SPS Circuit Open Test

If resistance in step 6) of ISOLATION TEST  was greater than 25 ohms, remove servo connector. Measure resistance between servo terminals "B" (Tan wire) and "D" Light Blue/Black wire). If resistance is greater than 25 ohms, replace servo. If resistance is now less than 25 ohms, check for open in circuit No. 399 (Light Blue/Black wire) between module terminal "H" and servo terminal "D". Check for open in circuit No. 398 (Tan wire) between module terminal "F" and servo terminal "B".
