Hello all

I have a y2k D2 V8 which has permanent traction control (I believe?). Is there actually a way of turning this off? I think I recall someone saying something about removing a fuse but I can't see one specifically for the TC?

Any ideas?

Hi there FN, when you say "permanent Traction Control" what do you actually mean?

It would be accurate to say that the turning wheels are always monitored for losing grip and under those circumstances the TC would come into operation to regain traction.

Do you want to stop this happening? If you do, you will also lose your abs and Hill descent functions as well - is this what you want?

Perhaps if you were to say what you want to achieve, you might get more useful responses.

generally its advised when setting off in icy/snow that it can help traction on traction controlled cars to turn the traction control off as it then allows wheelspin, which in turn creates heat which can melt ice,
I think thats what he's after
 
That's right...if I get into a situation where turning TC off is recommended i.e. snow, how do I do it. I thought it was the fuse but in the manual, it doesn't say which one to remove to do this.

I'll try the ABS one - in the manual, it says 'ABS Valve'. Sound like it's the right one?
 
dont have this problem on the defender, just good old fashioned mechanics not electrics, but from experience with other cars, you turn off the stability/traction control but that leaves the abs operational,
dont think its recommended to disable the abs, insurance may not like that
 
I believe it's more applicable to rear wheel drive, and particularly the ones with ESP stability control as it mentioned in the owners handbook of my wifes car, which is rear wheel drive.

As a newish 4x4 driver perhapes looking at this link may help u. 4x4 driving - snow & ice
 
If we're talking about driving on ice then the only thing that will work correctly, and allow the TC to work at all - is the use of winter tyres.

The rubber mix for summer and all-season tyres is completely different to winter tyres. Below 7°C the other tyres rubber goes hard and will not offer any form of grip, whereas winter tyres are chemically formulated to offer increasing amounts of grip as the temps descend.

This means safer motoring in dry, wet and icy/snowy cold conditions.

As for un-plugging the TC function on ice to melt it - well that just doesn't sound logical at all.
 
Agreed...i don't think it's to melt it...but I thought the idea was that although the wheels are spinning, if you ever get stuck (snow/mud/etc), having some drive was a good thing i.e. turn off TC and gently try to get out.

For those of you had are able to turnoff your TC...why/when do you do it?
 
traction control helps get traction by stopping the spinning wheel and giving drive to the wheel that has traction. Turning it off will just spin the wheels without grip, then you are stuck

ive seen it try each wheel in turn on a laning trip on a later 110, it onlly had to climb a 4" step but the driver wouldnt give it any revs so the traction control tried every wheel and couldnt get over the step, he only needed a little momentum, and that is without ice,
the problem it has is it cant handle no wheel having adequate grip, and doesnt give them long enough to find any
 
it doesnt "try "wheels ,it just applies the brake to any spinning past a given difference in the ecu its just electronic fiddle brakes

So why have the option to turn it off?

there is no such built in option... you can turn it off only by "altering" the system...the TC is a good enhancement cos it will try to keep the wheel's spin similar...it just applyes brakes on the whell which spins faster to equalise the torque...read the quoted part from the manual then think if you want to disable it or not
"RAVE"]ETC(electronic traction controll)
The ETC function uses brake intervention to prevent wheel spin and maintain even torque distribution to the wheels.
ETC is automatically enabled while the brakes are off at speeds up to 62.5 mph (100 km/h), and operates the brakes
either individually or in axle pairs:
l At speeds up to 31.3 mph (50 km/h), ETC uses individual brake intervention to maintain even torque distribution
between wheels on the same axle.
l Vehicles up to 03 model year – At speeds between 0 and 62.5 mph (0 and 100 km/h), ETC also uses brake
intervention in axle pairs to maintain even torque distribution between the front and rear axles. In effect, this mode
of operation replaces the centre differential lock of the transfer box which, although still incorporated, is non
operational under normal driving conditions.
If the centre differential
lock is in the locked condition, the SLABS ECU illuminates the ABS and ETC warning lamps and inhibits the ETC
function (the ABS, EBD and HDC functions are retained, but at degraded performance levels).
l Vehicles from 03 model year (with differential lock fitted) – At speeds between 0 and 62.5 mph (0 and 100
km/h), ETC uses brake intervention in axle pairs to maintain even torque distribution between the front and rear
axles. If the centre differential lock is in the locked condition, the differential lock warning lamp in the instrument
pack is illuminated. The ABS, EBD, ETC and HDC functions are retained, but with revised parameters to suit the
locked differential.
While the ETC function is enabled, if the SLABS ECU detects a wheel accelerating faster than the average, indicating
loss of traction, it operates the ABS modulator in the active braking mode. Depending on the vehicle speed, active
braking is employed for either the brake of the affected wheel or for both brakes on the affected axle, until all four
wheels are driven at approximately the same speed again. During active braking the SLABS ECU also illuminates the
ETC warning lamp, for a minimum of 2 seconds or for the duration that ETC is active. ETC operation is desensitised
during 'hard' cornering.

James, im aware of how it works, but have also seen the limitations of it where a difflock would of been better, or even a spinning wheel

3 locked diffs is hard to beat ,but its better than just cdl ,momentum is the essence of any poor surface driving
