Test No. 5

  1. Disconnect cruise control servo 10-pin connector. Turn ignition on. Using DVOM, measure voltage between terminals No. 1 (Orange/Light Blue wire) and No. 10 (Pink/Orange wire) of servo harness connector. See WIRING DIAGRAMS  . If voltage is approximately battery voltage, go to step 3). If voltage is not approximately battery voltage, go to next step.
  2. Using DVOM, measure resistance of Orange/Light Blue wire between terminal No. 1 of servo harness connector and terminal No. 4 of instrument cluster 16-pin connector C-214. See WIRING DIAGRAMS  . If resistance is less than one ohm, go to next step. If resistance is one ohm or more, repair open in Orange/Light Blue wire.
  3. Turn ignition on. Connect a jumper wire between terminals No. 1 (Orange/Light Blue wire) and No. 10 (Pink/Orange wire) of servo harness connector. See WIRING DIAGRAMS  .
