Protection Function
AWD system activates its protection function (shuts down AWD system temporarily) if AWD system detects high load continuously or the front wheel tire size differs from the rear tire size. (AWD system is automatically restored if AWD system no longer detects any overload or the tire size difference is eliminated.)
DTC | AWD warning (on information display) | Error area and root cause | Contents of protection function |
— | Refer to DLN-16, "INFORMATION DISPLAY (COMBINATION METER) : AWD Warning". | Rear final drive assembly in protection mode. It is not malfunction.
