Po571 & po504

P0571 = Cruise Control/Brake Switch A Circuit Malfunction
P0504 = Brake Switch "A"/"B" Correlation

I'd say that Brake Switch Circuit A is your problem. Check the wiring connection on the switch (located on the brake pedal near the firewall), then if that seems good, replace the switch.

I have code number p0571 i cant figure out what it is i fixed the brake light switch already but i keep getting the same code p0571

A couple of things. Is your cruise control working? If not, that's why light is on. And the other question - Did you reset computer (w/scanner) after replacing brake light switch? They don't reset themselves.
