MEMORIZEDINFORMATION ROTATION SENSOR
1. Faulty cogs of the engine flywheel
2. Absence of flywheel signal.
In orde r to do this type of diagnosing, the sensor for atmospheric pressure
mu st not be faulty
Conditions of breakdown detection by the calculator:
-the contact is taken and the dialogue with the calculator is waited for to
be lo st, then the dialogue with the calculator is re-entered and the memo-
rized defec ts are erased
-opera te the starter for 10 seconds or start the engine and keep it in idle
m ode.
Condition of performing the diagnosing:
-defec t is present
-the defect has been memorized but is recorded in the “present” state.
Check the connection and the state of the rotation sensor
Change the connector if necessary.
Check the resistance of rotation sensor.
Remedy rotation sensor if necessary.
Connect the 90-way terminal-tester instead of the calculator and check the insulation, the
continuity and the absence of contact resistance along the circuits:
pin 54 of calculator
♦ pin A of rotation sensor
pin 24 of calculator
♦ pin B of ro tation sensor.
Remedy if necessary.
Check the condition of the cogs of the engine flywheel.
Change the rotation sensor if the incident persists.
The proble m is not yet solved! Consequently, the injection calculator must be changed.
CAUTION! The destruction of the calculator has probably been caused by an electric shock.
The cause of the destruction must be found before mounting a new
calcul ator.
Er ase defects memorized by the computer.
Perform the steps under “Suggestions” to confirm the repair.
Remedy other possible defects.

BRAKE FLUID
PERIODICITY OF THE BREAK FLUID CHANGE
The manufacturing conception of the brakes equipping the Dacia vehicles, especially
the di sks brake type (F 54 inner empty pistons, low qua ntity of fluid in t he c ylinders,
sliding calipers avoiding existence of a fl uid reserve in the less cooled area of t he wheel)
enable t he m aximum re jection of fluid vapori zation ri sk, even in c ase of intensive using of
brakes (mountain are a). The current bra ke fluids are subject in all cases to a slight degradation during the fi rst
months of use by a slight humidity absorpt ion seri es (see the Vehicle Warra nty and
Maintenance Booklet, for brake fluid change)
LEVEL COMPLETION
The wear of brakes pads and shoes generate a gradually diminution of brake fluid level
in its reservoi r. It is useless t o compensate t his diminution, because the level will be re -
stored in the moment of next changing the brake pads and shoes. Obviously, in the mean-
time, the level of brake fl uid in re servoir must not go down bellow the minimal mark.
HOMOLOGATED BRAKE FLUIDS
The mixture i n t he bra king circuit of two non compatible brake fluids may leads to loss
important risks mainly due to gasket damage
In order t o avoid such risks, it is obligatory t o use bra ke fluids checked and approved by
our laboratories and which are accordi ng to Norm SAEJ 1703, DOT 4.

OLLISION DIAGNOSIS
Du ring the vehicle exploitation, the carriage body may suffer different distortions, that
lead many times to the wheels setting angles change, body elements breakage, vibra tions
or even mechanical parts wear. In these conditions, be fore performing the vehicle body re paration, some checking is
necessary:
Visual checking - consisting in the e xamination of the mechanical elements attachments
and of the distortions occurring in the vehicle damaged areas.
Checking with the bar (control gauge) – consisting in comparing the measurements
done in symmetric points. The ge ometry checking of t he rol ling t ransmissions – this checking is t he only one
enabling to find out if the body damage was not affecting the vehicle road behavior.
IMP ORTANT
This checking must be not ignored, except some border-line cases, the checking of
the rolling transmissions leading to t he identification of the distortions occurred further
to an accident.

DASHBOARD
The dismounting of t he dashboard assembly is performed without t he dismounting of the
windscreen, the assembly being composed of :
- the upper part (A) where there are: the aeration grills of the windscreen (1); the aeration
grills of the lateral windows (2 ) ; the instrument panel; the lateral aerators and central aerator;
control and checking instruments;
- lower casing (B) containing :fuse box, front hood opening control (3), starter control
(choke ) (4), the adjustment handle of the steering wheel (5);
- central console (D) where there are mounted: the controls: climate system control(6), the
ash tray, the cigarette lighter, radio equipment and speed changer lever protector (7);
- the documents compartment (C ) .
