Vac Circuit Open Test

If resistance in step 5) of ISOLATION TEST  was greater than 55 ohms, remove servo connector. Measure resistance between servo terminals "E" (Red wire) and "C" (Black wire). If resistance is greater than 55 ohms, replace servo. If resistance is less than 55 ohms, check for open in circuit No. 402 (Red wire) between module terminal "K" and servo terminal "E". Ensure servo terminal "C" connector is grounded.
