SELF-DIAGNOSIS DEVICE
When the key is turned to "ON", the tachometer and
speedometer needles should move to the maximum,
then back to zero. In addition all the warning lights and
the indicator lights should come on for a few seconds,
then go off. If the tachometer or speedometer needle
does not move as described or either of the warning
lights or indicator lights do not come on, check their
electrical circuits.
This model is equipped with a self-diagnosis device for
the following electrical circuits:
• speedometer
• tachometer
• throttle position sensor
• speed sensor
• ignition coil No. 1
• ignition coil No. 2
• fuel cut solenoid carburetor No. 1
• fuel cut solenoid carburetor No. 2.
If any of the above circuits are defective, the tachometer
needle will repeatedly signal a two digit error code (e.g.,
15, 16, 23, 24, 33, 34, 42).
If the tachometer needle signal such an error code, note
the circuit-specific number of r/min and check the oper-
ation of the system according to the following procedure.
0 / r/min (for 3 seconds)
0 / r/min (for 0.5 second)
Current engine speed
(for 3 seconds)
Indication of the r/min corresponding
to the first figure of error code
(for 2.5 seconds)

to the second figure of error code
