2. Remove the switch screw (B,
Figure 108
) and
remove the switch from beneath the clutch lever.
3. Installation is the reverse of removal.
Front Brake Switch Replacement
The front brake light switch is mounted beneath
the front brake master cylinder.
1. Disconnect the spade connectors (A,
Figure
101
) from the front brake switch.
2. Remove the switch mounting screw (B,
Figure
101
) and remove the switch.
3. Installation is the reverse of removal. Check
switch operation. The rear brake light should come
on when the front brake lever is applied.
Rear Brake
Switch Replacement
The rear brake switch is mounted on the brake
pedal/footrest bracket.
1. Disconnect the two-pin rear brake switch con-
nector (A,
Figure 109
).
2. Disconnect the spring (B,
Figure 109
) from the
boss on the brake pedal.
3. Release the cable tie (C,
Figure 109
) and re-
move the switch (D) from its mount.
4. Installation is the reverse of removal.
a. Pack the connector with dielectric grease.
b. Secure the electrical cable with a new cable
tie (C,
Figure 109
).
5. Adjust the rear brake switch as described in
Chapter Three.
SELF-DIAGNOSTIC SYSTEM
All models are equipped with a self-diagnostic
system that checks the throttle position sensor and
the speed sensor. Whenever the main switch is
turned on, the engine indicator light on the meter as-
sembly turns on and the system runs a series of
checks. If the throttle position sensor and the speed
sensor are operating properly, the engine indicator
light goes out after approximately 1.4 seconds or
when the engine is started.
If the self-diagnostic system detects an error in ei-
ther component, the engine indicator light flashes
an error code after the initial 1.4-second period. The
engine indicator light flashes the error code, turns
off for three seconds, then repeats the error code.
The light continually flashes the error code until the
engine is started.
If an error is detected, the engine indicator light
remains on once the engine is running. To deter-
mine the code at this point, turn the engine off, then
turn the main switch on. Watch the engine indicator
light and count the number of flashes.
Three flashes (code 3) indicates a throttle posi-
tion sensor fault. Troubleshoot the TPS as described
in Chapter Eight.
Four flashes (code 4) indicates a speed sensor
fault. Troubleshoot the speed sensor by performing
the speed sensor test described in this chapter.
FUSES
Whenever a fuse blows, determine the reason for
the failure before replacing the fuse. Usually, the
trouble is a short in the wiring. This may be caused
by worn through insulation or a disconnected wire
shorting to ground.
