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
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.
Wiring Continuity Inspection ECU Connector [A] ←→ Idle Speed Control Valve Actuator Connector [B] G/BK lead (ECU terminal 42) [C] G/Y lead (ECU terminal 43) [D] G/O lead (ECU terminal 44) [E] G/R lead (ECU terminal 56) [F]
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).

Storage of Removed Parts
After all the parts including subassembly parts have been
cleaned, store the parts in a clean area. Put a clean cloth
or plastic sheet over the parts to protect from any foreign
materials that may collect before re-assembly.
