What is a brake switch a circuit?
Your brake light switch is a simple spring-loaded switch that is held open by a tab on the brake pedal, keeping the brake lights off. When you push the pedal down, the spring causes the switch to close, completing the electrical circuit and turning on the brake lights.
What are the symptoms of a p0572 diagnostic code?
Symptoms of a P0572 diagnostic code may include: Cruise control completely inoperative. Erratic cruise control operation. Certain functions not operating as they should (e.g. set,resume, accel., etc.) Cruise control turning on but not engaging. No brake lights if the brake light switch is faulty.
When does the p0571 brake switch a circuit malfunction?
The P0571 Cruise Control/Brake Switch A Circuit Malfunction and related codes ( P0572 and P0573) are set when the ECM (engine control module) detects a malfunction within the cruise control/brake switch “A” circuit. Example of a brake switch and it’s location:
What causes a p0572 cruise control code to be low?
Causes for this P0572 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.
What causes the p0572 code to come on?
If the computer determines that the brake switch circuit voltage is low, it will disable cruise control and usually set the P0572 code. The Check Engine light may come on as well. What causes the P0572 code? There are several possible causes of the P0572 code, including the following:
The P0571 Cruise Control/Brake Switch A Circuit Malfunction and related codes ( P0572 and P0573) are set when the ECM (engine control module) detects a malfunction within the cruise control/brake switch “A” circuit. Example of a brake switch and it’s location:
What does it mean when your Cruise Control says p0572?
When Error Code P0572 is stored, that means a malfunction in the cruise control/brake switch “A” circuit has been detected, specifically indicating a low voltage condition within the circuit. Other Cruise Control/Brake Switch A Circuit Malfunction and related codes include:
