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.

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.
