INJECTION - AIR INTAKE SYSTEM
“C24” OR “C25” IGNITION SYSTEM MALFUNCTION (see page G24)
“C31” GEARCHANGE SENSOR CIRCUIT MALFUNCTION
PROBLEM POSSIBLE CAUSE
Gearchange position switch voltage not present
Low switch voltage
(Switch voltage
>
0,6 V)
outside the indicated range.
• Gearchange position switch circuit open or in short-
circuit.
• Gearchange position switch malfunction.
• ECM malfunction.
CHECK
1
Turn the ignition switch to the OFF position.
Check to see if the connector contacts of the GP switch are
loose or ruined.
If OK, measure the voltage of the GP switch.
Lift up the machine on a suitable support.
Lift up the side stand.
Turn the engine kill switch to the ON position.
Turn the ignition switch to the ON position.
Measure the voltage at the wiring connector between the red
lead and Earth, changing from 1st to 6th gear.
GP switch resistance: More than 0.6V
(Orange/yellow- Earth)
Tester dial indication: Voltage ( — )
NO Red lead circuit open or in short-
circuit.
Substitute the GP switch.
YES
Orange/yellow lead circuit open or in short-circuit to Earth. Or con-
tact 18 ruined.
If the leads and connections are OK, the problem is intermittent or
the ECM is defective.
Recheck each terminal and wiring for open circuits or ruined con-
nections. (see page C-6).
Substitute the ECM and recheck.
