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?

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.

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.
