NJECTOR
AND
CIRCUIT
When on the Dashboard Monitor page the Throttle Pos.
item displays an error, this meas that the electrical circuit
going from injector 1 or 2 to the ECU is interrupted; this
means that:
•
The internal circuit from the injector is interrupted:
replace the injector as described in chapter 6 of this
section;
•
The wires are cut-out: check the connections;
•
On the rare occasion that the circuit inside the ECU is
interrupted, replace the ECU as described in chapter
13 of this section.
When the motorbike has carburation problems, it is useful
to test the injection circuit; to do this, open the Active Test
page and, resting your ear against the faulty injector, click
the test key in the Injector icon: if you do not hear the
injector open and close and the test on the ECU gives a
positive result, this means that the injector is damaged
and must be replaced; if the test result is negative, go
back to one of the three above described cases.

IRCUIT AND PRIMARY WINDING OF COILS
When on the Dashboard Monitor page, the item Coil 1
or 2 displays an error, this means that the electrical circuit
going from coil 1 or 2 to the ECU is interrupted; this means
that:
•
The primary winding of the coil is interrupted or in
short circuit and it is necessary to replace the coil as
described in chapter 17 in this section;
•
If the wires are cut-out, check the connections;
•
On the rare occasion that the circuit inside the ECU is
interrupted, replace the ECU: replace the ECU
following the instructions described in chapter 13 in
this section.
When the motorbike has ingnition problems, it is useful
to test the circuit and primary winding of the coils; it is
therefore necessary to open the Active Test page, if the
test gives a positive result and the motorbike continues
to have problems, the defect is found upstream of the
primary.
In this case, in order to trace the faulty part, test the
following in sequence: the spark plug, the cap, the high
voltage wire, the secondary coil winding.
