  1. Turn ignition on. Disconnect cruise control servo 10-pin connector. With brake pedal released (not depressed), measure voltage between terminals No. 9 (Black/Yellow wire) and No. 10 (Pink/Orange wire) of servo harness connector. See WIRING DIAGRAMS  . If battery voltage is present, go to next step. If battery voltage is not present, go to TEST NO. 1.
  2. Leave ignition on. With brake pedal applied, measure voltage between terminals No. 9 (Black/Yellow wire) and No. 10 (Pink/Orange wire) of servo harness connector. See WIRING DIAGRAMS  . If voltage is less than 0.5 volt, go to next step. If voltage is 0.5 volt or more, replace deactivator switch.
  3. With brake pedal applied, measure voltage between terminals No. 4 (Tan/Light Blue wire) and No. 10 (Pink/Orange wire) of servo harness connector. See WIRING DIAGRAMS  . If battery voltage is present, go to next step. If battery voltage is not present, repair Brake ON/OFF (BOO) switch, blown 15-amp fuse No. 13 located in instrument panel fuse block, or open in Tan/Light Blue wire. Reconnect cruise control servo connector.
