TROUBLE DIAGNOSIS
2. Check using the active test function of the CONSULT-II.
Using active test mode of CONSULT-II, supply current to the 4WD solenoid valve and check that the mon-
itor current becomes close to this supply current.
lThe 4WDcontrol unit is normal when the difference between 4WD solenoid valve current and the monitor
current is within±10%.
It is necessary to inspect the electronically controlled coupling assembly.

1.4WD/ABS CONTROL MODULE CONNECTOR CONNECTION INSPECTION
lRemove glove box on the passenger side and check 4WD/ABS control module connector for proper con-
nection.
Is inspection result OK?
YES >> Proceed to 2. (4WD/ABS control unit connector is properly connected.)
NO >>
lConnect the 4WD/ABS control unit connector and perform inspection again.
2.USING CONSULT, PERFORM SELF-DIAGNOSIS.
lConnect the CONSULT and perform self-diagnosis.
Is inspection result OK?
YES >> GO TO 3. (No self-diagnosis malfunction indicated.)
NO >> Perform inspection according to the trouble codes displayed on the CONSULT. Refer to the “DTC
chart”. Example) Monitor value becomes Approx. 1 A for 4WD solenoid current 1 A setting.

3.CHECK CONTINUITY BETWEEN IGNITION SWITCH AND ABS WARNING LAMP.
lDisconnect 4WD/ABS control unit connector.
lCheck continuity between ignition switch and 4WD/ABS control module terminal No. 4. (Open circuit
check)
Is inspection result OK?
YES >> Continuity exists. Connect 4WD/ABS control module connector, check again.
NO >> Continuity does not exist. Check ABS warning lamp path.
4.CHECK FUSE.
lCheck if Fuse No.8 is working normally.
Is the check result OK?
YES >> Repair or replace the harness in between 4WD/ABS control unit and IGN.
NO >> Replace the fuse and replace again.
lIf the figure of the monitor is with in±10% of the set value of E-TS solenoid electric current, 4WD/ABS C/
U is operating normally.Check for electric control coupling ASSY is required.
4WD warning lamp does not illuminate with ignition ON.EFS001BR
1.INSPECTION OF BLOWN 4WD WARNING LAMP BULB
lRemove glove box on the passenger side and disconnect the 4WD/ABS control unit connector.
lConfirm continuity between 4WD/ABS control unit connector terminals No. 3 (IGN) and No. 4 (ABS warn-
ing lamp).
Is inspection result OK?
YES >> GO TO 3. (Continuity exists.)
NO >>
lCheck 4WD warning lamp harness.
lRemove meter control module assembly and check for blown 4WD warning lamp bulb.
2.4WD ACTUATOR RELAY HARNESS INSPECTION
lOpen the hood and check that the 4WD relay is properly installed in the relay box.
lConfirm continuity between 4WD/ABS control unit connector terminals No. 7 (4WD warning lamp) and No.
104 (ground).
lConfirm continuity between 4WD/ABS control unit connector terminals No. 3 (IGN) and No. 18 (4WD
actuator relay).
Is inspection result OK?
YES >> Continuity exists. Connect 4WD/ABS control unit connector, check again.
NO >> Check ABS warning lamp harness.
4WD warning lamp does not go out several seconds after engine is started.
(Drive mode indicator lamp goes out.)

1.USING CONSULT, PERFORM SELF-DIAGNOSIS.
4WD warning lamp does not go out several seconds after the engine is started. (Drive mode indicator lamp
goes out.)
Is inspection result OK?
YES >> No malfunction detected. Perform inspection again.
NO >>
lDetermine the location of the malfunction according to the result of self-diagnosis using CON-
SULT. (Malfunction is present in the 4WD system.)
lCONSULT-II does not display ABS -related trouble codes. Proceed to 2.

TROUBLE DIAGNOSIS
2.4WD/ABS CONTROL UNIT CONNECTOR CONNECTION INSPECTION
lRemove glove box on the passenger side and check 4WD/ABS control unit connector for proper connec-
tion.
Is inspection result OK?
YES >> 4WD/ABS control unit connector is properly connected.
NO >> Reconnect the 4WD/ABS control module connector properly and perform inspection again.
Heavy tight-corner braking symptom occurs when the vehicle is driven in AUTO
mode and the steering wheel is turned fully to either side after the engine is
started.

1.USING CONSULT, PERFORM SELF-DIAGNOSIS.
Heavy tight-corner braking symptom occurs when the vehicle is driven in AUTO mode and the steering wheel
is turned fully to either side after the engine is started.
Is inspection result OK?
YES >> GO TO 2. (No self-diagnosis malfunction indicated.)
NO >> Determine the location of the malfunction according to the result of self-diagnosis using CON-
SULT. (Malfunction is present in the 4WD system.)
2.CHECK USING THE DATA MONITOR FUNCTION OF THE CONSULT.
lPerform inspection by the data monitor function of the CONSULT.
lCheck that the operation is in AUTO mode.
lMeasure voltage when the accelerator pedal is not depressed. (Accelerator pedal not depressed: Approx.
0.5V or lower)
lMeasure the current supplied to the E-TS solenoid valve. (Accelerator pedal not depressed: Approx. 0A)
Is inspection result OK?
YES >> GO TO 3. (No self-diagnosis malfunction indicated.)
NO >>
lNot in AUTO mode. GO TO 3.
lVoltage when accelerator pedal is not depressed is higher than approximately 0.5V.
lE-TS solenoid valve current when accelerator pedal is not depressed is other than 0A.
lCountermeasure: Keep the vehicle idling for approximately 15 minutes before checking again.
(Voltage when accelerator pedal is not depressed will be automatically reset to zero during this
period.)

1. ECM is located behind the glove box. For this inspection,
remove glove box.
2. Remove ECM harness protector.
3. Perform all voltage measurements with the connector con-
nected. Extend tester probe as shown to perform tests easily.
lOpen harness securing clip to make testing easier.
lUse extreme care not to touch 2 pins at one time.
lData is for comparison and may not be exact.
ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and body ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
