Speed Control Servo

  1. Start engine. Disconnect Speed Control (S/C) servo 4-pin connector. Turn speed control switch to ON position. Using a voltmeter, check voltage at S/C servo connector terminal No. 3 (Dark Blue/Red wire). Battery voltage should exist when brake pedal is not depressed.
  2. Connect a jumper wire between S/C servo pin No. 3 and S/C servo connector terminal No. 3. Check voltage at S/C servo pins No. 1, 2 and 4. If battery voltage does not exist, replace S/C servo.
  3. Turn ignition off. Check for continuity between S/C servo connector terminal No. 4 and ground. Continuity should exist. Repair open ground circuit as necessary.
