Brake Pedal Position Switch Signal: Civic

  1. Check brake lights. If brake lights are on without depressing brake pedal, check brake pedal position switch and adjust, repair or replace as necessary. If brake lights are not on, depress brake pedal. If brake lights come on, go to next step. If brake lights do not come on, go to step  3.
  2. Backprobing, measure voltage between PCM connector "A" (31-pin connector) "A" terminal No. 24 (Brown/Yellow wire) and PCM connector "E" (31-pin connector) terminal No. 22 (White/Black wire) with brake pedal depressed. See Figure. If battery voltage exists, problem is intermittent. Brake pedal position switch signal is okay at this time. If battery voltage does not exist, repair open in White/Black wire between brake pedal position switch and PCM connectors. See WIRING DIAGRAMS article.
  3. Check No. 7 (15-amp) fuse in underhood fuse/relay box. If fuse is okay, repair open in White/Green wire between brake pedal position switch and underhood fuse/relay box connectors. If fuse is not okay, repair short in White/Black wire between underhood fuse/relay box and PCM connectors. See WIRING DIAGRAMS article. Replace fuse.
