Front final gear system failure:
The differential lock indicator and 4WD indicator (4) will both flash
when there is any abnormality in the front final gear system. If this
occurs, the front final gear actuator will stop moving, and the front
final gear system will be fixed in the current position, either 2WD
mode, 4WD mode or front differential lock mode.
If both the differential lock indicator and 4WD indicator flash, reduce
speed and take your ATV to your dealer as soon as possible.
