Diagnosis Function: Notes
When the system fails
"4WD SYSTEM SERVICE REQUIRED" should be displayed at the center on the multi-information display, and "4WD" should flash at the left upper.
When the S-AWC system oil is too hot
Either of "AWC ECO", "NORMAL", "SNOW", "GRAVEL" should flash at the left upper, and "4WD SYSTEM OVERHEATING SLOW DOWN" should be displayed at the center. Then the S-AWC drive mode-selector will be disabled to avoid damage to the drive train components.
Fail-safe function
If the AWC-ECU receives an abnormal signal from sensors, switches, or solenoids, it will enter a fail-safe mode to ensure the safety of the driver and prevent damage to the system.
