1993 Suzuki Sidekick JS, 4D UtilityFACTORY OEM SERVICE PROCEDURE
Idle Air Control (IAC) Solenoid
- Turn ignition off. Disconnect electrical connector from IAC solenoid. Check resistance between IAC solenoid terminals. On Samurai and Swift, resistance should be 30-33 ohms at 68 °F (20 °C). On Sidekick, resistance should be 11-14 ohms at 68 °F (20 °C). Replace IAC solenoid if defective.
- If reading is okay, disconnect IAC solenoid air hose from air intake case. It should be difficult to blow air into hose. If resistance is felt, connect battery voltage to IAC solenoid valve terminals. If it is still difficult to blow air through valve, replace IAC solenoid valve. Reinstall hose and connector securely.
