I bought landcruiser ute mining the transfer case is lock i can drive only 40km/h because ute used to work under ground mining the original linkage is not any more is that cost me a lot?

Does placing it in neutral put the entire drive in neutral???? Yes . Taking the vehicle to a qualified repair shop that has a factory or professional scan tool to read code's in the transfer case control module is what you should do , you probably have no clue of the complexity of these 4X4 systems . How many buttons on the switch on the instrument panel ?
The BW 4493/4494 transfer case features a 4-button shift control switch (1) located on the instrument panel. When the vehicle has the ignition key in the RUN position, the transfer case shift control module starts monitoring the transfer case shift control switch to determine if the driver desires a new mode/gear position. At a single press of the transfer case shift control switch, the lamp of the new desired position begins flashing to inform the driver that the transfer case shift control module has received the request for a new mode/gear position. The lamp continues to flash until all shifting criteria have been met and the new mode/gear position has been reached, or has been engaged. Once the new mode/gear position is fully active, the switch indicator lamp for the new position remains ON constantly.

During normal driving situations, the transfer case operates in the 4HI mode. When the 4HI mode is selected, the transfer case shift control module sends 12-volts to an electrical motor, which is the transfer case encoder motor. This motor rotates the transfer case shift detent lever shaft which moves the shift forks and range sleeve to obtain different modes/ranges.
The BW 4493/4494 transfer case has the added feature of also providing the driver with 3 manual mode/range positions:
• 4HI - 4-Wheel Drive High Open
• 4HI Lock - 4-Wheel Drive High Locked
• 4LO Lock - 4-Wheel Drive Low Locked
The driver may choose to select any of these mode/range positions while driving the vehicle. However, the transfer case will not allow a shift into or out of 4LO Lock unless the following criteria has been met:

DTC B0790 Transfer Case Neutral Indicator Circuit Malfunction
DTC B2725 ATC Mode Switch Circuit Malfunction
The mode switch circuit consists of 5 modes. The transfer case shift control module supplies a regulated 5 volts, DC to the switch through the 5-volt regulator circuit. The current travels through the resistor of the currently pressed mode button. The current is then returned to the transfer case shift control module through the switch signal circuit.
The transfer case shift control module constantly monitors this signal voltage to determine the condition of the mode switch circuit.
When each of the modes are selected they will complete a circuit through their own specific resistor while the button is pressed. The transfer case shift control module continuously monitors the switch input to determine whether the Neutral, Differential Lock, 4HI, 4HI Lock, or 4LO Lock mode was selected by the driver.

DTC C0306 Motor A or B Circuit Malfunction
The transfer case motor is a bi-directional, permanent magnet, D.C. motor. When energized, through motor control A or motor control B, the ground is provided by the opposing motor control circuit and then grounded through the transfer case shift control module ground circuit, the motor, through a series of gears, rotates a shaft which moves the mode and range forks to shift the transfer case between the following ranges:
• 4HI
• 4HI Lock
• 4LO Lock
• Neutral
This DTC detects an open, short to voltage, or short to ground in the motor control A or motor control B circuits, or an open, or short to ground inside the motor.

DTC C0327 Encoder Circuit Malfunction
DTC C0329
DTC C0359
DTC C0550

The Borg Warner (BW) model 4493/4494 NR4 transfer case is a 2-speed, full-time 4WD, transfer case. The transfer case has an external planetary type differential, which has 2 different sets of pinion gears. The planetary differential provides a 40/60 torque split front/rear full-time. This means the front and rear propeller shafts are constantly being driven for maximum traction in all conditions. A high/low planetary carrier assembly provides the high and low ranges, which is a 6-pinion gear, sun gear, and annulus gear arrangement, giving a 2.64 low range reduction ratio in the BW 4493 and a 4:1 ratio in the BW 4494.

