DRIVE LINE CONTROL SYSTEM (TOD)

Step

Action

Yes

No

1

1. Turn off the starter switch.
2. Disconnect the ECU connector from ECU.

Does the resistance between terminals (B–67)4 and (B–67)12?
indicate 1.0 to 5.0 ohm?

Go to Step 2

Go to Step 3

2

1. Connect the ECU connector.
2. Start the engine.
3. Set the TOD mode.

When the throttle is operated between full close and full open
positions, does the voltage between terminals 4 and 20 indicate at
least 0.1 to 1.0 V?

The phenomenon

is not

reproduced.

Refer to

“Troubles

intermittently

observed”.

Go to Step 4

The ECU has

failed. Replace

the ECU.

Go to Step 4

3

Does the resistance between transfer connector terminals (A–3)8
and (A–3)7 indicate 1.0 to 5.0ohm?

The harness is
broken. Repair

the circuit.

Go to Step 4

Replace the

transfer

electromagnetic

coil.

Go to Step 4

4

1. Check that all the parts are mounted.
2. Clear the trouble code.

Is this step complete?

Repeat the

“Diagnosis Flow”.

28

The shift on the fly system (front

hub) works incorrectly.

NOTE: The shift on the fly system is not changed
between 2WD and 4WD modes normally.

CAUTION: If code 32 or 33 is also observed, remove
the trouble associated with code 32 or 33 first.
