NOTICE:

When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle. As a result, a DTC may be stored.
If the millimeter wave radar sensor assembly has been replaced, be sure to perform millimeter wave radar sensor assembly adjustment.

Control Mode

HINT:

This mode is used to check the operation of the pre-collision system when reproducing situations when the pre-collision system operated unnecessarily.

Operating the pre-collision brake assist control or pre-collision braking control when reproducing problem symptoms may lead to a dangerous situation. To avoid this, do not attempt to operate the pre-collision braking control, only operate the pre-collision warning control (buzzer and warning message) when reproducing the problem symptoms.

PCS Control Operated	Buzzer Sound
Pre-collision warning control	Intermittent (Long)
Pre-collision brake assist control	Intermittent (Short)
Pre-collision braking control	Continuous
