Indication During Transition of Transfer Lever
When the 4WD AUTO SW is selected or the transfer lever
is shifted, and the signals from the AXLE switch do not
comply with the signal conditions of the 4H and 4L switch,
the transfer lever position signals generated by the 4H
and 4L switch and the N position signals are repeatedly
output at an interval of 0.8 second.

NOTE: After the 4WD AUTO SW and the transfer lever
is set to the specified position and the AXLE switch
generates compliant signals, the normal output status is
returned.
