PRE-COLLISION  PRE-COLLISION SYSTEM  C142571  Stop Light Relay Actuator Stuck  


DESCRIPTION

for HV Model:

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.


for Gasoline Model:

The 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 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
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

HINT:

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.
