Kawasaki Ninja Service Manual / Self-Diagnosis System / Exhaust Butterfly Valve Actuator (Service Code 63) / Exhaust Butterfly Valve Actuator Resistance Inspection

Turn the ignition switch to OFF.
Disconnect the exhaust butterfly valve actuator lead connector (2 pins connector) [A].
Set the hand tester to the × 1 Ω range and connect it to the exhaust butterfly valve actuator connector.

Special Tool - Hand Tester: 57001-1394

Measure the exhaust butterfly valve actuator resistance.

Exhaust Butterfly Valve Actuator Resistance Connections: P lead ←→ GY lead Standard: 5 200 Ω (for reference)

If the reading is 0 or infinity (∞) Ω, replace the exhaust butterfly valve actuator.

If the reading is in specification, remove the ECU and check the wiring for continuity between main harness connectors.

Disconnect the ECU and actuator connectors.
