TROUBLE DIAGNOSIS
NOTE:
1. Light tight-corner braking symptom may occur depending on driving conditions in AUTO mode. This is not
malfunction.
2. Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: LOCK
mode, steering wheel is turned fully to either sides, and accelerator pedal was depressed.
3. When the difference of revolution speed between the front and the rear wheels is large, the 4WD mode
does not change to other mode.this is not a malfunction.

4WD solenoid valve
Under the vehicle stopped with engine ON, touch UP, DOWN on
screen. Adjust 4WD solenoid command current.
Check the monitor current at that time. If monitor current is within
approx.±10%, light switch is normal.
CAUTION:
Do not continuously energize solenoid for long period of time.
ECU PART NUMBER
Ignore the ECU part number displayed in the ECU PART NUMBER MODE.
Refer to parts catalog to order the ECU.

3.INSPECTION USING 4WD MODE CHANGE-OVER SWITCH
lOn data monitor screen of the CONSULT-II, check 4WD mode switch.
lCheck if the display changes from ## to 2WD mode when the 2WD switch is pressed.
lCheck if the display changes from ## to AUTO mode when the AUTO switch is pressed.
lCheck if the display changes from ## to LOCK mode when the LOCK switch is pressed.
OK or NG
OK >> No malfunction detected.
NG >>
lNot in AUTO mode. (in 2WD or LOCK mode)
Countermeasure: Slightly depress the accelerator pedal and check that the operation mode
changes to LOCK mode.
lCheck circuit between 4WD mode switch harness connector M39 terminal No.1 (BR) and
4WD control unit harness connector E122 terminal No. 27 (BR).
(AUTO mode is not available because a malfunction is present in the 2WD mode harness.)
NOTICE:
Mechanism of 4WD mode change-over
l2WD mode: Operation changes to 2WD mode when 4WD control unit harness connector E122
terminal No. 27 (BR) is shorted to ground.
lAUTO mode: Operation changes to AUTO mode when 4WD control unit harness connector
E122 terminals No. 27 (BR) and No. 26 (L) is shorted to ground.
lLOCK mode: Operation changes to LOCK mode when 4WD control unit harness connector
E122 terminal No. 26 (L) is shorted to ground.
4WD MODES CANNOT BE SWITCHED AFTER ENGINE IS STARTED
1.INSPECTION USING 4WD MODE CHANGE-OVER SWITCH
lDrive modes cannot be switched after the engine is started.
lOn data monitor screen of the CONSULT-II, check 4WD mode switch.
lCheck if the display changes from ## to 2WD mode when the 2WD switch is pressed.
lCheck if the display changes from ## to AUTO mode when the AUTO switch is pressed.
lCheck if the display changes from ## to LOCK mode when the LOCK switch is pressed.
OK or NG
OK >> No malfunction detected.
NG >>
lCONSULT-II display does not change from ## when the 2WD switch is pressed. Check harness
of the 2WD switch.
lCONSULT-II display does not change from ## when the AUTO switch is pressed. Check har-
ness of the 2WD switch and LOCK switch.
lCONSULT-II display does not change from ## when the LOCK switch is pressed. Check har-
ness of the LOCK switch.
lPerform 4WD mode change-over switch inspection.
WHILE DRIVING, 4WD WARNING LAMP FLASHES RAPIDLY. (WHEN IT FLASHERS FOR
APPROX. ONE MINUTE, THEN DOES NOT ILLUMINATE.)
lWhile driving, 4WD warning lamp flashes rapidly. (when it flashes for approx. one minute, then does not
illuminate.)
Rapid flashing: 2 times/second
This phenomenon protects drivetrain parts when a heavy load is applied to the electronically controlled
coupling and multiple disc clutch temperature increases. It is not a malfunction.
When the difference of diameters by or with the front and rear wheel with AUTO mode the shift switch
occasionally changes to LOCK mode automatically. This is not a malfunction.
When the difference of revolution speed between the front and rear wheel with AUTO mode, the shift
switch occasionally changes to LOCK mode automatically. This is not a malfunction.
