Precautions For Diagnosis

PRECAUTIONS FOR DIAGNOSIS
^ After troubleshooting, and removing/installing of the electronic control AWD system components, check the diagnosis code using M.U.T.-III. If a diagnosis code is set, erase it and check again that no diagnosis code is set.
^ Before performing a troubleshooting, check that all four wheels and tires are same in size. The electronic control AWD system will function correctly only when all four wheels and tires are same in size.
^ If any abnormality occurs in the electronic control AWD system, it flashes the indicators (AWD and AWD LOCK) in the combination meter alternately to inform of the abnormality.
^ When the vehicle is used under some severe operational conditions (such as a long-time driving in AWD on a sandy road, slushy road or road with deep snows or towing or long hill-climbing), the electronic control AWD system illuminates the drive system fluid temperature warning lamp in the combination meter in order to protect the electronic control coupling fluid temperature, at the same time it flashes the indicator (AWD or LOCK) corresponding to the selected drive mode to inform of the abnormality.
^ The electronic control AWD system is equipped with the fail-safe function which prohibits AWD control and shifts to FWD control if any abnormality occurs in the system. If there is a risk that the vehicle behavior suddenly changes, the gradual shifting to FWD control is chosen.
