What is B0587?

DTC B0587 refers to a diagnostic trouble code indicating a malfunction in the brake switch circuit. This code commonly appears in vehicles like the 2015-2018 Honda Civic, 2013-2017 Ford Escape, and 2014-2016 Chevrolet Malibu. The brake switch is crucial for ensuring that the brake lights function correctly and for enabling systems like cruise control and electronic stability control. When the brake switch fails or there’s an issue in the circuit, it can prevent the brake lights from illuminating when the brake pedal is pressed, leading to safety concerns. Additionally, this malfunction can cause other systems to behave erratically, such as preventing the engine from starting or interfering with transmission shifting. Consequently, if you encounter this trouble code, it’s essential to address it promptly to maintain vehicle safety and performance. Ignoring this code could result in more significant electrical issues or even accidents, as other drivers may not be able to see when you are braking.

Symptoms

Common symptoms when B0587 is present:

  • The check engine light illuminates, indicating an issue that requires attention.
  • The brake lights may not function properly, leading to potential safety hazards when braking.
  • You may experience difficulties starting the engine, as some vehicles require the brake pedal to be pressed to start.
  • Cruise control may not engage or disengage properly, affecting your driving convenience.
  • In some cases, the vehicle may shift erratically or enter limp mode due to the brake switch malfunction.

Possible Causes

Most common causes of B0587 (ordered by frequency):

  1. The most common cause of DTC B0587 is a faulty brake switch, which accounts for about 60% of cases. This switch can wear out over time or become misaligned.
  2. Another possible cause is damaged wiring or poor connections in the brake switch circuit, which can occur from wear and tear or exposure to moisture (approximately 25% likelihood).
  3. Less frequently, issues with the vehicle's control module may lead to this code, particularly in vehicles with complex electrical systems. Preventive measures include regular inspections of the vehicle's wiring.
  4. In rare cases, a malfunctioning ABS module can trigger this code, which is more serious and requires immediate attention.
  5. Finally, some vehicles may experience this code due to software glitches in the vehicle's computer system, requiring a software update or reprogramming.
