Test KE: Step 4
4) Measure ISC Solenoid Resistance Turn key off. Disconnect ISC solenoid. Set DVOM on 200-ohm scale, and measure resistance of ISC solenoid. Connect DVOM positive (+) lead to VPWR terminal and DVOM negative lead to ISC terminal as ISC solenoid is equipped with a diode. If resistance is between 7 and 13 ohms, go to next step. If resistance is less than 7 ohms or greater than 13 ohms, replace ISC solenoid and repeat QUICK TEST.
