- camshaft gear (t o be blocked by
means of MOT 799-01 device);
- camshaft;
- thermostat support;
- spark plugs;

It is very important not to scratch the
cylinder head on gasket seating face.
The Decapjoint product is to be used
for removing the remaining gasket stacked
pieces.
Apply the produc t on the area to be
cleaned, wait for about 10 minutes, and then
clean with a wooden spatula. During this operation protection gloves are
to be used.

IGNITION AND INJECTION

PRESENTATION
The system is composed of : -electronic control unit (UCE injection);
-a double ignition coil;
-f our spark plugs;
- spark plugs cables.
OPERATING PRINCIPLE
Subject to the information received from different sensors, but mainly subject to engine RPM
and charge, the electronic control unit will establish the advance at ignition, will identify the cylinders
being at upper dead point and consequently , will control the corresponding coil to them.
This is producing the spark at the level of the two cylinders being at upper de ad point,
interrupting the mass connection of the corresponding coil.

1 10 CONTINUA TION
Ensure that all failures are solved. Erase all memorized failures.
There is no need to erase the “adaptive values” memoriz ed by the injection computer.
In order to check the correct reparation of the system, the following conditions must be
AF TER accomplished:
REPARATION - No more electrical failures;
- All “adaptive values” to be memorized by the injection computer;
- Warm engine (minimum 75°C);
- Run at idling, all consumers being in use for 20 minutes (1 minute DF110);
- If the failure is again occurring, repeat the dia gnostic.
