BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HEV Model) C13807E Stop Lamp Relay Actuator Stuck On

DESCRIPTION

When any of the following conditions are met, the skid control ECU (brake actuator assembly) sets the drive output (STPO) ON which operates the stop light control relay (stop light switch assembly) and turns on the stop lights.

Illumination Conditions:

Pre-collision brake is operating.

The dynamic radar cruise control system is operating and is applying the brakes.

Secondary collision brake is operating.

Brake hold is operating.

The parking brake is engaged while the vehicle is being driven.
