Kawasaki Ninja Service Manual: Crankshaft Sensor Peak Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Crankshaft Sensor (Service Code 21) / Crankshaft Sensor Peak Voltage Inspection

Refer to the Crankshaft Sensor Peak Voltage Inspection in the Electrical System chapter.

If the reading is within the standard, remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

Crankshaft Sensor Peak Voltage Inspection

Disconnect the ECU and sensor connectors.

Wiring Continuity Inspection ECU Connector [A] ←→ Crankshaft Sensor Connector [B] BK lead (ECU terminal 8) [C] Y lead (ECU terminal 21) [D]

If the wiring is 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).

Seat Cutter Operation Care
1. This valve seat cutter is developed to grind the valve for repair. Therefore the cutter must not be used for other purposes than seat repair. 2. Do not drop or shock the valve seat cutter, or the diamond particles may fall off. 3. Do not fail to apply engine oil to the valve seat cutter ...

ESD Actuator Resistance Inspection
Turn the ignition switch to OFF. Remove the electronic steering damper unit (see Steering Damper Removal in the Steering chapter). Connect a digitalmeter to the ESD actuator connector [A]. Measure the ESD actuator resistance. ESD Actuator Resistance Connections: BK lead [1] ← ...

System Components
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 m ...
