The forward recognition camera receives signals from the No. 2 skid control ECU (brake actuator assembly) corresponding to the brake control status via the CAN communication line.
When a brake control system malfunction signal is received from the No. 2 skid control ECU (brake actuator assembly), the forward recognition camera outputs U041881.

When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
When the forward recognition camera is replaced with a new one, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history (RoB) for each system.
Forward recognition camera adjustment can be performed by using either "One Time Recognition" or "Sequential Recognition".

Check the DTCs.
for HV Model:
for Gasoline Model:
Electronically controlled brake system DTCs are not output.
If U041881 is output in the pre-collision system, electronically controlled brake system DTCs may also have been output. Check the electronically controlled brake system first.
