Notes With Regard to Diagnosis

PRECAUTIONS FOR DIAGNOSIS

- After troubleshooting, and removing/installing of the electronic control AWD system components, check the diagnostic trouble code using scan tool. If a diagnostic trouble code is set, erase it and check again that no diagnostic trouble code is set.

- Before performing a troubleshooting, check that all four wheels and tires are same in size, in type, and in brand. The electronic control AWD system will function correctly only when all four wheels and tires are same in size, and tire pressure is specified value.

- If any abnormality occurs in the electronic control AWD system, it flashes the indicators (4WD and 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 display in the combination meter in order to protect the electronic control coupling fluid, at the same time it flashes the indicator (4WD 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.
