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.
●Open harness securing clip to make testing easier.
●Use extreme care not to touch 2 pins at one time.
●Data is for comparison and may not be exact.
ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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.

TROUBLE DIAGNOSIS
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.
●The 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.

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.
EFS001BT
1. USING CONSULT, PERFORM OR 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-II. (Malfunction is present in the 4WD system.)
2. CHECK USING THE DATA MONITOR FUNCTION OF THE CONSULT-II
●Perform inspection by the data monitor function of the CONSULT-II.
●Check that the operation is in AUTO mode.
●Measure voltage when the accelerator pedal is not depressed. (Accelerator pedal not depressed: Approx.
0.5V or lower)
●Measure 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 >>
●Not in AUTO mode. GO TO 3.
●Voltage when accelerator pedal is not depressed is higher than approximately 0.5V.
●E-TS solenoid valve current when accelerator pedal is not depressed is other than 0A.
●Countermeasure: 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.)
