TROUBLESHOOTING
Check that center differential lock mode is set.
When switching differential Free - Lock, the indicator lamp will blink if the gears of the differential lock sleeve are not meshed. If this occurs, when the
tires are rotated to apply differential power to the differential, the differential locks and the indicator lamp light up.
