Circuit layout
The ignition system is integrated with theinjection and is of the inductive high efficiency type.
The controller manages two important parameters:
- Ignition advance
This is optimised according to the engine rpm,to the engine load, temperature and ambient pressure.
With idle engine, it is optimised to obtain thestabilisation of the speed at 1450 ?50 R/1'.
- Magnetisation time
The coil magnetisation time is controlled by thecontroller. The ignition power is increased during the engine start-up.
The injection system recognises the 4-strokecycle and therefore, ignition is only controlled during compression.
To check the ignition circuit, proceed asfollows:

- Connect the diagnostic tester dwg. 020460Y.
Select the menu on the "ACTIVE DIAGNOSIS"
function. Start the HV coil check with switch set
to "ON", switch to "RUN" and side stand raised.
Wait for the tester to display: "TEST
SUCCESSFUL"
YES
go to 3
NO
go to 2

- The tester displays: "TEST FAILED". Repeat the test and wait for the tester to display:
"TEST SUCCESSFUL"
YES
go to 3

- Select the menu on the "ERRORS" function. Check the presence of current or stored errors
relating to the H.V. coil.
YES
go to 6
NO
go to 5

- Test failed
YES

- The coil control circuit is efficient.
Check the H.V. coil secondary, the cable and the screened cap
6
- Install the specific tool dwg. 020481Y
between the injection system and the
controller.
Measure voltage between pins 20 and 23 of
the specific
tool during the fuel pump timing step.
To start the timing, set the switch to "ON" with
switch to "RUN" and side stand raised.
20 -23 = battery voltage (coupled to the pump
rotation -2 seconds).
If you want to increase the test time, enable
the "pump relay diagnosis" function
(30 seconds)
YES
go to 7
NO
go to 8

- The coil primary control circuit is efficient.
Carefully check the connectors to the controller and to the coil.
Replace the controller, if necessary.

Disconnect the connector to the H.V. coil
primary.
