(1) C: CMDTC self test, D: ODDTC self test
(2) The master warning light is illuminated only when the SBS/DRSS is ON.
(3) 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 and stores DTC C1A67:54. The master warning light can be turned off by switching the ignition off after removing the vehicle from the 4-wheel chassis dynamometer. The stored DTC C1A67:54 can be cleared using the M-MDS.
(4) 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 illuminates the master warning light, and stores DTC U0316:09. After the vehicle is removed from the 2-wheel dynamometer, the ignition switched off, and then switched back ON (engine ON), the master warning light turns 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.
