IGNITION AND INJECTION

This diagnostic may detect:
-spark plug fouling or smoking,
-fou ling or modification from the normal value of the injectors flow,
-f uel supply system abnormalities (pressure controller, fuel pump,..)
-pr oblems with the electric connections for controlling fuel supply circuits and the injection.
Th e di ag nostic is performed by variations measurement of the engine prompt rotation speed.
Notice of a couple decrease is allowing the defective combustion recognition as failure cause.
Th is diagnostic is done almost permanently during driving. Non accomplishment of the diagnos-
tic or recognition of the existence of failure, is leading to other OBD diagnostics inhibition. This diagnostic is enabling the identification of two types of failures:
-de structive combustion misfires, which are causing the catalyst damage. These are gener-
ating the immediate blinking of the OBD indicator. -Polluting combustion misfires, leading to e xceeding a pre-established OBD pollution limit.
These ar e generating the permanent lighting of the OBD indicator, if the cause detection is
taken place during three consecutive running.
DE T ECT ION CONDITIONS
At the beginning, it must be checked if the “learning” stages of the adaptive values by the UCE
injection have been correctly performed. Also the preliminary conditions imposed when setting the
co ntact on and those from checking moment, must be accomplished.
Check by means of the CLIP tester if the bellow mentioned states are in the following configu-
ration:
ET0 14 Cylinder 1 recognition----------------------------------------------------------------- DONE
ET2 02 OBD diagnostic of combustion misfires taken into consideration--------------AC TIVE
Detection is accomplished after the water temperature is exceeding 75°C, at three rotation
steps, between idling and 4500 rot/min. It is also possible, test performing by maintaining the engine
at idling for a period of time of 11 minutes.
ATTENTION: after performing this test, the contact set ting on is imposed (key in M
position) before reading the r esults by means of the CLI P t ester. Any contact set ting 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.
CONFIRM ATION OF THE RE PARATION PE RFORM ING
-Check by m eans of the CLIP tester, the bellow states, which must have the following
c onfiguration:
ET0 14 Cylinder 1 recognition -------------------------------------------------------------------- DONE
ET2 02 OBD diagnostic of combustion misfires taken into consideration ----------------- AC TIVE
-N o failures is detected by the CLIP tester, and the OBD indicator must be off.

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
