DTC P0571/52 Stop light switch circuit malfunction
CIRCUIT DESCRIPTION
When the brake pedal is depressed, the stop light switch assy sends a signal to the ECM. When the ECM
receives this signal, it cancels the cruise control.
Fail±safe function operates to enable normal driving even if there is a malfunction in the stop light signal
circuit.
The cancel condition occurs when positive battery voltage is applied to terminal STP.
When the brake is applied, battery positive voltage is normally applied to terminal STP of the ECM through
the STOP fuse and the stop light switch assy, and the ECM turns the cruise control off.

Rear power window switch circuit
CIRCUIT DESCRIPTION
The rear power window switch controls the UP/DOWN function of the rear power window motor.
The driver door ECU (power window master switch) operates the remote control of each window UP/DOWN
function via BEAN.
