*4 :If both the front and rear wheels are rotated using a 2 or 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 unit. As a result, the radar unit detects DTC C1A67:92, and at the same time it displays a warning indication in the multi-information display. The warning indication displayed in the multi-information display disappears when the ignition is switched OFF after the vehicle is removed from the 2 or 4-wheel chassis dynamometer. The stored DTC C1A67:92 can be cleared from the memory 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, the radar unit also determines a malfunction and detects DTC U0316:09, and at the same time it displays a warning indication in the multi-information display. The warning indication displayed in the multi-information display disappears when the vehicle is driven at 10 km/h or more after the vehicle is removed from the 2-wheel chassis dynamometer, ignition is switched OFF and then switched back ON (engine on). The stored DTC U0316:09 can be cleared from the memory using the M-MDS.
