part of the car i n order to facilitate access to the screws fixing the starter; The screws fixing the command bar on the connecting rod of the gearbox are taken off
(the jack is retrieved);
The screws no. 1 fixing the start er are taken;
STA RTER
The car is suspended;
The electric connectors of the starter are disconnected;
The start er is taken out through the bottom of the engine compartment. R
E-MOUNT ING
The taking-apart opera tions are done in the reverse order.

IDLING REGIME ADJUSTMENT DUE TO BATTERY VOLTAGE
The idle mode of t he engine is influenced by the voltage of the battery with a view t o
compensating the voltage fa ll caused by the coupling of the consumers when the battery is
poorly charge d; this imposes an increase in the idle mode revolution ra tio, so the ratio of
the alternator will be incre ased by increasing the charging voltage. The lower the voltage,
the more significant the correction applied, which begins under 12.7 V.
The idle mode regime can thus be incre ased up to 830 rot/min.
If the injection calculator receives the information “command AC coupling”, then the
idle mode revolution ra tio will go up to 850 rot/min.

P
RINCIPL E:
In order to use the information related to the parameters value “PR 021= RCO idling“
and “ PR 022= RCO idling”, the CLIP tester is to be used, which will be connected at the
diagnosis socket and at the vehicle battery ( or lighter socket). Select on tester m enu “COMPUTERS TEST”, then “PETROL INJECTION” . Find then
“FUNCTIONS TEST” and read here the progress of the PR 021 and PR 022 parameters.
In normal operation conditions, warm engine, the value RCO idling ( PR 022 ) is changing
between a maximal a nd a minimal value, so that nominal idling RPM is obtained. It is
possible that further to an operation dispersion ( runni ng in, engine choking up,etc) the
value “RCO idling” to get closer t o the minimal or m aximal value. The adaptive correction (PR 021 ) on “ RCO idling” (PR 022) is allowing r eaching at slow
variations of the engine air necessities, so that “RCO idling” is re-set on an average nominal
value. The parameters PR 021 and PR 022 are progressing among the following limits :

INTRODUCTIONIn order to achieve the communication between the injection calculator
a nd the diagnosing tester SAGEM CLIP, the following operations will be
performed:
- the glove compartment is opened and the plastic shield of the diag-
nosing plug, located at the top of the compartment, is taken off; - the tester is connected at the diagnosing plug and across the termi-
nals of the car battery; - the type of the vehicle is selected on the tester;
- the option “Calculator test” is then selected;
- the menu “Injection” is selected.
CAUTION!
1. Connecting or disconnecting the injection calculator to the car cabling
wi ll only be done when the engine is stopped and the car is off-contact.
2. If the contact is on or the engine is running, the terminals of the battery
will no t be loosened or disconnected. Replacing the battery on the car is not
allowed if the engine is running or the contact is on.
3. Loose or oxidized contacts are not allowed at the terminals of the battery,
or im perfect connections at the injection system cabling.
4. Starting the en gi ne with the battery connected to a starting robot is not
allowed. 5. R echarging the batt ery will only be done after disconnecting it from the
car cabling, and it will be done using a 12V charging-station.

SUGGESTIONS
The contac

If the voltage < the minimal voltage, then the battery may be flat.
Check the charging circuit, in order to detect the cause of the problem.
If the voltage > the maximal voltage, then it is possible that the
battery may be overcharged.
Check the charging voltage to be correct, with and without consumers.
In idle mode
If the vo ltage < the minimal voltage, then the charging voltage is too
small.
Check the charging circuit, in order to detect the cause of the problem.
If th e voltage > the maximal voltage, then the charge of the battery is
too high.
The vo ltage regulator is faulty.
Remedy this problem, and then check the level of the electrolyte in the

GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. During the year it is recommended:
- the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

ITIONING UNIT
DISMOUNTING
Make the unit functioning for at least 10 minutes (if the unit permits).
Drain the circuit at the filling equipment.
Measure the quantity of recovered refrigerated fluid.
Release the access to the component that is needed to be changed.
Disconnect the connections.
In order to avoid the moisture infiltration, protect with protection covers.
Dismount the component.
REMOUNTING
P ut special c ompressor oil on the new elements thread and on the gaskets.
AT TENT ION
The new components must be obligatory provided with protection c overs.
Remove t he protection covers, connect the new component on t he free connection,
and tighten it by hand.
Place the component correctly.
Tighten it at couple.
Refill with refrigerant fluid and oil.
The filling up with oil for different repairs is to be performed as follows: add in the charging
equipment container, the recovered oil quantity, plus an oil quantity, as it follows:
- sudden damaged of one of the unit’s element or leakage 100ml
- condenser replacement 30 ml
- evaporator replacement 30 ml
- dryer filter replacement 15 ml
- pipe replacement 10 ml
For compressor dismounting/remounting without replacement add 120 ml.
If there are signs of moisture in the air conditioning circuit, replace the dryer filter tank.
