TC is Traction Control, it's what makes the freelander so capable even to a complete novice, when you get wheel spin it operates the brake on the spinning wheel to apply torque to the wheel with traction so that you make progress where you would normally be left spinning a wheel (or 2 on a 4wd), so when you apply the brake yo stop all the wheels including the spinning one, so under what circumstances is it coming on?? Just coming on by itself randomly, or are you driving on snow/ice/some other slippy surface, or is it Just not extingushing at startup/bulb check?
Also, what is it? 1.8, L series doozel, TD4, V6?? Age??
