Has this car got Traction Control?

Operating at 7 sec and 35 sec?

Seems that it might have but I am not sure - any thoughts?

35 Sec... Yes.
7 Sec... No... They gave up before it had a chance to do anything.

Interesting, that is what it looks like to me too. The thing is I am pretty sure this is my car and it now definitely doesn't have TC. Can it be disabled / removed?

Would that be traction control, or diff locks. Or are these one and the same?

Different - diff locks mechanically lock the, er, diffs and TC uses the ABS system to brake the wheel that is spinning thus forcing the lazy wheel to move.

Yes,
But I meant has the Land Rover got TC, or has the diff locks been engaged for his second attempt at the hill?

Definitely no diff locks.

Question mark over TC but as Camel Landy observes, it looks like it.

No cross axle lockers as std, but from the lack of acceleration/decceleration of the front wheel it has had some fitted (generally "ABS" psuedo lockers rely on sensing quite a large differential speed across an axle before they operate (to avoid them coming in too soon and actually impeeding progress as the wheel is braked) However one caveat, is that sometimes the frame rate on a video can actually make a spinning wheel look stationary (aliasing effects).

looks like a puma defender so it will have traction control as standard. didnt look like it had lockers at all in either part. if it had lockers then you wouldnt see ANY "spin up" of the wheel which has left the ground as it would still be travelling at the same speed as the wheel on the other side.

It's a 'Puma' engined car... It'll almost certainly have TC and it definitely does have a centre diff lock.

I think it is the car that I bought. It is Puma engined but does not have TC or ABS. My query is could it have had these in the past and since had them disabled?

[camel_landy]

It's a possibility...

...but how do you know it hasn't?

i think the front left wheel spins up momentarily when the front right wheel looses traction in the step up? This would happen with either real lockers or electronic ones, as the system tries to balance the speeds across the axle. However, i still think the changes in wheel angular acceleraton look too steep to be an electronic locker (the ABS pressure control values system has a limited response rate, typically about 3-5Hz at low speed)

im not sure; it looks to be spinning and then stopping like it would if the ABS/TC kicked in. Could also be the frame rate of the camera etc etc. Hard to tell, but when you see video of vehicles with lockers (ones which completely lock like ARB etc) then it looks much more controlled without spin up. see these vids

Crazy idea

Have you opened the bonnet to see if it has an ABS pump?

The standard Defender doesn't have diff locks on the axles but it does have the ability to lock the gearbox diff, so meaning the front and rear axles are locked together and the wheels turn at the same speed.

The TCS was an option on TD5's and the 2.4 Puma's (not sure on the 2.2's but probably the same). So some don't have it.

BTW - when you say it's your car - do you mean you're exact vehicle in the vid, or just one that looks the same?
