Electrical System Check Out

  1. Check fuse and connector. Unplug electric brake switch connector at switch. Connect ohmmeter at the two terminals on brake switch. The ohmmeter must indicate infinity when the brake pedal is depressed, and continuity when the pedal is released. Replace switch if necessary.
  2. Unplug engagement switch connector at electrical wiring harness connector and perform the following tests (wire colors are the same in all models): 
  3. Connect ohmmeter between terminal No. 1 (brown wire) and terminal No. 2 (blue wire). Continuity should be maintained until switch is pressed all the way in.
  4. Connect ohmmeter between terminal No. 1 (brown wire) and terminal No. 3 (black wire). No continuity should be shown, however; when the button is depressed halfway, ohmmeter should show continuity. When the button is pressed all the way down, no continuity should be shown.
