*2 :If both the front and rear wheels are rotated using a 4-wheel chassis dynamometer, the radar unit determines that there is an error in the location information of the object which it detected. As a result, the radar unit stores DTC C1A67:92. The stored DTC C1A67:92 can be cleared using the M-MDS.

*3 :If either the front or rear wheels are rotated using a 2-wheel chassis dynamometer, the DSC HU/CM determines that the DSC is malfunctioning. As a result, the radar unit also determines that it is malfunctioning, stores DTC U0316:09. DTC U0316:09 can be cleared from the memory using the M-MDS.

*4 :Enabled depending on malfunction content.

*5 :If multiple warnings are displayed, they are displayed in order of importance and it is necessary to change the screen.
