Step 11
NOTE:
D
Confirm the operation conditions when changing high
and low range.
– The car stops. (less than 2 km/h or 1.2 mph and
engine speed less than 1500 rpm)
– The AT selector position is neutral.
– The brake is applied (brake switch: ON)
D
Verify the completion of changing the high/low range
by the TOD indicator on the instrument panel.

1. Clear the trouble code.
2. Confirm the condition and operation of the transfer range
changing and check the state of the TOD indicator. Change
the transfer to the low from the high and vice versa.
Is the transfer changed to the low from the high and to the high
from the low?
The transfer is
changed in both
ranges by the
correct operation.
Operate the
transfer
according to

This code does not indicate the trouble of the transfer
or ECU, and is memoried when an error operation is
carried out under high-low motor running.
Therefore this code is not memoried if the transfer is
operated according to
“Owner’s Manual”.
