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 [11/2021 - 03/2022]: Description
Forward recognition camera is connected to the front side radar sensor (RH)*1, blind spot monitor sensor RH, and headlight ECU sub-assembly LH*2 by CAN communication line.
If communication with the blind spot monitor sensor RH stops, the forward recognition camera stores DTC U0232-87.
If communication with the front side radar sensor (RH) stops, the forward recognition camera stores DTC U1236-87.*1
HINT:
When DTCs or vehicle control history (RoB) related to the front radar system is output, the forward recognition camera may output DTC U1236-87.
If communication with the headlight ECU sub-assembly LH stops, the forward recognition camera stores DTC U0241-87.*2
