Idle Speed Control Valve Actuator Input Voltage Inspection


Special Tool - Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B

Idle Speed Control Valve Actuator Input Voltage Connections to Adapter: (I) Digital Meter (+) → R (actuator G/R) lead Digital Meter (–) → Battery (–) terminal (II) Digital Meter (+) → W (actuator G/O) lead Digital Meter (–) → Battery (–) terminal (III) Digital Meter (+) → Y (actuator G/Y) lead Digital Meter (–) → Battery (–) terminal (IV) Digital Meter (+) → BK (actuator G/BK) lead Digital Meter (–) → Battery (–) terminal

Idle Speed Control Valve Actuator Input Voltage Inspection


Input Voltage Standard: About DC 9 11 V and then
1 V or About DC 9 11 V


If the reading is out of the specification, remove the ECU and check the wiring for continuity between main harness connector.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and actuator connectors.
