Vent Circuit Open Test

If resistance is less than 30 ohms, go to VENT CIRCUIT SHORT TEST  . If resistance is greater than 30 ohms, remove servo connector. Measure resistance between servo terminals "A" and "C". If resistance is greater than 55 ohms, replace servo. If resistance is less than 55 ohms, check for open in circuit No. 403 (Dark Blue) wire between module terminal "C" and servo terminal "A". Ensure servo terminal "C" connector is grounded.
