• How to erase the self-diagnostic fault code from memory:
If the ECU detects a normal signal upon the completion of the repair of the malfunction, the self-
diagnostic fault code disappears from the meter and is replaced by the normal clock display. How-
ever, the self-diagnostic fault code of the previous malfunction remains in the ECU memory as
part of the malfunction history. To erase the self-diagnostic fault code from the malfunction history,
the operation for diagnostic code 62 must be performed in the diagnosis mode.

Symptom
The motorcycle has overturned.
The amount of air-fuel ratio feed-
back compensation is maintained
continuously in the vicinity of the
upper limit (lean air-fuel ratio).
The amount of air-fuel ratio feed-
back compensation is maintained
continuously in the vicinity of the
lower limit (rich air-fuel ratio).
Open circuit detected in the pri-
mary wire of the ignition coil
(#1,4).
Open circuit detected in the pri-
mary wire of the ignition coil (#2, 3).
Lean angle cut-off switch - open
or short circuit detected.
No normal signals are received
from the speed sensor; or, an
open or short circuit is detected in
the neutral switch.
The ECU is unable to monitor the
battery voltage (an open circuit in
the line to the ECU).
An error is detected while reading
or writing on EEPROM (CO
adjustment value).
Faulty ECU memory. When this
malfunction is detected, the code
number might not appear on the
meter.
