PRE-CRASH SAFETY SYSTEM UTILITY

Note

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.


  1. Control Mode

    Tech Tips


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

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

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