Traction Control

[Kgee]

2000TD5 with CDL connected.
Has anyone got a diagram to fit a switch which would allow me to engage or disengage the Traction control as required with the CDL engaged.

Thanks

I'm confused....Why would you want to disengage TC when the CDL is engaged?

TC activates the brakes. Brakes slow you down

G'day Kgee,

I haven't heard of a switch for disabling the traction control as such, but a procedure.

Something like engage the CDL, turn off the car, turn the switch to ignition and pump the brake pedal 10 times in 10 seconds...

Do a search on "disable TC" or "disable traction control" on the forum, adnic posted a similar question recently.

EDIT: Read through this thread (http://www.aulro.com/afvb/technical-chatter/47978-turning-off-traction.html), should shed some light

I'm not sure if that works for the Disco2.

I've tried it everywhere on the D2, and there isn't a place that I could find where you are better of with the ETC disabled unless there is something wrong with your tyre pressures. At worst it makes no difference, at best the ETC will help you.

If you restart a pre MY03 facelift with CDL locked then it deactivates traction control, though normally the playing with the electronics is done so that you can restart with CDL locked and not lose ETC. I can check if you like, but the easiest mod is to interupt the CDL light wire that comes off the transfer. I don't recall the colour code for it, though I'm sure it had brown as either the insulation or the strip. To find it, lock the CDL so the dash light comes on, then unplug the wire on top of the transfer near the CDL lever. It's one of the two there. When you find the wire, add a momentary off switch between the the transfer and the wire and mount the switch up at your dash somewhere. With this setup, when you start with CDL locked you can just normally start and have nno ETC, or hold the button in and start with CDL. Using the momentary off switch will maintain the CDL dash light on your screen.

To disable, I would have thought that an in-line switch with the fuse would do the trick. However, I'm not sure if the system would like it when it was re-connected.

I can think of one reason to turn off TC. In sticky mud you need to spin the wheels to clear the treads.

On a D2 you can remove the ABS pump relay, or insert a switch in the relay coil circuit. In either case, when the relay is re-installed or the coil circuit switched back on, there are`no problems after the next engine (actually ABS ecu) restart.
Been there, done that and then got rid of the switch due to having found ABS & TC are better than no ABS or TC.

Just boot it, it'll still spin if its that muddy or clay, but the etc is still shifting power around

That would still work with TC... Boot it and you'll find that the wheels will quite happily spin up. (What you'd end up with is 4x wheels, all spinning at the same speed coz the TC can't detect that there's a problem.) :p

The best way to use TC is to feed the power in gently so there's just enough to get a wheel slipping but not too much... When the TC kicks in & sends the power to the wheel with traction, you don't want too much power going down otherwise you'll just end up spinning that wheel too. Also, when it starts slipping, keep the throttle steady & don't back off (yet), you need to give the TC time to work things out.

that there's not much point in turning TC off because "it's brakes that slow you down". Correct me if I'm wrong; the traction control only works on the wheel that has lost traction, hence spinning and wasting power. By braking that wheel, the power is re-directed to the wheel with traction, thereby enabling the vehicle to continue moving. As soon as the spinning wheel returns to a certain ratio with the other, the brake pulses are ceased. There is no "dragging wheel" so why you would want to turn it off, apart from maybe some vehicle hotted up to do "burnouts" :eek: I don't understand? I love a bit of fast driving, and turning it off seemed a silly idea... you would go slower not faster?

I was pretty impressed with my traction control on the beach at Cape Riche.
We went fishing,and drove onto the beach without airing down,with the thought that if we cant get off we will air down.Jeffs D3 and Phils D2 dug themselves in,Graz and his 130 and my D2 were ok.The other 3 aired down to get off the beach and drove straight out.
I kept the highway pressures,simply went back and forward on the track I made before I parked to get going.She was digging in but kept on going,the TC light only came on when I applied too much right foot,back off a tad wheelspin stopped and I gained momentum.
Not a thing I would normally do but we had plenty of vehicles to recover with if I did get bogged.
I feel the only time the TC is a hinderence is getting going in soft sand and when you are towing a trailer in boggy conditions with the CDL unlocked.

go to this link and the last part details the wire to cut or put a switch into

Like Slunnie says, after retro fitting my CDL I have yet to find a situation where you don't want TC.

Hi all
Thanks for the input like most I do not think there is a need for turning off the TC but was just trying to avoid the fact that it turns itself off if you leave the CD locked and turn off the engine. Slunnie your suggestion for the switch on the CDL light will overcome the problem.

Thanks again all
