NOIf this towing method is used, either from the front or rear: Never tow the vehicle using a method where the lifted-up wheel
cannot rotate.
Do not use the sling type towing method, either from the front or rear,
as this method causes damage to the body. (a) There is a danger of the drive train heating up and causing break-
down, or of the wheels flying off the dolly.
(b) In addition, if the vehicle is equipped with the Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, the system will apply the
rotating wheels brake unless the engine isn't shut off.

5. WHEN TOWING FULL-TIME 4WD VEHICLES
Use one of the methods shown below to tow the vehicle.
If the vehicle has trouble in the chassis and drive train, use method 1 (flat bed truck).
NOTICE:
Do not use any towing method other than those shown above.
For example, the towing methods shown below are dangerous or damage the vehicle, so do not use

(b) Inspect the system circuit with the connector discon-
nected.
Disconnect the connector from the rear diff. lock control
ECU and inspect the connector on the wire harness side,
as shown in the table.

If the circuit is not as specified value, check and repair or re-
place the trouble part shown in the table above.
(c) Inspect the system circuit with the connector connected.
(1) Turn the ignition switch to the ON position.
(2) Shift the transfer shift lever to L position.
(3) Using a voltmeter, measure the voltage when the
differential lock control switch is in the position, as
shown in the table.
