April 5, 2026: LEMON Manuals is launched! Read the announcement.

Work Procedure

NOTE: In fail-safe mode, can not perform work support. (Except that DTC P181F is detected.)

CONFIRM REPLACING PARTS
Confirm the replacing parts.

What is the replacing parts?

Transfer control unit: GO TO 2.

Transfer control actuator: GO TO 3.

Transfer assembly: GO TO 4.

WRITE UNIT PARAMETER (1)

With CONSULT

Make the new unit parameter with the following procedure.

Confirm the letter of unit parameter (A).
NOTE:
- This illustration is a sample.
- For this illustration, the unit parameter is "G3" and the letter of unit parameter is "G".

Confirm the letter of transfer control actuator parameter (B).
NOTE:
- Original transfer control actuator does not have marking of letter.
- Just in case that transfer control actuator has been replaced, it has marking of letter.
- This illustration is sample of replaced transfer control actuator.
- For this illustration, the letter of transfer control actuator parameter is "H".

The new letter of unit parameter	C	D	E	E	F	G	G	H	J

NOTE: For the sample illustrations, the new letter of unit parameter is "F".

Add the same number of unit parameter behind the new letter of unit parameter.

NOTE: For the sample illustration, the number of unit parameter is "3" and new unit parameter is "F3".

Turn the ignition switch OFF to ON.
Select "UNIT CHARACTERISTICS WRITE" of CONSULT "WORK SUPPORT" for "ALL MODE AWD/4WD".
Input new unit parameter.
Select "Start".
Check that "UNIT CHARACTERISTICS WRITE COMPLETED" or "UNIT CHARACTERISTICS WRITE ALREADY WRITTEN" is displayed.
: WORK END.
