Code A094 - Brake Switch Contacts Always Closed: Notes

This test 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 will result in a dead battery.

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. This step determines if fault is still present.
  2. This test isolates fault to either a faulty or misadjusted brake switch or a short to battery in brake switch circuit.
