NOTE
Before this inspection, confirm the pulley is original position (see Exhaust Butterfly Valve Actuator Installation).
Special Tool - Throttle Sensor Setting Adapter #1: 57001 -1400
Exhaust Butterfly Valve Actuator Sensor Output Voltage Connections to Adapter: Digital Meter (+) → BL (actuator Y) lead Digital Meter (−) → BK/BL (actuator BK) lead
Output Voltage
Standard: DC 3.46 3.76 V at pulley
original position
If the reading is out of the standard, check the exhaust butterfly valve actuator sensor resistance (see Exhaust Butterfly Valve Actuator Sensor Resistance Inspection).
If the reading is within the standard, remove the ECU and check the wiring for continuity between main harness connectors.
Disconnect the ECU and sensor connectors
Wiring Inspection ECU Connector [A] ←→ Exhaust Butterfly Valve Actuator Sensor Connector [B] GY lead (ECU terminal 24) [C] BR/BK lead (ECU terminal 13) [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).

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 ...
