Test D

1. If measurement was less than 30 ohms, proceed to test J. Otherwise, remove connector from cruise control servo and measure resistance between terminals A and C of servo.
2. If resistance is greater than 55 ohms, replace cruise control servo.
3. If resistance is less than 55 ohms, check for open in dark blue/white wire (circuit 403, Lumina) or dark blue wire (circuit 403, Grand Prix and Regal) or light/green wire between terminal C of cruise control module and terminal A of cruise control servo. Ensure terminal C of cruise control servo connector is grounded.
