(1) C: CMDTC self test, D: ODDTC 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 chassis dynamometer, the vehicle control module (V/C-module) will detect an error in the position information of the target object which is picked up by the radar sensor. As a result, the vehicle control module (V/C-module) displays a message in the center display and stores DTC C1A67:54. The message display can be turned off by switching the ignition off after removing the vehicle from the chassis dynamometer. The stored DTC C1A67:54 can be cleared using the M-MDS.
(4) If the front or rear wheels are rotated using a chassis dynamometer, the DSC HU/CM will determine that the DSC is malfunctioning. As a result, it will also be determined that the vehicle control module (V/C-module) is malfunctioning, the MRCC warning light (amber) is illuminated, and DTC U0316:09 is stored. The MRCC warning light (amber) can be turned off by switching the ignition off, and then switching it back ON (engine on), driving the vehicle at 10 km/h {6.2 mph} or more after removing the vehicle from the chassis dynamometer. DTC U0316:09 can be cleared from the memory using the M-MDS.
