PRECAUTIONS FOR DIAGNOSIS

M1274000500088

• After troubleshooting, and removing/installing of 

the electronically controlled 4WD system compo-
nents, check the diagnosis code using M.U.T.-III. 
If a diagnosis code is set, erase it and check 
again that no diagnosis code is set.

• Before performing a troubleshooting, check that 

all four wheels and tyres are same in size, in 
type, and in brand. The electronically controlled 
4WD system will function correctly only when all 
four wheels and tyres are same in size, and tyre 
pressure is specified value.

• If any abnormality occurs in the electronically 

controlled 4WD system, "4WD-E" and "LOCK" 
indicators in the combination meter will illuminate 
or a message will be displayed to warn the driver. 

• When the vehicle is used under some severe 

operational conditions (such as a long-time driv-
ing in 4WD on a sandy road, slushy road or road 
with deep snows or towing or long uphill driving), 
the electronically controlled 4WD system will illu-
minate "4WD-E" and "LOCK" indicators or dis-
play a message to warn the driver.

• The electronically controlled 4WD system is 

equipped with the fail-safe function which prohib-
its 4WD control and shifts to 2WD control if any 
abnormality occurs in the system. If there is a risk 
that the vehicle behaviour suddenly changes, the 
gradual shifting to 2WD control is chosen.

Warning display

If a malfunction occurs in the electronically controlled 
4WD system, either of the followings operates to 
alert you to check a diagnosis code.

• The drive mode indicators flash simultaneously or 

alternately <Standard meter>.

• The drive mode display on the multi-information 

display flashes, and a message is shown on the 
warning display <High contrast meter>.

FAIL-SAFE FUNCTION

FAILURE DETECTION

4WD-ECU performs the following checks at a timing 
shown in the chart below. 4WD-ECU determines the 
malfunction occurred when the failure detection con-
ditions are met, and it sets the diagnosis code and 
executes the countermeasures for trouble. When the 
failure resume conditions are met, ECU determines 
the status is normal, and resumes the system.

Start-up (Initial check just after the ignition 

switch is turned ON.)

1. CPU check

• Performs the ROM and RAM check.

2. Actuator check

• After CPU check has been completed, check 

the driving voltage with the actuator relay 
OFF.

Always (During ignition ON status other than ini-

tial check operation)

1. CPU check

• Performs CAN communication and interactive 

check between CPUs.

2. Power supply check

• Monitors the CPU supply voltage and checks 

if the voltage is within specifications.

3. Actuator check

• Checks if the actuator relay turns ON accord-

ing to the control.

• Compares the command current value from 

CPU with the monitored current and checks if 
they agree.

4. External wire connection check

• Checks if the input and output of each exter-

nal wire connection is open, shorted, or stuck.

CAUTION

On troubleshooting, if the ignition switch is turned ON while disconnecting connector(s), diagnosis 
code(s) associated with other system may be set. On completion, confirm all systems for diagnosis 
code(s). If diagnosis code(s) are set, erase them all.
