The No. 2 skid control ECU (brake actuator assembly) sends a stop light operation request signal to the stop light control relay (stop light switch assembly). When the No. 2 skid control ECU (brake actuator assembly) detects a malfunction relating to the stop light circuit, the forward recognition camera is notified via CAN communication, and C142571 is output.

| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from | Priority |
|---|---|---|---|---|---|
| C142571 | Stop Light Relay Actuator Stuck | for HV Model:
Once 3 seconds elapse after turning the ignition switch to ON, the system receives a stop light circuit malfunction signal from the No. 2 skid control ECU (brake actuator assembly) for approximately 1 second or more. for Gasoline Model:
Once 3 seconds elapse after turning the ignition switch to ON, the system receives a stop light circuit malfunction signal from the skid control ECU (brake actuator assembly) for approximately 1 second or more. |
Electronically controlled brake system | Pre-Collision System | A |
Check the electronically controlled brake system.
When C142571 is detected by the pre-collision system, C13807E or C13807F may also be detected in the electronically controlled brake system. Therefore, check the electronically controlled brake system first when C142571 is detected.
