(1) Without multi-information display

(2) With multi-information display

(3) C: CMDTC self test, D: ODDTC self test

(4) 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.

(5) ATX

(6) 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, turns the smart brake support/smart city brake support (SBS/SCBS) warning light (amber) on, and stores DTC U0316:09. The smart brake support/smart city brake support (SBS/SCBS) warning light (amber) turns off when the vehicle is driven at10 km/h {6.2 mph} or moreafter the vehicle is unloaded from the 2-wheel chassis dynamometer, ignition is switched off and then switched back ON (engine on). DTC U0316:09 can be cleared from the memory using the M-MDS.

(7) The light may not turn on depending on the malfunction conditions.

(8) Enabled depending on malfunction content.
