OUTLINE
All-mode 4WD transfer and A/T are controlled by the same control unit and sensors.
If a malfunction occurs in the all-mode 4WD system, the 4WD warning lamp lights up to indicate the system malfunction. There are two ways to identify the cause of the malfunction.
1. Performing the self-diagnosis. (The 4WD warning lamp will indicate what kind of malfunction has occurred by flickering.)
2. Performing diagnosis using CONSULT.
