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–49)11 and (B–49)22
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 11 and 22 indicate
at least 0.1 to 1.0 V?

The phenomenon

is not

reproduced.

Refer to

“Troubles

intermittently

observed”.

The ECU has

failed. Replace

the ECU.

Go to Step 4

3

1. Disconnect the connector (M–27).

Does the resistance between transfer connector terminals
(M–27)8 and (M–27)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 (P1760)

The shift on the fly system (front

axle disconnect) 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.

DRIVE LINE CONTROL SYSTEM (TOD)

Step

Action

Yes

No

1

1. Turn on the starter switch.
2. Set the transfer to the 2H mode.

Is the battery voltage observed between terminals 23 and 46?

Go to Step 2

Go to Step 5

2

Is 5V observed between terminals 42 and 46?

Go to Step 3

Go to Step 6

3

1. Set the transfer to the high (TOD) mode.

Does the voltage between terminals 23 and 46 indicate 0V?

Go to Step 4

The ECU has

failed. Replace

the ECU.

Go to Step 7

4

Does the voltage between terminals 42 and 46 indicate 0V?

The phenomenon

is not

reproduced.

Refer to

“Troubles

intermittently

observed”.

The shift on the

fly system is

failed (refer to

Section “Drive

Line Control

System” and

“Front Axle”).

5

Does the TOD indicator show the 2H mode?

The ECU has

failed. Replace

the ECU.

See “Trouble

Diagnosis

Depending on

The Status of

TOD Indicator”.

6

Set the transfer to the high (TOD) mode.

Does the voltage between terminals 23 and 46 indicate 0V?

The shift on the

fly system has

failed (refer to

Section “Driveline
Control System”).

The ECU has

failed. Replace

the ECU.

Go to Step 7

7

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

Is this step complete?

Repeat the

“Diagnosis Flow”.
