What is P0572 fault code? What is the description of Cruise Control/Brake Switch “A” Circuit Low malfunction? How can I fix P0572 fault code What are the symptoms and causes for the P0572 fault code
What is the P0572 fault code? What does it all mean?
A code P0572 is an indication of a problem in the cruise controller system or brake switch. Also known as brake sensor or brake switch, the onboard computer is sensing a lower voltage that normal.
The brake switch is used to operate the transmission’s gear lever in vehicles that have an automatic transmission. It also turns on the brake lights when you press the pedal. You can also start vehicles with start-stop technology by pressing the brake. Operation of the cruise controller system depends on proper operation of brake switches. The brake pedal can be depressed to turn off or disable cruise control. This is especially important if you are using the cruise control system for daily trips.
The powertrain control module (PCM), if it detects low voltage signals from the brake switch “A”, it will disable cruise control. Usually, the code is P0572. The check engine lamp may still be lit.

The code’s description of the “A” circuit refers specifically to a wire, connector or harness. It refers to. To determine what it means, you will need to refer to the vehicle’s manual.
The P0572 fault code can affect vehicles of all makes and models, including but not limited to Dodge, Suzuki Chrysler, Ferrari Jeep, Ram, Lexus, Chevrolet, Lexus, Lexus, Chevrolet, and Volkswagen.
What causes the P0572 Fault code?
These are the most common reasons that P0572 is triggered
- – Cruise control adjustment knobs that have been contaminated with liquids can cause short-circuit issues.
- Defective cruise control switch
- – Bad brake light switch
- – A disengaged or incorrectly adjusted brake lever (common if modified or replaced)
- – Broken or damaged wires in the circuit for the brake switch or cruise control “A”, causing a short contact.
- – Dirt, mud, etc. Brake switch stuck because of debris
- – Use loose or rusty connectors
- – Blown fuse causing an open circuit
- PCM-related issues
What are the symptoms of P0572 Malfunction Code?
You may experience the following symptoms if your vehicle has the code P0572:
- – Check that the engine light is on.
- Cruise control not working (this is most common symptom).
- – The cruise control is turned on, but it does not engage
- – The cruise control adjustment buttons are not functioning properly
- Bad brake switch causing rear brake lights not to activate
How do I fix the P0572 fault code?
The following repairs may be able to resolve the P0572 fault code:
- Repairing a defective brake switch
- – Replacing a broken cruise control switch
- – Re-adjustment if the brake switch is not set correctly
- Clean the brake switch assembly of dirt and other debris
- – Replacing a blown fuse
- – Removing damaged wiring harness, connectors etc. Replace or repair
- – Repairing a damaged cruise control module (rarely).
- – Reprogramming the PCM or replacing it
You should check the setting and condition (resistance/voltage) of your brake switch. The brake switch test should pass. If it passes, the cruise controls knobs must be checked for fluid leakage and the switch should be tested. Before starting repairs, it is important to check for blownfuses.
Sometimes, the cruise control module is the root cause of the problem. If this is the case, the cruise control module must be tested and if necessary replaced while the vehicle runs.
It is common to mistakenly assume that the brake light switch is the problem and then replace it without checking everything. The brake light switch is the most common problem, but a blown fuse or liquid on the buttons of the cruise control can also be the cause. It is important to diagnose all possible causes.
How serious is the P0572 Fault code?
Depending on the fault, the severity of P0572 may vary. The only sign that the problem is with the cruise control switch will be the cruise system not working. This is a much more serious problem if the brake light switch is faulty. The brake switch is responsible for activating the brake lights when the brake pedal is pressed. This will allow vehicles in front to detect that you have applied the brakes. Safety of the driver is at stake if you don’t operate your brakes properly.
