Toyota Yaris: Dynamic Radar Cruise Control System / Brake Switch "A" Circuit Open (P057113)

Toyota Yaris XP210 (2020-2025) Reapir and Service Manual / Engine & Hybrid System / Cruise Control / Dynamic Radar Cruise Control System / Brake Switch "A" Circuit Open (P057113)

DESCRIPTION

When the brakes are applied by the dynamic radar cruise control system, the skid control ECU (brake actuator assembly) operates the stop light switch assembly (stop light control relay) to illuminate the stop lights.

If the ECM receives a signal from the skid control ECU (brake actuator assembly) indicating a malfunction of the stop light control relay, DTC P057113 is stored.
