Toyota Tacoma 2015-2018 Service Manual: Brake Switch "A" Circuit Open (P057113)
DESCRIPTION
When the brakes are applied by the dynamic radar cruise control system, the skid control ECU (master cylinder solenoid)*1 or skid control ECU (brake actuator assembly)*2 operates the stop light switch assembly (stop light relay) to illuminate the stop lights.
If the ECM receives a stop light switch control relay malfunction signal from the skid control ECU (brake actuator assembly), DTC P057113 is stored.
