SYMPTOM DIAGNOSIS

HEAVY TIGHT-CORNER BRAKING SYMPTOM OCCURS

Description

INFOID:0000000010755288

Heavy tight-corner braking symptom occurs when the vehicle is driven and the steering wheel is turned fully to
either side after the engine is started.
NOTE:
Light tight-corner braking symptom may occur depending on driving conditions. This is not malfunction.

Diagnosis Procedure

INFOID:0000000010755289

1.

PERFORM ECM SELF-DIAGNOSIS

With CONSULT

Perform self-diagnosis for “ENGINE”.

Is any DTC detected?

YES

>> Check the DTC. Refer to 

ECM-93, "DTC Index"

 (MR20DD).

NO

>> GO TO 2.

2.

PERFORM SELF-DIAGNOSIS

With CONSULT

Perform self-diagnosis for “ALL MODE AWD/4WD”.
Is DTC “U1000” detected?

YES

>> Proceed to 

DLN-58, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

CHECK 4WD SOLENOID

Perform the trouble diagnosis of the 4WD solenoid. Refer to 

DLN-40, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace the error-detected parts.

4.

CHECK ELECTRIC CONTROLLED COUPLING

1.

Turn the ignition switch OFF.

2.

Set the transaxle to neutral. Release the parking brake.

3.

Lift up the vehicle.

4.

Rotate the propeller shaft by hand.

5.

Hold rear wheel of right and left lightly.

Does rear wheel rotate?

YES

>> Replace electric controlled coupling for mechanical malfunction (clutch sticking etc.). Refer to

DLN-76, "Exploded View"

.

NO

>> Check each harness connector pin terminal for disconnection.

VEHICLE DOES NOT ENTER 4WD MODE

Description

INFOID:0000000010755290

Vehicle does not enter 4-wheel drive mode even though 4WD warning is not displayed.

Diagnosis Procedure

INFOID:0000000010755291

1.

CHECK INFORMATION DISPLAY (COMBINATION METER)

Perform the trouble diagnosis of combination meter. Refer to 

MWI-54, "Work flow"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace the error-detected parts.

2.

CHECK PARKING BRAKE SWITCH SIGNAL

With CONSULT

Check “PARKING BRAKE SW SIG” of CONSULT “DATA MONITOR” for “ALL MODE AWD/4WD”.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Proceed to 

PB-67, "Component Inspection"

.

3.

CRUISE TEST

Drive the vehicle for a period of time.

Does any symptom occur?

YES

>> Replace electric controlled coupling for mechanical malfunction (mechanical engagement of

clutch is not possible). Refer to 

DLN-76, "Exploded View"

.

NO

>> Check each harness connector pin terminal for disconnection.

4WD HIGH TEMP IS DISPLAYED ON INFORMATION DISPLAY

Description

INFOID:0000000010755292

While driving, 4WD warning (4WD High Temp. Stop vehicle) is displayed on information display (combination
meter).
• This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and

multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before 4WD warning (4WD High Temp. Stop vehicle) is displayed. Both cases are not malfunction. Refer to

DLN-26, "Protection Function"

.

• When this symptom occurs, stop vehicle and allow it to idle for some times. Displays will stop and system

will be restored.

TIRE SIZE INCORRECT IS DISPLAYED ON INFORMATION DISPLAY

Description

INFOID:0000000010755293

While driving, 4WD warning (Tire Size Incorrect: See Owner’s Manual) is displayed on information display
(combination meter).

Diagnosis Procedure

INFOID:0000000010755294

1.

CHECK TIRE

Check the following.
• Tire pressure
• Wear condition
• Front and rear tire size (There is no difference between front and rear tires.)
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts. And then, drive the vehicle at speed of 20 km/h (12 MPH)

or more for 5 seconds or more. Improper size information is initialized accordingly.

2.

CHECK INPUT SIGNAL OF TIRE DIAMETER

 With CONSULT

1.

Start the engine.

2.

Drive at 20 km/h (12 MPH) or more for approximately 4 minutes continually.

3.

Check “DIS-TIRE MONI” of CONSULT “DATA MONITOR” for “ALL MODE AWD/4WD”.

Does the item on “DATA MONITOR” indicate “0 - 4 mm”?

YES

>> INSPECTION END

NO

>> GO TO 3.

3.

TERMINAL INSPECTION

Check 4WD control unit harness connector for disconnection.

Is the inspection result normal?

YES

>> Replace 4WD control unit. Refer to 

DLN-72, "Removal and Installation"

.

NO

>> Repair or replace the error-detected parts.
