PRECAUTIONS FOR DIAGNOSIS

M12704100007USA0000010000

｠

After troubleshooting, and removing/installing of the
electronic control AWD system components, check
the diagnosis code using M.U.T.-III. If a diagnosis
code is set, erase it and check again that no
diagnosis code is set.

｠

Before performing a troubleshooting, check that all
four  wheels  and  tyres  are  same  in  size.  The
electronic  control  AWD  system  will  function
correctly  only  when  all  four  wheels  and  tyres  are
same in size.

｠

If any abnormality occurs in the electronic control
AWD system, it flashes the indicators (AWD and
AWD LOCK) in the combination meter alternately to
inform of the abnormality.

｠

When the vehicle is used under some severe
operational conditions (such as a long-time driving

in AWD on a sandy road, slushy road or road with
deep  snows  or  towing  or  long  hill-climbing),  the
electronic control AWD system illuminates the drive
system  fluid  temperature  warning  lamp  in  the
combination meter in order to protect the electronic
control coupling fluid temperature, at the same time
it  flashes  the  indicator  (AWD  or  LOCK)
corresponding to the selected drive mode to inform
of the abnormality.

｠

The electronic control AWD system is equipped with
the fail-safe function which prohibits AWD control
and shifts to FWD control if any abnormality occurs
in the system. If there is a risk that the vehicle
behaviour suddenly changes, the gradual shifting to
FWD control is chosen.

Drive mode indicator

Vehicles for USA

Vehicles for Canada

Check that the AWD/LOCK indicators illuminate as follows:

Switch the drive mode selector to the LOCK mode.

When the ignition switch is turned ON, the AWD/LOCK
indicators illuminate.

After the engine starts, the AWD/LOCK indicators go off.

Otherwise, check the diagnosis code.

On troubleshooting, if the ignition switch is turned
ON while disconnecting connector(s), diagnosis
code(s) associated with other system may be set.

On completion, confirm all systems for diagnosis
code(s). If diagnosis code(s) are set, erase them
all.

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC C1078: Tire with incorrect diameter equipped

M12704100012USA0000010000

If there is any problem in the CAN bus lines, an incorrect
DTC may be set. Prior to this diagnosis, always diagnose
the CAN bus lines.

OPERATION
If the vehicle is driven with a tire with incorrect
diameter (high-pressure type spare tire or flat tire)
installed to either wheel in the AWD mode, AWD-ECU
controls the coupling in high torque. If this is the case,
the coupling temperature may rise to cause a seizure.

DTC SET CONDITIONS
If  the  following  conditions  are  met,  AWD-ECU
gradually  reduces  the  AWD  control  torque  to  the
specified  torque,  flashes  the  AWD/LOCK  indicators
alternately, and sets the DTC No. C1078.

｠

AWD selector switch: AWD/LOCK

｠

If the vehicle is driven with abnormal tire pressure
or tires of different brands, DTC No. C1078 is set
and the mode is switched to the AWD AUTO mode.

｠

If the difference in rotation speed between the front
and rear wheels exceeds a specific value
continuously, the DTC No. C1078 is set, the AWD/
LOCK indicators flash alternately, and the mode is
switched to the 2WD mode.
