UTILITY

NOTICE:

When replacing a millimeter wave radar sensor assembly, replace it with a new one.

If the millimeter wave radar sensor assembly has been replaced or removed/installed, be sure to perform Front Beam Axis Adjustment. If not performed, DTC C1A14 will be stored when the system is turned on.

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

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