New Prado traction control vs ARB Air Lockers

[physh]

Hi all,

A friend is considering a VX or Grande Prado TD, and these come with the Toyota "DAT" ("Driver Assist Technology" whatever that means) which includes a traction control aid which uses the brakes to stop spinning wheels.

Problem is - it only does so for a limited time (15-30 seconds from what I hear) due to the fact it only uses energy stored in the system.

What I want to know is, can I put ARB diff locks in, such that the diffs can be manually locked in the hard(soft?) stuff, but retain the functionality of the TC on the road in slippery conditions?


TC would detect wheel slippage from the ABS sensors and apply brakes as required.

I would think that the if the ARB diff locks are engaged, means all four wheels are rotating at the same speed - means no difference in speeds = TC doesn't see a difference and doesn't kick in!



So... Am I going barking mad, or is this actually workable?

Cheers
Nick

Diff lock's won't affect the traction control at all.

Check the owners manual

in my 100 series a lot of things are automatically deactivated once the centre diff lock is ingaged,i thought tracktion control was one of these.

That kinda defeats the purpose of TC doesn't it?
You put it in L, and centre diff locks by factory default.
If the TC disables, then what's the point of having it for climbing hills?

That's what I'd hope, but wondering if anyone has seen it done, or done it themselves??

You are correct - if you put in a diff lock onn the rear diff the TC will not activate when the diff lock is on - as u have said as both wheels will rotate at the same speed so the system will not detect slip - the TC will still work on the front wheels and it will also work when the diff lock is off.

The two are a good mix as the TC will provide max traction in lighter going and when needed the diff lock will cover the heavy going.

From experience, most factory traction control systems are pretty garbage in serious offroad anyway. Or on the beach, when you want a bit of wheel speed they activate and bog you whilst overheating the brakes at the same time.
As traction control opperates by sensing difference in wheel speedif all 4 wheels are locked together, you should be right.

Cool, if it works that'd make for a much more capable vehicle.

ARB have confirmed they can do (and have done) front and rear air lockers in Prado VX and Grande models with traction control.

It works perfectly and does not affect the functioning of the factory systems.

For the price of a Grande you can get a Disco 3 HSE. (Well $4500 more anyway)

If I wasnt scared I would break the thing it would be my first choice.

If only there was some decent choice for a solid axle.
