P1572 Brake Circuit Fault - 2001 Lincoln LS Check Engine Light Issue
My 2001 Lincoln LS has triggered a P1572 diagnostic code, which indicates a brake pedal switch circuit fault. The check engine light came on, and upon inspection, both the driver's side and center brake lights are not functioning. While I initially thought a blown bulb might be causing this, I'm unsure whether a single burned-out bulb would trigger the P1572 code—especially since the system detects a circuit malfunction. Any insights, troubleshooting tips, or experiences with this specific fault on a 2001 Lincoln LS would be greatly appreciated.
The P1572 code typically points to an issue with the brake light switch. Ensure the brake light switch is properly installed and making consistent contact. A faulty or dirty switch can cause false readings, leading to the DTC.
