24
The motorcycle has overturned.
30
The amount of air-fuel ratio feedback
compensation is maintained continu-
ously in the vicinity of the upper limit
31
(lean air-fuel ratio).
The amount of air-fuel ratio feedback
compensation is maintained continu-
ously in the vicinity of the lower limit
32
(rich air-fuel ratio).
Open circuit is detected in the primary
wire of the ignition coil (#1, 4).
33
Open circuit is detected in the primary
wire of the ignition coil (#2, 3).
34
Lean angle cut-off switch - open or
41 short circuit detected.
No normal signals are received from
the speed sensor; or, an open or
short circuit is detected in the neutral
42
switch.
The ECU is unable to monitor the bat-
43 tery voltage (an open circuit in the
monitor line to the ECU).
An error is detected while reading or
44
writing on EEPROM.
Faulty ECU memory. When this mal-
50 function is detected, the code number
might not appear on the meter.
