TROUBLE DIAGNOSIS FOR SYMPTOMS

DIAGNOSTIC PROCEDURE
1. CHECK PARKING BRAKE SWITCH SIGNAL
With CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
3. Operate parking brake and read out monitor “P BRAKE SW”.
OK or NG
OK >> GO TO 2.
NG >> Check the following. If any items are damaged, repair or
replace damaged parts.

Parking brake switch

Brake warning lamp circuit. Refer to DI-36, "Wiring
Diagram — WARN —/LHD Models" or DI-44, "Wiring Diagram — WARN —/RHD Models" .
2. CHECK 4WD SOLENOID
Check 4WD solenoid. Refer to TF-39, "
COMPONENT INSPECTION" .
OK or NG
OK >> GO TO 3.
NG >> Replace electric controlled coupling for malfunction of 4WD solenoid. Refer to RFD-22, "
Disas-
sembly and Assembly" .
3. CHECK 4WD CONTROL UNIT
Check 4WD control unit input/output signal. Refer to TF-30, "
4WD Control Unit Input/Output Signal Reference
Va l u e s" .
OK or NG
OK >> GO TO 4.
NG >> Check 4WD control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
4. SYMPTOM CHECK
Check again.
OK or NG
OK >>INSPECTION END
NG >> Replace electric controlled coupling for mechanical malfunction (mechanical engagement of
clutch is not possible.). Refer to RFD-22, "
Disassembly and Assembly" .
While Driving, 4WD Warning Lamp Flashes Rapidly (When Flashing in Approx.
1 Minute and Then Turning OFF)
EDS001VZ
NOTE:
Rapid flashing: 2 times/second
This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. It is not a malfunction.
When this symptom occurs, stop vehicle and allow it to idle for some times. Flashing will stop and system will
be restored.

DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.

Tire pressure

Wear condition

Longitudinal tire size (There shall be no difference of tire size between front and rear tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)
2. CHECK INPUT SIGNAL OF TIRE DIAMETER
With CONSULT-II
1. Start engine.
2. Drive at 20 km/h (12 MPH) or more for approx. 200 seconds.
3. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
4. Check monitor “DIS-TIRE MONI”.
Display of
“DIS-TIRE MONI”
“0-4mm”>>INSPECTION END
Except for “0-4mm”>>GO TO 3.
3. CHECK 4WD CONTROL UNIT
Check 4WD control unit input/output signal. Refer to TF-30, "
4WD Control Unit Input/Output Signal Reference
Va l u e s" .
OK or NG
OK >> GO TO 4.
NG >> Check 4WD control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
4. SYMPTOM CHECK
Check again.
OK or NG
OK >>INSPECTION END
NG >> Replace 4WD control unit.
