We turn on the locks ... - Toyota Land Cruiser, 4.2 liter, 2007
One of the first questions to the old owner of my "weave" was the question of how the locks are turned on. The answer was rather chaotic, and it became clear that he rarely used all the advantages of all-wheel drive :-)
How to actually use them? I think many novice owners of TLC with a manual will be interested.
All control is carried out by the transfer lever (three positions - H normal, N neutral and L low), the center differential lock enable button (blocks the front and rear axles, i.e. at least one wheel on the rear and one on the front axle must rotate simultaneously. The button in my car is located on the center console on the left) and the rear cross-axle differential lock switch (when both rear wheels rotate at the same time. The switch labeled DEEF LOCK is located on the panel to the left of the steering wheel).
So, the usual position for everyday driving on both dry and slippery roads is the position of the transfer lever H. In this case, all differentials are unlocked. Those. theoretically, there may be such a situation: when slipping, one wheel can be stationary, and three can rotate.
The second position of the transfer case lever is neutral. At the same time, no traction is supplied to the wheels at all, no matter what gear we turn on at the checkpoint. This position can be used, for example, when working with a mechanical winch.
The third position - L - reduced. The sweetest thing for a Jeep :-) The position allows you to increase power and traction and is used in particularly difficult off-road conditions.
Switching from position H to L is carried out either when the car is completely stopped (which is recommended for beginners), or when the speed is reduced to 6 kilometers per hour. In this case, as well as when shifting gears, the clutch is squeezed out. Reverse switching is also performed with the clutch depressed, but this can be done without stopping the car.
Now about blocking. When the center differential lock button is pressed, the lock indicator on the instrument panel lights up.
The rear and front axles are now rigidly connected.
This position is used if the wheels slip heavily (ice, mud, etc.). It is not recommended to constantly drive on dry roads with the interaxle lock turned on (increased transmission and tire wear, increased (albeit slightly) fuel consumption, reduced handling). Engagement and disengagement of the lock can be carried out on the go without pressing the clutch. However, on slippery roads, when the wheels slip, it is better to do this by reducing the speed in order to avoid, at best, an unexpected skid when the traction on the wheels changes or, at worst, breakage of the cv joints or axle shafts. Although it is not known what is worse - the axle shaft or skidding into the oncoming lane ... In any case - be careful!
Locking rear cross-axle differential.
It is used if, with the center differential locked, the car still slips and cannot move (for example, wheels slip on the left or right at the same time). How to enable blocking. In the position of the transfer case L and with the center differential locked, we stop the car (if you try to turn on the lock in motion or brie skidding wheels, you can easily lose one of the rear axle shafts, especially if you have bad mud tires), squeeze the clutch and turn the switch clockwise. Let's release the clutch.
The red lock indicator should illuminate on the instrument panel. If the indicator blinks, the blocking has not turned on.
Switching off occurs in the reverse order, or automatically when the transfer case is switched to the H position (in this case, do not forget to turn the lock switch to the off position).
With the rear axle differential locked, it is not recommended to drive at speeds above 8 km/h. Manageability in this case is simply no. This lock should only be used when negotiating difficult off-road sections.
What else can be said about blocking ... Oh, yes. When the rear cross-axle differential lock is engaged, the ABS indicator flashes. Don't be afraid - it's just that in this position the ABS is turned off :-)
I believe that in cars where there is a front cross-axle differential lock, the algorithm for turning it on is the same as turning on the rear lock.
Good luck and all-wheel drive!

There is no 2H mode on TLC. Only permanent four-wheel drive. For me, that's good.
Agree…
Urich63
I have a 2H mode on the TLC-80, and the 4H mode immediately blocks the axles! But this mode is designed for short-term inclusion or driving on slippery and wet roads.
Not very good…

Big minus.
Thanks.
I looked through your blog, and I think how much potential is wasted (I'm talking about my car). If anything, I will turn to you for advice more than once, if possible?)))
The steering wheel spins like normal.
The button enables accelerated warming up of the engine in cold conditions and increases the speed.

Each drive type has its pros and cons. In my experience, I prefer permanent full.
Hello!
Can I find out, when you press the center differential lock button, can you turn the steering wheel or should the position of the wheels be even?
Also, what does the POWER HEATER button do?

Definitely.

I understand everything, and I agree, but you just said that there is no such regime on TLK. It turns out there is…
All hundreds only Full-Time.
TLC has a transmission with full-time permanent all-wheel drive (Japanese, Europeans), and part-time (Arabs) full-time
, permanent all-wheel drive with interaxal blocking part-
time like on UAZ, rear-wheel drive with a plug-in front axle
Plug-in all-wheel drive on a hundredths is rare. For example, mine doesn't. There is only a permanent full.

