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.

Overview
Mode-switchingKawasaki Intelligent anti-lock Brake System (KIBS,
For models equipped with KIBS)
KIBS regulates anti-lock braking performance
with more precision during
sports riding compared to a conventional
ABS system.
KIBS is designed to help prevent
the wheels from locking up when the
brakes are applied hard while riding
straight. KIBS automatically regulates
brake force using en ...
Spring Plate Free Play Measurement
Insufficient clutch free play will cause the engine braking
effect to be more sudden, resulting in rear wheel hop. On
the other hand, if the free play is excessive, the clutch lever
may feel “spongy” or pulsate when pulled.
Hold an extra drive shaft in a vise and install the following

ESD (Electronic Steering Damper) ECU Communication Error (Service Code 3C,
ZX1000JD/KD)
ESD ECU Communication Line Inspection
When the data (for status of ESD system) is not sent from
the ESD ECU to the meter unit and ECU, the service code
3C is displayed.
The data is sent through the CAN communication line.
The service code 3C is detected with the meter unit.
The FI symbol does ...
