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.

Wiring Continuity Inspection ECU Connector [A] ← → Rear Wheel Rotation Sensor Connector [B] R lead (ECU terminal 58) [C] R/Y lead (ECU terminal 34) [D]
Rear Resistor Resistance (in Main Harness) Connections: ECU Connector [A] ← → Ground [B] 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).

Front and Rear Brakes
Disc and disc pad wear is automatically
compensated for and has no effect
on the brake lever or pedal action.
So there are no parts that require adjustment
on the front and rear brakes.
WARNINGAir in the brake lines diminish
braking performance and can
cause an accident resulting ...
