DTC U0232-87: Lost Communication with Side Obstacle Detection Control Module "A" Missing Message; DTC U0241-87: Lost Communication with Headlamp Control Module "A" Missing Message; DTC U1236-87: Lost Communication with Cruise Control Front Distance Range Sensor Front Side "B" Missing Message [10/2022 - ]: Description
Forward recognition camera is connected to the blind spot monitor sensor, headlight ECU sub-assembly LH*1 and front side radar sensor*2 by CAN communication line.
If communication with the blind spot monitor sensor stops, the forward recognition camera stores DTC U0232-87.
If communication with the headlight ECU sub-assembly LH stops, the forward recognition camera stores DTC U0241-87.*1
If communication with the front side radar sensor stops, the forward recognition camera stores DTC U1236-87.*2
