Functions of Indicator Lamp

Before Judging That Troubles Occur (Unfaulty mode)
When Switching from 2WD to 4WD
1. In case that blinking frequency of the 4WD indicator changes from 2Hz to 4Hz.
When heavy synchronization load is needed, the motor actuator repeats the transfer gear shifting up to 3 times. The 4WD indicator lamp will blink (2Hz) while the motor actuator attempts shifting. If after the 3rd attempt the shifting fails, the 4WD indicator lamp will blink faster (4Hz) and the motor actuator will return to 2WD mode.
Heavy synchronization load occurs by
- At severe low temperatures.
- Higher rotational difference in speed between the front wheels and axles during cornering.
Solution 1: Attempt the 4WD mode again at a lower speed or when the vehicle is at a stop.
2. In case that the 4WD indicator continues blinking by 2Hz for more than 11.5 seconds.
When there is rotational difference in speed between the front wheels and axles, the front wheels and the front axles may have difficulty engaging. The blinking 4WD indicator lamp (at 2Hz) will indicate that the transfer case is shifting into the 4WD mode, however it will blink faster (4Hz) if shifting into 4WD mode is impossible, unless rotational difference and phase difference does not exist.
Solution 2: If the vehicle is moving, drive the vehicle straight while accelerating and decelerating, and if the vehicle is at a stop, move the vehicle forward and backward for 2 to 3 meters.

When Switching from 4WD to 2WD
1. When the 4WD indicator lamp continues to blink (at 2Hz) .
The 4WD indicator lamp continues to blink (at 2Hz) until both shifting the transfer gear and disconnecting the front wheels are completed when switching 4WD to 2WD. When drive line is loaded with torsional torque, the shifting transfer gear and disconnecting front wheels are impossible. In this case, removal of torsional torque on drive line make the shifting transfer gear and disconnecting front wheels possible.
Solution 3: If the vehicle is moving, drive the vehicle straight while accelerating and decelerating, and if the vehicle is at a stop, move the vehicle forward and backward for 2 to 3 meters.
2. When the 4WD indicator lamp blinking pattern changes (from 2Hz to 4Hz).
Check the position of transfer lever. Is it in the "4L" position? Shifting from 4WD to 2WD while at "4L" will not occur.
Solution 4: Push the 4WD switch ON (to 4WD), then shift the transfer lever to "High" position and push the 4WD switch Off (to engage to 2WD).
