(1) C: CMDTC self test
(2) The MRCC warning light (amber) flashes only when the MRCC ON switch is ON.

*3: 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 stores DTC C1A67:54 and turns the MRCC warning light (amber) on at the same time. The MRCC warning light (amber) can be turned off by switching the ignition off after removing the vehicle from the 2 or 4-wheel chassis dynamometer. The stored DTC C1A67:54 can be cleared from the memory 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 will also determine that the radar unit is malfunctioning, turn on the MRCC warning light (amber) and store DTC U0316:09 at the same time. The MRCC warning light (amber) can be turned off by switching the ignition off, and switching it back ON (engine on), and then driving the vehicle at 10 km/h {6.2 mph} or more after removing the vehicle from the 2-wheel chassis dynamometer. The stored DTC U0316:09 can be cleared from the memory using the M-MDS.
