Brake Switch A Circuit

43 brands affected · Generic SAE J2012 description.

Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to the braking system. Have braking checked promptly.

1What it means in plain English

The brake pedal switch signal is not what the engine computer expects. This switch tells the car when the brakes are applied and also controls the brake lights, cruise control and, on some cars, starting.

2Common causes

  1. Faulty or misadjusted brake light switch
  2. Blown brake-light fuse
  3. Damaged wiring or connector
  4. Brake pedal travel or pedal stop problem
  5. Faulty body or engine control module

3Can I drive?

Caution · drive with care

Have it checked promptly: the brake lights may not work, which is dangerous, and on some cars the car may not start or may not shift out of park. If the brake lights do not come on, do not drive; otherwise drive carefully to a workshop.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
