CAN COMMUNICATION SYSTEM
Checking procedure
1.INSPECTION START
Check the self-diagnosis results with CONSULT-II.
Status of "CAN communications" is OK?
YES >> After printing out self-diagnosis results, go to 2.
NO >> Checking is completed.
2.SYMPTOM CHECK
Check "CAN diagnosis support monitor" on data monitor.
>> After printing out monitor items, GO TOLAN-11, "
CAN SYSTEM (FOR M/T MODELS)""CAN sys-
tem". (Refer to CAN communication connection unit.)
4WD MODE SWITCH SYSTEM
1.INPUT SIGNAL CHECK
Check using the data monitor function of the CONSULT-II. While monitoring the 4WD mode switch items,
press 2WD mode switch. Check the display changes from ## to 2WD. Check the display for AUTO and LOCK
just the same. (## indicates when mode SW is not pressed.)
OK or NG
OK >>l4WD control unit input/output signal inspection
lRecheck 4WD control unit connector terminals and connection.
NG >> GO TO 3.
2.INSPECTION OF 4WD MODE SWITCH POWER SUPPLY
lDisconnect 4WD mode switch connector.
lTurn ignition switch ON.
lMeasure voltage between 4WD mode change and over switch harness connector M39 terminal No.26 (L),
No.27 (BR).
OK or NG
OK >> GO TO 4.
NG >> Harness malfunction or connector malfunction between ignition switch and 4WD mode switch
connector or connector malfunction.
Normal operation Malfunctioning
CAN COMM: OK CAN COMM: OK
CAN CIRC1: OK CAN CIRC1: UNKWN
CAN CIRC2: OK CAN CIRC2: OK
CAN CIRC3: OK CAN CIRC3: OK
26(L), 27(BR) - Body ground : 4V or more.

3.CHECK COMBINATION METER POWER CIRCUIT
1. Disconnect combination meter connector.
2. With ignition ON, check the voltage between the combination meter harness connector M44 terminal
No.46 (W/L) (LHD models) or No.59 (W/L) (RHD models) and body ground.
OK or NG
OK >> GO TO 4.
NG >> Check combination meter circuits.
4.CHECK 4WD AUTO LAMP (ON COMBINATION METER) CIRCUIT
Check continuity between combination meter terminal 46 (LHD models) or 59 (RHD models) and terminal 18.
OK or NG
OK >> Using CONSULT-II perform self-diagnosis.
NG >> Check for burned-out bulb in 4WD AUTO lamp.
4WD WARNING LAMP DOES NOT ILLUMINATE WITH IGNITION ON
1.INSPECTION OF BLOWN FUSE BETWEEN IGNITION SWITCH AND COMBINATION METER
Check blown fuse between ignition switch and combination meter.
OK or NG
OK >> GO TO 2 (No blown fuse)
NG >> Replace the fuse and perform the inspection again.
2.COMBINATION METER POWER SUPPLY CIRCUIT INSPECTION
1. Disconnect combination meter connector.
2. Check voltage between the combination meter harness connector M46 terminal No. LHD models: 46 (W/
L) RHD models: 59 (W/L) and body ground.
OK or NG
OK >> Malfunctioning combination meter.
NG >> Check fuse 10A [#11] to combination meter harness and connector.
4WD WARNING LAMP DOES NOT GO OUT SEVERAL SECONDS AFTER ENGINE
STARTED.(4WD MODE INDICATOR LAMP GOES OUT)
1.PERFORM SELF-DIAGNOSIS
Using CONSULT-II perform self-diagnosis.
OK or NG
OK >> No malfunction detected. Perform inspection again.
NG >>
lDetermine the location of the malfunction according to the result of Self-diagnosis using CON-
SULT-II. (Malfunction is present in the 4WD system.)
lCONSULT-II does not display 4WD system-related trouble codes. GO TO 2. LHD models:46 (W/L), RHD models: 59(W/L) 1(W)
- Body ground
: Battery voltage
46 (LHD models) or 59 (RHD models) - 18
: Continuity should exist.

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.
