Rear Wheel Rotation Sensor Signal Inspection
The rear wheel rotation sensor sends the signal to the ECU through the KIBS hydraulic unit (KIBS equipped models). For other than KIBS equipped models, the signal is sent directly to the ECU.
The ECU uses the rear wheel rotation sensor signal for motorcycle speed and S-KTRC control.
The service code 24 is detected with the ECU.

Rear Resistor Resistance (in Main Harness)
Connections:

R/Y lead (ECU terminal 34) [C]
Standard: 209
231 Ω

If the resistance is out of the standard, replace the main harness.
If the wiring and resistance are good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

Crankshaft Sensor Peak Voltage InspectionSport-kawasaki traction control (s-ktrc)
S-KTRC is an intelligent system that
calculates the slip level of the rear
wheel (wheelspin) and is suitable for
sports riding conditions. S-KTRC is
designed to function on public roads.
Acceleration may be delayed under
certain circumstances depending on
road conditions. S-KTRC cannot resp ...
System Components
1. KIBS ECU
With input from the front and rear wheel sensors and front
caliper hydraulic pressure, the KIBS ECU analyzes various
conditions on the motorcycle, and with additional information
from the FI ECU (engine speed, throttle position, gear
position, and clutch actuation) precisely control ...
Inner Tube Inspection
Visually inspect the inner tube [A].
If there is any damage, replace the inner tube. Since
damage to the inner tube damages the oil seal, replace
the oil seal whenever the inner tube is replaced.
NOTICE
If the inner tube is badly bent or creased, replace
it. Excessive bending, followed by ...