On the Pajero Sport New, despite the presence of an "automatic" box, almost the same locking algorithm is used, only the center lock is activated by the same transfer lever, and the rear axle differential lock is turned on by a switch on the panel to the left of the steering column. I just didn’t understand if there is a 2H mode in the TLC (rear-wheel drive only), Sport has such a mode and switching between 2H and 4H is possible at speeds up to 100 km / h. And it looks very similar :)

"Honest" blocking in the rear axle is cool, this is a serious jeep attribute. Usually people put them on during serious preparation of the car, but here it is in the state.
2 clarifications on the text:
>>>> All control is carried out by the transfer lever (three positions - H normal, N neutral and L reduced)
H is not normal, it is elevated, from English High.
>>>> So, the usual position for everyday driving on both dry and slippery roads is the position of the transfer lever H. In this case, all differentials are unlocked. Those. theoretically, there may be such a situation: when slipping, one wheel can be stationary, and three can rotate.
Here, the opposite situation may arise, i.e. 1 wheel is spinning and the other 3 are standing still. For example, if you lift a jack for 1 wheel, then it will be so. The moment walks in this position of the lever from wheel to wheel. Turning on the interaxle lock "turns on" one more wheel on the other axle, i.e. in any case, 2 wheels will spin, one on each axle. The inclusion of an interwheel lock in the rear axle is forced to spin in any scenario 3 wheels, both rear and 1 of the front.
And everything else is correct.
Appropriate clarification…

It was interesting myself, and therefore delved into the essence of the process)

I have a boss with a weaving, he says that he also has a blockage in the front axle ... a hundred, my dream. turbodiesel, 7 seats.
He probably has 105 ka...
My father also has exactly the same weaving, only black =) Initially, it was category D, converted to B. Like, the rear benches were removed)

Not only. On diesel engines with a gun, there are configurations with a rear locking differential. I have one.

By the way, not all acres have a rear block, I have only an interaxle lock on a gasoline VX with an automatic machine ... And this is not ice ...
The rear block is only on the handle ...

Miroslav, good afternoon! Thank you so much for such a cool article about Kruzak. We turn on the locks ... Just super! As a driver with a long experience, I wanted to clarify whether it is possible to turn the steering wheel when the center differential button is pressed? Will I break the bridge or axles? Since the former owner did not really tell me about it. And is it necessary to include L on the transfer case? Automatic machine. I will be very grateful to you!
With the interaxle lock turned on, the car obeys the steering wheel much worse. And if you still block the rear diff, then it’s a real disaster.
Instruction posted for download www.drive2.ru/cars/toyota...av32/journal/944276/#post
Of course, you can turn the steering wheel :-) Otherwise, how to drive?
The interaxle differential lock can be turned on in position H right on the go, but the interaxle differential lock is locked only in position L.
Neither the interaxle lock nor the interwheel lock is activated at the moment of wheel slip. This is where it can really break down.
The center differential is blocked, as stated in the instructions, with a loss of power. It is understood that this occurs when the wheels slip. Those. if it stalled or drove out onto a slippery surface, turn on the interaxle lock.
L is low gear. It can be turned on preferably when the car is completely stopped and only in case of a complete ambush)) Downshifting gives an increase in power. transferred to the wheels.
If necessary, I can send the instruction manual for TLK-100.

