ON-VEHICLE INSPECTION





1. INSPECT IAC VALVE FOR OPERATING SOUND
Check that there is a clicking sound immediately after stopping the engine.
If operation is not as specified, check the AC valve, wiring and ECM.








2. INSPECT IAC VALVE RESISTANCE

NOTICE: "Cold" and "Hot" in these sentences express the temperature of the coils themselves.
"Cold" is from -10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to l00°C (212°F).
Using an ohmmeter, measure the resistance between the terminals (B1 (or B2) to others).
