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 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 switch assembly, DTC P057113 is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from |
|---|---|---|---|---|
| P057113 | Brake Switch "A" Circuit Open | When the dynamic radar cruise control system is operating, the ECM detects a signal indicating a stop light switch assembly malfunction from the skid control ECU (brake actuator assembly) for approximately 1 second or more. | Electronically controlled brake system | Cruise Control |
Check the electronically controlled brake system.
When P057113 is detected by the dynamic radar cruise control system, C1380 may also be detected in the electronically controlled brake system. Therefore, check the electronically controlled brake system first when P057113 is detected.
