ANTI-STARTING INDICATOR
When setting the contact on, UCE injection is receiving from UCE DECODER a code, whi
ch is compared
with the one previously memorized; if the two codes are matching, then the engine starting is author ized.
After contact setting on, anti-starting indicator which was previously blinking, will light for
three seconds then it will go off, confirming in this way, the key recognizing.
If the key is not good, after setting on the contact, the anti-starting indicator will start blinking
faster and the engine starting will be impossible.
OBSERVATION:
For details regarding the vehicle anti-starting system, see chapter 82 “Anti-starting system”.
AT T E N T I ON!
U CE injection c onnecting or disconnecting to t he vehicle’s wiring i s to be pe rformed
Injection system
only when the engine is stopped and t he contact off.
If the contact is on or the engine is running, do not loosen or disconnect the battery
terminal s. It is forbidden the battery replacement on t he vehicle i f the engine is running
or the contact on. Loosen or rusty contacts at battery terminals and imperfect connections at the
injection system wiring are not allowed. It is forbidden the engine starting with the battery connected to a charging / starting
unit. The battery recharging is t o be pe rformed only aft er disconnecting it from the vehicle
wiring and by means of a c harging unit with 12 V v oltage.

Before perform this checking, check the lines corresponde nce on the
electric diagram adequate to that vehic le.
Ch eck that choke sensor is in operating condition
M end the choke sensor if necessa ry.
Ch eck the continuity between ways 1 and 3 of the choke sensor.
If there is no continuity, repla ce the choke sensor.
Ch eck, under starter operation, the prese nce of the +12 volts at way 3 of t he choke sensor connector.
If there is no +12 volts, restore in function the line from way 3 of the choke sensor to pole 5 of the fuel
pump relay.
Ch eck the wiring condition and the mass presence at the fuel pump.
