ADVANCED DRIVER ASSISTANCE SYSTEM FRONT CAMERA SYSTEM(Production Date from 2023/04) Steering Pad Switch Circuit
DESCRIPTION
ECM*1 or hybrid vehicle control ECU*2 performs cruise control based on signals from the driving assist switch, +RES switch, -switch, CANCEL switch (steering pad switch assembly).
Forward recognition camera changes the driving support mode, turns LTA ON/OFF, and sets the vehicle-to-vehicle distance based on signals from the driving assist mode select switch, LTA switch, and vehicle-to-vehicle distance switch (steering pad switch assembly).
*1: for Gasoline Model
*2: for HEV Model

CAUTION / NOTICE / HINT
- NOTICE:
- ·
The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System.
·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 the forward recognition camera will not match the information from the vehicle and a DTC may be stored.
·When the forward recognition camera has been replaced with a new one, make sure to clear all stored vehicle control history of each system and the forward recognition camera beam axis alignment data.
- HINT:
-
Forward recognition camera beam axis alignment can be performed by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment Value Write".
