M.U.T.-III cannot communicate with the electronically controller 4WD system.

Shifting the 4WD switch does not change the mode

The tight corner braking phenomenon* appears with the 4WD switch in the 4WD ECO or 4WD AUTO position.
note The vehicle is tuned so that the tight corner braking phenomenon appears at a certain level with the drive mode in the LOCK position.

No diagnosis code is set even when the 4WD-E/LOCK indicator lamps flash.

note *Tight corner braking phenomenon: When a 4WD vehicle makes sharp cornering in a paved road at low speed (ex. parallel parking), there is a difference in turning radius between front and rear wheels. If such a difference can no longer be compensated by tyre slippage, the vehicle behaves as if it is under braking.
