TD5 tc

Hi all, i wonder if anyone could please help, i was in my wifes TD5 disco yesterday and was in a lot of mud!! as i turned through the mud the traction control light came on and the front wheel area made a vibrating rattle?? anyone seen this before

The TC works by using the ABS brake system and is fully automatic . . when a wheel starts to turn faster than the average rotation speed of the remaing wheels the system applies the brake to the faster wheel, which causes the drive to 'transfer' to the other wheels via the differential !!

You will hear strange noises similar when it is operating, akin to a 'spring boinging', or a kind of tangy, rattle !!

This is perfectly normal . . . (well I hope it is, cos my Disco does it)

Also, (in case you didn't know), the TC system is more 'aggresive' or works harder . . . when in Low Range !! So, you may be in 1st gear HR, and not get through the goo as well as you will in LR !!!

Have a look at this to find out how the system works . . .Traction control system - Wikipedia, the free encyclopedia

That's Traction Control working as it should!

Sorry Steve, you beat me to it!

Great, thanks for the quick replies, puts my mind at rest, and of course my wallet, thanks to all

No probs M8

(you gotta be kwik in 'ere )

Try Hill descent control next ... find a really steep grassy slope, low range, first gear, set the HDC button, and drive over the edge .

Whatever you do, do NOT push the clutch down!

A bit of throttle will help her descend more quickly .... and someone said that the cruise control works in Hill Descent mode, but mine won't do it yet.

the DiscoII traction control is simply superb...the only downside to it, is the the noise it makes. Which is perfectly normal, nothing to worry about and actually quite pleasing once you understand what is going on ...and your car is still ploughing through whatever you are throwing it at ...

You will also find the same noise and sensation when you start her up, if you got your foot hard on the brake pedal. This is also normal as it is the TC computer (SLABS ecu)running through its power on self test.

Cruise control & HDC, not on Discovery 2, that came later.
On Discovery 3, Range Rover Sport, Freelander 2 and Range Rover since it gained Terrain Response, you can adjust the target speed of HDC using the cruise control + & - buttons.

Although not recommended, on Td5 HDC will work, for about 45 secs, if you dip the clutch, or even go into neutral! In other words it will protect you from your own stupidity!

Right .... thanks for that. I could not make it happen in the Disco 2 TD5.

I believe you, but I won't be trying it!
Well, maybe I will on a slope that isn't too steep ....

MORAL on steep descents: NEVER push the clutch pedal!
DO NOT try to change gear on steep slopes, up or down.

No it didn't - Cruise Control AND HDC . . ARE very much on the Disco 2, even the 'early' Disco 2's had HDC as standard.

ALL varients ARE wired for cruise, although the lower spec ones didn't have the switches fitted, VERY easy DIY fit (LR will tell you it is complicated, and will want around £300+ do do it for you) . . .

Well they would, woudn't they

As Charles said, it's a brave soul who presses the clutch on a steep descent HDC (or not) and anyway, why would you WANT to

Sorry, should have made myself clearer, the link between cruise control and HDC wasn't on Discovery 2. That was a Discovery 3 feature

I quite agree, but I did say not recommended, but there to protect idiots!

Try it, it helps build confidence in the vehicle, but all this technology is only there to help, basic rules still apply, gong down a steep hill, low range first, feet off everything.

Ah, ok . . when I re mortgage an get one, I'll let you know

Mind you the Disco 3 can do everything so I hear, it even makes T whilst going up a 1 in 1 slop (aparently )
