Code A094, Brake Switch Contacts Always Closed: Notes

This code is run to determine proper operation of brake switch. This is important because ABS is activated when brake switch is on, and turned off when brake switch is off. If brake switch is always on, ABS operation will always be requested, resulting in potential modulator cycling on rough roads. This failure may result in a dead battery from brake lights being on continuously.

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. Determines if fault is still present.
  2. Isolates fault to either a faulty or misadjusted brake switch, or a short to battery voltage in brake switch circuit.
