1. FI ECU
The FI ECU analyzes the motorcycle conditions based on the signals from the front/rear wheel rotation sensors and FI sensors (such as the crankshaft sensor and main throttle sensor), and controls engine power by reducing the number of ignition and retarding the ignition timing. The mode-switching signal is transmitted to the FI ECU by the CAN system via the meter ECU. If a failure occurs in the system, the FI ECU deactivates S-KTRC and displays the warning indication in the meter.
2. Wheel Rotation Sensor
The wheel rotation sensor converts front and rear wheel rotation speed to a pulse signal and transmits it to the FI ECU.
As for the KIBS (Kawasaki Intelligent anti-lock Brake System) equipped model, a pulse signal is transmitted via the KIBS ECU.
3. Crankshaft Sensor
The crankshaft sensor converts the engine speed to a pulse signal and transmits it to the FI ECU.
4. Main Throttle Sensor
The main throttle sensor converts the throttle position to a voltage signal and transmits it to the FI ECU.
5. S-KTRC Button
The mode-switching signal is transmitted to the meter
ECU by depressing the S-KTRC button (0.3
0.4 sec.).
6. Multifunction Meter
The multifunction meter receives a mode-switching signal and displays the mode [A], and transmits it to the FI ECU by the CAN system.
When a failure occurs in the system, themultifunction meter displays the warning indication by blinking the warning indicator light (yellow LED) [B] and mode indicator symbol.
It also displays the S-KTRC operating conditions in the level indicator [C].
7. KIBS ECU
As for the KIBS equipped model, the front and rear wheel sensor signals are transmitted to the FI ECU via the KIBS ECU.

ABS Indicator Light (For models equipped with KIBS)
: Normally
the ABS indicator light goes on when the ignition switch is turned
“ON” and goes off shortly after the motorcycle starts moving. If the ABS is
normal,
it stays off. If the ABS indicator light shows any of the following, a fault or
faults may
have taken place in the ABS. You ...
Tachometer
The tachometer shows the engine
speed in revolutions per minute (r/min,
rpm).
On the right side of the tachometer
face is a portion called the “red zone”.
Engine r/min (rpm) in the red zone is
above maximum recommended engine
speed and is also above the range for
good performance.