DTC C0321 01: Transfer Case Lock Circuit Short to Battery
DTC C0321 02: Transfer Case Lock Circuit Short to Ground
DTC C0321 04: Transfer Case Lock Circuit Open
DTC C0321 08: Transfer Case Lock Circuit Signal Invalid

The transfer case shift control module controls the transfer case lock solenoid.
The transfer case lock solenoid is released by being energized. This is accomplished by grounding the lock solenoid control circuit during gears shifts, and in the AUTO 4WD mode. Locking action is applied when power or ground are taken away from the lock solenoid, the transfer case motor is prevented from moving. The system is capable of providing a 2HI, 4HI and 4LO lock-up without the need of additional vehicle power to hold the transfer case in these positions.
This DTC detects an open lock solenoid coil, open motor lock control circuit, or an open batter positive voltage circuit, or a short to voltage or ground on the lock solenoid control circuit.


Circuit/System Testing
The battery positive voltage circuit and the lock solenoid control circuit must be tested for opens, shorts to ground, shorts to voltage, and high resistance. This can also result from a electrically faulted solenoid.
With the ignition on check which DTC is set. If DTC C0321 is set with failure type byte 04 then do the following.
? The transfer case lock is unable to hold during a hold test and the transfer case actuator will need to be replaced, and the motor learn procedure performed. If this is not the case continue to the next step.
Disconnect the transfer case actuator, turn on the ignition and with a DMM check the battery positive voltage circuit for battery voltage at the transfer case actuator.
? If battery voltage is not seen then repair the battery positive voltage circuit for an open or high resistance. If the circuit checks out proceed to the next step.
Disconnect the transfer case control module connector X2 and check the circuit for an open, high resistance, short to ground, or short to voltage. If condition is found repair the circuit or inline connector 109 as necessary, if the condition is not found refer to component testing.

could be the clutch locked or the gear case... have a couple of strong friends ROCK it back and forth while you push the lever back to neutral..... dont push the clutch in while this is happening worth a shot!!

is the 4WD in the transfer case locked in to drive the front diff.

what are you lamps doing, 4wd/awd lamps.????
working FSM free, no book?
no online account at alldata.com?
in the FSM read the section called.
transfer system and inspection there.
4wd and AWD
transfer shift motor>? checks
NEUTRAL POSITION DETECTION SWITCH
CENTER DIFFERENTIAL LOCK DETECTION SWITCH
if the lamps, show its locked and you have it off
then it is locked,
and the motor failed or the controls to it failed.
the FSM covers all this and is not simple by any means.
i drive jeeps, and mine are all manual.
the fsm has a table for failures.
here is yours?
Does not switch to neutral?
CAN communication system (scan the PCM for errors)
Four wheel drive control ECU
Transfer position switch
Transfer shift actuator
Transfer faulty

there are 6 switches
4wd ECu
and the motor. to make it happen.
SCAN it.

Disconnect the Manual Lever and turn it by hand, if you can not... then you may have a failure of your Transfer Case.

check transfer and transmission oil

Hi, it sounds like your front diff engages but your transfer case is not. raise one of your front tires off the ground and see if it will lock up when you go to 4hi. If it does then the problem is your encoder motor that hangs down under your transfer case.

under the battey compartment is a lever that runs on vacume unhook the cable from the vacume plungger u will first have to take the battery and battery compartment out once u get the cable unhooked have someone start ur truck and then pull the cable under the battery box that goes to the 4x4 unit dont pull too hard u may pass up the sweet spot that locks in to 4x4 they may have to go to reverse to drive a couple of time while u r pullin on the cable itr will click forward bout a half inch when it locks in if ur 4x4 works after this u will need to replace the vacume plunger or do like i did and pull it till it locks in and tie it off to sumthin n go wheelin.... lol

The lights can come on wihtout the transfer case really working..the lights are actvated by a simple switch and only indicate the switch has been depressed.

It's sounds as if you have a problem with the lickage, or maybe damage inside the transfer case itslef
