  3. Replacing blown fuses.
  4. Replacing faulty cruise control modules (rare)

What is a po573 code?

P0573 is a diagnostic trouble code (DTC) for “Cruise Control/Brake Switch A Circuit High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What does a cruise control release switch do?

The cruise control brake release switch is a switch that turns off your cruise control when your brake pedal is pressed. When you decelerate your vehicle while cruise control is turned on the cruise control module detects a loss of continuity and cancels the cruise control set speed.

What is the brake switch?

A brake light switch is an electrical switch that turns your brake lights on when you hit the brakes. It’s an integral part of your braking system and lets the driver behind you know that you’re slowing down. It also has a direct influence on your ABS, cruise control system, and more.

What does brake switch a circuit low mean?

Error Code P0572 is defined as Cruise Control/Brake Switch A Circuit Low, meaning there’s a malfunction detected within the cruise control system or brake switch of the vehicle, often caused by faulty or damaged wires. There are many factors that can alter the speed of the vehicle while driving down the road.

What is brake switch circuit?

brake light switch
The brake switch (or brake light switch) is a switch linked to the brake pedal and ECM circuit. It’s mounted on the brake pedal arm. It deactivates cruise control while driving and lets the engine start when the brake pedal is depressed.

Does cruise control ruin brakes?

In short, no—cruise control is not bad for your car. Most models rely on engine braking—downshifting to reduce speed—when going downhill. Engine braking doesn’t hurt your vehicle. The problem is when you set the cruise control and proceed to navigate steep hills or winding roads.

How do I know if my cruise control module is bad?

Symptoms of a Bad or Failing Cruise Control Vacuum Bleed Switch

  1. Cruise control does not disengage when pedal is pressed.
  2. Cruise control disengages on its own intermittently.
  3. Hissing noise coming from under the dash.

Where is the brake relay switch located?

The switch is located right near the tip of your right foot near the brake pedal, so it’s easy to access. The switch may actually snap into place without the use of any tools at all. $20-50 dollars should cover the labor costs on most cars.

How does the p0573 brake switch code work?

P0573 code gets stored once your vehicle’s PCM senses an abnormal resistance/voltage level in the cruise control brake switch circuit during this test. That feedback essentially tells it speed cannot be controlled and thus cruise control must be prohibited.

What does the p0573 code on a PCM mean?

P0573 code definition. When the PCM stores the P0573 code, it’s because it has discovered an electrical malfunction affecting your vehicle’s cruise control brake switch “A” circuit.

What does the stop light signal p0573 mean?

When the brake pedal is depressed, the stop light switch sends a signal to the Engine Control Module ( ECM ). When the ECM receives this signal, it cancels the cruise control. Need more information on how to fix the P0573 code?

What causes a p0573 cruise control code to be high?

Causes for this P0573 cruise control code may include: Cruise control/Brake switch defective Wiring issue (e.g. pinched on brake pedal, chafed, etc.) ECM (engine control module) issue (i.e. internal short, open, etc.) Debris/dirt mechanically hindering brake switch operation Brake switch not adjusted properly
