Test O: Servo Actuation Test

1. Check resistance between grounds G118 and G323.
2. If resistance is more than .1 ohm, clean and tighten both grounds and negative battery cable. If ground circuit is suspect, add a ground strap between engine block and bulkhead.
3. If resistance is less than .1 ohm, replace cruise control module and check for normal operation.


If all other tests under SYSTEM DIAGNOSTIC CHARTS were satisfactory, replace cruise control servo.
