-when th e acceleration pedal is fully pressed;
-i f the engine RPM is lowering till 550 rot/min (compressor is again coupling if the RPM is
r eachi ng to 1800 rot/min);
-if the wa ter temperature has increased to over 110° C;
-if the engi ne RPM is exceeding 6000 rot/min.

The purpose of the catalyst diagnostic is the detection of the disturbances leading to exceeding
an OBD step due to HC pollution emissions.
Th e ca talyst storage capacity of the oxygen is the indicator of its condition. When the catalyst is
beginnin g to ”age”, the storage capacity of the oxygen is diminishing, in the same time with the
dimin ishing of the treatment capacity of the pollution gases.
IMPOSED CONDITIONS FOR DIAGNOSTIC STARTING
Th e ca talyst diagnostic can be not performed but after a certain time of engine operation and
on ly if the preliminary conditions, when setting the contact on, are accomplished and preserved:
-no electr ic failure
-c ylinder’s recognition performed
-n o detected combustion misfire.
-n on-performing of the catalyst diagnostic after contact setting on.
-correct performing of the “learnings” by the UCE injection.
-water temper ature to be over 75°C

FAILURES DETECT ION
Th e diagnostic is to be performed on a stabilized range in the fifth gear, at the speed of 70 Km/h.
When the diagnostic starting conditions are accomplished, excitation peaks are applied, which is
le ad ing to th e oxygen bubbles sending to the catalyst. If the catalyst is good, it w ill absorb the
ox ygen and the tension of the downstream oxygen sensor will remain at an average value. If the
catalyst is used, it will reject the oxygen and the oxygen sensor will wrongly define the phenom-
en on. The oxygen sensor tension will fluctuate. If the failures is three consecutively times con-
firmed, th e OBD indicator would be on.
Th e test duration will be not exceeding 52 seconds.
ATTENTION: after performing this tes t, the contact s etting on is imposed (key in M
position) before reading the res ults by means of the C LIP tester. Any contact sett ing off
be fore reading the test results, will lead to their wrong interpretation.
If after test performing, the CLIP tester is noticing the presence of the combustion mis-
f ires, refer to the diagnostic method related to this symptom.
