Front Radar Installation Angle Checking/Adjustment Overview
The front radar detects control subject in front, and recognize distance from the subject, comparing speed and etc. For these reasons the direction of installation has to be on collinear with vehicle. Therefore, installing angle inspection and adjustment have to be done in case of the front radar removed and reinstalled caused by accident or install a new front radar. Accuracy of the front radar cannot be guaranteed if inspection and adjustment have not been done in case of mentioned situation before. Front radar inspection/adjustment have to be done with either stop mode (C1) or drive mode (C2) using by diagnostic tool Perform adjustment procedure with exclusive adjustment reflector (SST) for stop mode (C1).
Information
- after operating stop mode, the accuracy will be increased if the vehicle has driven more than 10 min. (drive on straight lane which has metallic reflector.)
- Operate adjustment on real road driving (drive on the road that has many metallic fixed reflector such as guard rail) for drive mode. (C2)
Information
The cases that front radar installation angle checking/adjustment are needed.
- Front radar has been replaced
- Front radar has been removed and reinstalled.
- Line up failed DTC has been occurred
- Failure on front radar detecting and cognition function
- failed to detect vehicle in front while functioning
- often detecting error of side lane
- often detecting error even though any object is not in front
