*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 is detected by the radar sensor. As a result, the radar unit illuminates the master warning light, displays "MRCC Inspection Required", "SBS Inspection Required", or "DRSS Inspection Required" on the LCD, and stores DTC C1A67:54. The master warning light and "MRCC Inspection Required", "SBS Inspection Required", or "DRSS Inspection Required" indication can be turned off by switching the ignition off (LOCK) after removing the vehicle from the 4-wheel chassis dynamometer. The stored DTC C1A67:54 can be cleared using the M-MDS.

*5 :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, it determines that the radar unit is also malfunctioning, then flashes the MRCC warning light (amber), illuminates the master warning light, and stores DTC U0316:09. After the vehicle is removed from the 2-wheel dynamometer, the ignition switched off (LOCK), and then switched back ON (engine ON), the MRCC warning light (amber) and the master warning light turn off when the vehicle is driven at 10 km/h {6.2 mph} or more. Clear DTC U0316:09 from the memory using the M-MDS.
