DSC cutting in too often one way only.

[Glynhouse]

My DSC comes on in a right hand corner far too early !

When "she" is not in the car I cannot get it too cut in at all without being silly, but up and down the Kuranda range just driving along with her in the passenger seat it cuts in on right hand corners for no reason, not every corner not even every trip just now and then, it sounds awful, like a flat tyre on the outside and the light flashes on the dash, certainly gets your attention.
If I hit a corner too hard with the van on it does or at least has come on turning both ways - I try not to do that !

Have not spoken to the service folk yet thought I would ask here first, just come back from a quick trip Cairns to Townsville and back no probs but then there are not any corners on that road, no van.

Any suggestions ?

Check tyre pressures, wheel alignment and steering sensor calibration. Unless you've bent something, it should be one of those.

Is it DSC cutting in or Traction Control cutting in because you are going around right hand corners a bit too quick :o and lifting an inside wheel.

+1. I had the issue once in my D3. Turned out i had a nail in the rear left. Tyre repaired, and issue stopped.

Check your shock absorbers.

If lifting an inside wheel, I'd hate to see how high the outside ones are:):):)

Try running your hand around your tyres to see if one has gone out of round , Sounds exactly what I had happen and one rear tyre had a large bump or egg in it . put spare on and fixed

Another vote on checking tyre pressures.
D3 will do this if you have an under inflated tyre such as a slow leak.

:eek: i would've thought that would be the first thing to look at !

No idea, but I can't make it happen by "pushing", occurs when driving reasonably sedately.
Was doing it with the 18"'s on still doing it now with 17's on tyres pressures are fine.

How do you tell wether it is traction or stability cutting in ?

Is the steering wheel off-centre when driving in a straight line?

When DSC kicks in it is often violent as brakes are applied to correct the slid - the whole car moves. With TC you will see the indication on the dash and the ABS type shudder can be felt and heard through the brake pedal.

I can get my TC to activate at an intersection near home where I turn right 90 degrees and the weight of the vehicle transfers to the outside and the inside lightens up cause a little wheel slip as power is applied and TC responds.

Having said that I have DSC activate on the road on tighter bends when I had a rear passenger side tyre deflating that was not obvious when driving.

There is a simple test - have you tried driving in the areas that cause the issues with DSC turned off?

Try driving in a straight line at a fair clip (80-90kph) & let the steering wheel go, keep your hands ready to grab it.
If the car just gently goes to the left with the road camber it's probably not tyres or alignment. If it goes right or left quickly then it could be tyres, alignment, something bent, worn bushes etc.
I do this all the time & most of the time the car tracks either dead straight or gently goes left, even over bumps & stuff.

Check your shock absorbers.

Do they wear out often? I was thinking about replacing the air spring/shock assemblies on mine, because it seemed drive kind of funny when I attempted to tow my 90 on a trailer. But it was the first time I've ever towed anything, and I very well might have been going too fast ;)

I've got over 290,000km and I was going about 110-115 km/h (I had to convert those, so hopefully I got them right.... the US still teaches us to think with silly units that no one else uses anymore).

Hi Dennis,

Our D3 used to have the DSC come on repeatedly when the shocks were crook. Might be time to fit a new set of front shocks as well.

[KOOS BEST]

Had exactly the same problem, eventually took the rear wheels off and then saw one of the the tires are not round anymore, were busy delaminating. Replaced the rear tires then all well.

Check tires are not out of shape.

Also found the left rear brakes were shot, it does not have a sensor for wear only the RHS has, check that as well.Maybe this was due the LHS wheel had to brake more because of the DSC

If you're on the original shockers they are way past their useby date!

If you're on the original shockers they are way past their useby date!By more than 200K on the roads around here where by 65K my OEM D3s were totally useless.
