Thread: Is my Traction Control working???

TC does have an "I give up point" hard to find with a manual (you'll stall) but if youve got an auto you can find it. it will also shut down from overheating of the pump if you work it stupidly hard for an extended period (its around 10 minutes of constant use)

and yep the TC light comes on when its working and when its got a fault, if its got a fault it stays on permanant and if its working it turns off about 10-15 seconds after TC has stopped working.

The traction control makes the noise that it’s supposed to; I know this after reading the following thread… Traction control noise

My first question WILL be easy. When I hear the traction control noise I see the “TC” light illuminate in my instrument panel. Is this telling me that it is working, or that it’s broken?

My second question may be more difficult to answer over the net. I have experienced what I think is called “axle twist”, where for example my front left wheel and rear right wheels are in the air, while the front right and rear left wheels are firmly on the ground. Sadly for me the only wheels that were turning were the ones on the air. I was quite stuck when you consider the only recovery gear I had was the standard jack (it’s now very muddy…).

The other incident that raises this concern was when trying to pull another 4WD out of a bog. Only two of my wheels were turning while the other two (on opposite corners) were spinning, slowly digging me in.

Is this a malfunction or am I driving the vehicle incorrectly? Any suggestions would be appreciated.

Milney

You found the limitation of TC. With two wheels suspended and no CDL engaged, TC has an issue performing its calulation of average speed. So NO, it's not your driving it's a limitation of the pre CDL DII. This TC stuck scenario also occurs when two wheels on the same axle alernatively slip whilst the other two wheels are securely on the ground such as on a very steep incline. You need to consider fitting a CDL actuator to use CDL, it's a totally different vehicle especially when TC kicks in.

.

The TC light will illuminate when TC is in operation, if the TC is only momentarily engaged the TC light will still glow for 4 seconds.

I do not have the CDL actuator (It can be locked manually on my '99 D2 somehow), but will be getting one installed eventually. This will be an important backup for when the "3 amigos" return (TC, HDC, ABS warning lights all on) as I'm sure they eventually will.

Thanks for that guys. I was a bit worried, I've only had the vehicle since just before Xmas and just spent $630.00 to replace the Injector wiring loom (that was a saga). I'm most pleased I don't have to spend money on a TC repair. Now to the phone to find someone to supply and fit a CDL actuator...

Much appreciated,

Milney

Electronic CDL actuator can be installed where the switch is mounted in place of the coin tray. (Applies to your D2).
The guys at "All Ranges" in Bayswater on 9762 2600 mentioned it to me last week. Talk to Jamie, I'm not sure if they do the work or were reccommending someone. I was too busy looking at my new General Grabbers and forgot to listen.
If you find out who and how much can you PM me the details.

If your in that situation again where you are sutck and you dont mind getting dirty you can actually engage the diff lock with a 10mm spanner (i think). The spigot to engage the lock is on top of the transfer case and you just need to get under and reach up and around to get the spanner on it.

Its difficult but it works. Its just a pain in the ass.

Yes 10mm spanner

And yes pain in the arse but worth it

Baz.

And yes, very dirty......
Before climbing under the Disco make 110% sure it's safe to do so, make sure there is no chance of the vehicle moving in any direction while you're under there. That would include sinking further if you're bogged in mud
