(1) The mazda radar cruise control (MRCC) warning light (amber) flashes only when the MRCC ON switch is ON.
(2) C: CMDTC self test, D: ODDTC self test
(3) If both the front and rear wheels are rotated using a 2-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 turns the mazda radar cruise control (MRCC) warning light (amber) on, and stores DTC C1A67:92. The mazda radar cruise control (MRCC) warning light (amber) can be turned off by switching the ignition OFF (LOCK) after removing the vehicle from the 2-wheel chassis dynamometer. The stored DTC C1A67:92 can be cleared using the M-MDS.
(4) ATX
(5) If either the front or rear wheels are rotated using a 2-wheel chassis dynamometer, the DSC HU/CM determines that the DSC HU/CM is malfunctioning. As a result, the radar unit also determines that it is malfunctioning, then turns on the mazda radar cruise control (MRCC) warning light (amber) and stores DTC U0316:09. The mazda radar cruise control (MRCC) warning light (amber) can be turned off by switching the ignition OFF (LOCK) after removing the vehicle from the 2-wheel chassis dynamometer, switching the ignition ON (engine run) again, and driving the vehicle at 10 km/h or more. DTC U0316:09 can be cleared from the memory using the M-MDS.
(6) Enabled depending on malfunction content.
