Brake Switch "A" Circuit (P0571)
DESCRIPTION
Detection condition 1:
When the brake pedal is depressed, the stop light switch assembly outputs
a signal to the ECM. When the ECM receives the signal, it cancels control
of vehicle speed by the dynamic radar cruise control system. The fail-safe
function operates to ...
