Idle Air Control (IAC) Valve: Vitara
- Remove IAC valve electrical connector. Using DVOM, check resistance of IAC valve between terminals No. 1 and 2, 2 and 3, 4 and 5, and 5 and 6. Resistance should be 35-43 ohms between each set of terminals. If resistance is as specified, go to next step. If resistance is not as specified, replace IAC valve and retest system.
- Remove air cleaner hose and IAC valve. With electrical connector attached to IAC valve, crank engine for 2 seconds while observing valve. It should move once and then stop as soon as ignition is turned off. If IAC valve plunger does not move as specified, check for poor connections, open or short circuits in wiring. If electrical circuit is okay, replace IAC valve.
