Kawasaki Ninja Service Manual: Rear Wheel Rotation Sensor Signal (Service Code 24)

Kawasaki Ninja Service Manual / Self-Diagnosis System / Rear Wheel Rotation Sensor Signal (Service Code 24)

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] ← → KIBS Hydraulic Unit Connector [B] R/Y lead (ECU terminal 34, KIBS Hydraulic Unit terminal 16) [C]


Wiring Continuity Inspection KIBS Hydraulic Unit Connector [A] ← → Rear Wheel Rotation Sensor Connector [B] G lead (KIBS Hydraulic Unit Connector terminal 14) [C] R lead (KIBS Hydraulic Unit Connector terminal 13) [D]


Special Tool - Hand Tester: 57001-1394

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).

Fuel Injector Audible Inspection
NOTE Be sure the battery is fully charged. The secondary fuel injectors are operating with following conditions. 1. The engine speed is more than 6 000 r/min (rpm). 2. The throttle opening is more than 12В°. Remove: Fuel Tank (see Fuel Tank Removal) Primary Fuel Hose (see Fuel ...

Crankshaft Sensor Peak Voltage Inspection
NOTE Be sure the battery is fully charged. Using the peak voltage adapter [A] is more reliable way to determine the condition of the crankshaft sensor than crankshaft sensor internal resistance measurements. Disconnect the crankshaft sensor lead connector (see Crankshaft Sensor ...
