Vent Circuit Short Test

If resistance in step 4) of ISOLATION TEST  was less than 30 ohms, remove servo connector. Measure resistance between servo terminals "A" (Dark Blue/White wire) and "C" (Black wire). If resistance is less than 30 ohms, replace servo. If resistance is greater than 30 ohms, check for short to ground in circuit No. 403 (Dark Blue/White wire) from module terminal "C" and servo terminal "A".
