Service Notice or PrecautionEDS003AI
lCheck for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
lOverhaul should be done in a clean work area, it is preferable to work in dust proof area.
lBefore disassembly completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
lGaskets, seals and O-rings should be replaced any time when the unit is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or shop rags to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential gear oil, petroleum
jelly, or multi-purpose grease as specified for each vehicle, if necessary.

When reading wiring diagrams, refer to the following:
lGI-15, "How to Read Wiring Diagrams".
lPG-4, "POWER SUPPLY ROUTING CIRCUIT".
When performing trouble diagnosis, refer to the following:
lGI-11, "How to Follow Trouble Diagnoses".
lGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident".

4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “DIFF LOCK”.
If “DIFF LOCK” is not indicated, go toGI-50, "
CONSULT-II Data
Link Connector (DLC) Circuit".
6. Perform each diagnostic test mode according to each service
procedure.
SELF-DIAG RESULTS MODE
Operation Procedure
1. Perform “CONSULT-II SETTING PROCEDURE”. Refer toRFD-50, "CONSULT-II SETTING PROCE-
DURE".
2. With engine at idle, touch “SELF-DIAG RESULTS”.
Display shows malfunction experienced since the last erasing
operation.
NOTE:
lThe details for “TIME” are as follow:
–“0”: Error currently detected with differential lock control
unit.
–Except for “0”: Error detected in the past and memorized
with differential lock control unit.
Detects frequency of driving after DTC occurs (frequency
of turning ignition switch “ON/OFF”).
