Lexus ES: Brake Switch "A" Circuit Open (P057113)
DESCRIPTION
When the brakes are applied by the dynamic radar cruise control system, the skid control ECU (brake booster with master cylinder assembly) operates the stop light switch assembly (stop light control relay) to illuminate the stop lights.
If the hybrid vehicle control ECU receives a signal from the skid control ECU (brake booster with master cylinder assembly) indicating a malfunction of the stop light control relay, DTC P057113 is stored.
