AWD Control Unit: Fail-Safe: System
- If any malfunction occurs in electrical system, and control unit detects the malfunction, warning lamp on combination meter turns ON to indicate system malfunction.
- When warning lamp is ON, vehicle changes to rear-wheel drive or shifts to 4-wheel drive (front-wheels still have some driving torque).
- system activates its protection function (shuts down system temporarily) if system detects high load continuously or the front wheel tire size differs from the rear tire size. (system is automatically restored if system no longer detects any overload or the tire size difference is eliminated.)
