Thread: Traction Control

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, 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