Thanks for the article) my parents bought the first (after cars) Pradik in a 95 body, but my father didn’t really know anything about all-wheel drive and lock control) now I’ve read a lot, figured it out with him :)
a dream))) but only with automatic transmission … I no longer consider mechanics.
Is it possible to turn on the rear axle block without blocking the center differential?
Yes buzzing, okay, I'll go to MOT. let them look there, maybe it’s just that the sensor doesn’t work that the hook has passed ...
does the motor make a noise when you turn it on?
but on asphalt it’s just not necessary, it’s useless. it is enough even to lift one wheel with a jack and twist it. it first spins, and then stops - it means that it has engaged with another wheel.
yes, I’m doing everything right, I recently bought a new locking motor, gave a lot of money (and the old one just fell off when they began to unscrew it), I think that the lock does not turn on due to the fact that it is slippery! (like there is no difference in the movement of the wheels when cornering) it is necessary try on dry pavement ... it's a shame to ride such a car without a block (
yes, the lower is L in the transfer case.
Everything is arranged in such a way that the center differential - yellow - is blocked even without a lowered one. But at the same time, the rear differential - red - will not block until the lowered one is turned on.
Interestingly, when you turn on the lowered, the center axle is blocked automatically. And after that, you can connect the rear lock. More precisely, you can turn it on earlier, but the wheels will not block. I myself thought that something was wrong with me until this algorithm found out.
If the motor hums, but does not block the wheels, there is a chance that there was a blow to the motor housing and the magnet broke off. It is repaired in half an hour - the case is disassembled, a magnet is glued and assembled back.
The lowering (as I understand it, L on the razdatka, right?) In my place, it never turned on at all, only on the go, you drive slowly and turn the steering wheel to the right or to the left.
Was the downshift turned on before? My rear diff only locks in low gear. and sometimes only when driving when there is a difference in the speed of rotation of the wheels.
I tried everything (the indicator flashes Krasnodar, and the lock does not turn on, although the motor is alive !, what else could be the problem?
At what speed with the included inter-axle differential can you move on TLC 100 4.7 with automatic transmission
We have different bridges in front, and therefore a different switching algorithm.
And I agree about the shutdown, I also try to turn it off slowly.
Good day! Very well written. I would like to add only about the locking of the front cross-axle differential - I have it, and it is turned on by the same wheel as the rear lock. That is, first turn on the back. And if necessary, you can press this wheel again and turn further clockwise to the next position.
What was embarrassing at first was that I turned on the lock, the motor buzzed, and the signal on the screen blinked. This means that the locked wheels rotate at the same speed, and there is no need to think about a malfunction. As soon as there is a difference in the speed of rotation of the wheels, it will immediately block, and the icon on the panel will start to burn constantly.
Removing the lock often does not occur immediately after the mode is turned off, but only when moving. At the same time, it seems to me that it is better to turn off the center differential when the car is stationary, or at least when the gas pedal is thrown. Otherwise, the load on the transmission does not always allow unlocking, or it does it hard, you can hear and feel a hard "hit" or something similar, I can’t describe it more precisely.
It is hard to say. If there were few sharp turns, then the damage was done to the rubber rather than the differential.
Yesterday I drove about 70 km with a locked center differential at a speed of 100-120 km.h on dry asphalt (I accidentally turned it on, but I didn’t notice the indicator, because it was blocked by the steering wheel) HORROR!
What do you think - badly damaged the car?
And if the rear axle lock does not turn on, what are the options? (we include everything according to the instructions)
Is it possible to damage the center differential so much that it begins to slip? For example, if the ride is always blocked. It's just that everyone says that the transmission is wearing out, but it is rarely specified what exactly wears out.

Good afternoon! Please tell me, when you press the center differential lock button, does it stick inside? Those. Does it have two positions - turn on and off? I have a trace. the problem is, the button constantly returns to its original position and there is no indication on the panel that the lock is on, but if I hold it with my finger, then after a couple of seconds an indication appears on the panel that the lock is on. The display button itself does not have a purely physical, I took it apart and looked. The car is 2006 4.2td, the button block itself is slightly different, I have a block of three antenna buttons, an emergency gang and a lock there.
The same nonsense, no reaction on the speedometer, nothing lights up when you press the button,

Good afternoon! I'm not a mechanic, and even more so, I have a manual transmission.
Good afternoon! Which fuse and relay is the inclusion of the inter-axle differential. And where to look for them? TLC-100 2003 automatic transmission. There is no guide. Thanks.
Hello, can you help me, I have such a situation, the differential lock does not turn on, and there is a metal-on-metal script when you go. Thank you in advance
Greetings. At what maximum speed is it possible to travel with a locked center differential? (Of course, in sand, mud, snow, soil)
This is a stability control lamp. When enabled, the lock is disabled. This is fine.
Hello, when you turn on the center lock, the VSA light comes on, is this normal? (American 2003 model year)
Mursal, I don't understand technology so deeply. It is better to turn to experienced technicians.
Hello, I have fierce and jolts when I press the gas and when the selector is switched, I thought that the transfer case was coming, I removed the universal joints (I have a spare transfer case from 5 mortar fits perfectly on the 4 mortar) I checked the backlash in the transfer case itself, the absolute backlash is the same as on donor, I think it means it’s not in the distribution case and not in the automatic transmission, then I put on the front cardan and voila, there are significant backlashes in the flanges on both sides, I think I can disconnect the front cardan altogether and move in the back while it’s dry, it wasn’t there that the car didn’t go without the front cardan , and only the front cardan was spinning, pressed the button, pulled the lever, nothing, they said that the lock button where the emergency gang and the antenna does not work, although when you press the button, I hear the relay under the driver’s feet on the left, this motor does not work, could you help me? ) motor on razdatka
