PRE-CRASH SAFETY SYSTEM UTILITY

Note


  • When replacing a millimeter wave radar sensor assembly, replace it with a new one. When the millimeter wave radar sensor assembly is replaced with a new one, it stores the country specification information received from the driving support ECU assembly.

    If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.

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

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