What is the fault code P0571? What is the definition of Cruise Control/Brake Switch A Circuit Malfunction How do you fix P0571 fault code? What are the causes of P0571?
What is the P0571 fault code? What does it all mean?
The cruise control system must work properly if the brake switch is to be pressed. To turn the cruise control on or off, press the brake pedal. If the powertrain controller module (PCM), detects a fault with the brake light switch, or circuit “A”, a P0571 code will be saved. The code’s description could refer to a specific component, cable, connector or circuit. To determine the code, you should consult the manufacturer’s service manual.
P0571 fault codes can be found on many vehicles, including Dodge, Jeep and Mazda, Duramax and Opel models.
What causes the P0571 Fault code?
It is possible to shorten the circuits in the cruise control or other buttons by spilling liquid onto the steering wheel.
These are the most common reasons that P0571 is triggered
- – Defective brake switch / cruise control
- – Badly adjusted, disengaged, or defective brake switch
- – Corroded, damaged, burned, shorted or disconnected wiring and/or connectors
- – Blown fuse
- – PCM-related issues (rarely).
What are the Symptoms of the P0571 Trouble Code
These symptoms may be present in vehicles with code P0571.
- – Make sure the engine light is on (some models may require illumination for more than one fault cycle).
- – Deactivation by PCM of cruise control system
- Brake lights not turning on when you press the brake pedal
- – Inconsistencies with the operation of cruise control
- – The cruise control control button does not function properly for some features
How do I fix the P0571 fault code?
P0571 can be caused by an electrical problem. It’s important to pay attention to the small details like the switches and fuses on the dashboard that control cruise control. Even if the brake switch is working, a problem with any of these components could cause code P0571.
These are some of the possible repairs that could resolve the P0571 fault codes:
- How to replace a broken brake switch
- – Replacing a blown fuse
- Clean the brake switch assembly of dirt and other debris
- – Repair of damaged wiring and rusty or loose connectors.
- – Reprogramming the PCM or replacing it
How Serious Is the P0571 Fault Code
The code P0571 isn’t necessarily serious. However, it can appear along with other codes if the brake pedal is having problems or the cruise control is malfunctioning. Worst case scenario: The cruise control will be disabled until the code has been decoded.
