VDC and SLIP light come on when it's cold...HELP!
 

For the past few days, every morning I drive my car my VDC and "SLIP" lights on the dash come on, and stay on. I always let the car warm up before driving, but as soon as I put the car in gear, they come on :icon27:. I tried turning the car off and back on at stop lights and that makes the lights go away for a few seconds, but then they're there again. Again, this only happens in the morning when it's cold outside. Has anyone else had this problem before? I figured there's no point in taking it to the dealer because they'll just tell me to bring the car in when the lights come on again. But by the time the service department is open, it's not that cold out anymore :icon31:. I need to go to the dealer in a few hundred miles for an oil change anyways, but I just wanted to see if anyone has had a similar problem with their Z.

And since you were nice enough to open this thread, I bring sammiches :yum: OP delivers!!!1!

:werd:

Oh and I thought my tire pressure might have something to do with it, but pressures are fine :dunno:

GOT THE SAME PROBLEM....... i think its ice buidlup in the abs sensor!! because i washed my car and my wheels with a pressure washer from the car wash and the problem stopped... try that out.. let me know if u fiure it out peace

Well it's a little cold in the mornings here, but I don't think it's cold enough for ice buildup. I'll look into it though, thanks! :icon38:

bump...anybody else?

I was just about to make a thread on this. Same thing happens with me, but not when its cold. It happens in the summer and in the winter.

Tonight I was driving and was in 3rd gear coming up on a light that turned yellow so I went WOT and shifted at about 4.5k into 4th.

I saw the BRAKE light go on for a bit, then both the VDC off light and SLIP light came on and stayed on.

For some reason whenever I go WOT, even if I shift early and slowly, this happens, and I can't seem to figure out why.

Car is a bone stock 2004 Z.

Ya my brake light comes on too when it's cold but usually goes away about 2 minutes after I start the car. I was at the dealer today and they told me that the cold weather throws the sensors off, which is why the lights come on. But it's weird that yours come on even when its not cold :confused:

when i had this problem it was my camshaft POS sensor.. you need to read the codes if you have any

Oh ya, never thought of that. I'll need to check where I can borrow an OBD2 scanner from. Thanks Doug!

I had this problem, with the Brake light also lit, and the dealer said it was an indication that my brake pads were low. I just had them replaced, and so far the lights are out.

Cold weather.
Brake pads.
Brake fluid.
-or-
Build-up on sensors.

Ok, I was about to start a thread on the same thing. This morning on my way to work I noticed that my VDC and SLIP lights were on (it was crazy cold here, only 10F). When I would approach a stoplight or had to come to a stop because of traffic the brake light would come on, then go off when I would accelerate again.

I checked the brake fluid; it's in between the min and max marker lines. The pads only have 18k on them and there is substantial amount of pad left. PLUS, the brake pads have their own warning light and they are equipped with the tab that squeals on the rotor when the pads are low.

The only thing about this morning is it was crazy cold out; there was no ice build up on anything, no frost, etc.

So when those lights come on when it’s cold like that, is the VDC actually not working, or are the lights just coming on?

Ok, just an FYI for this thread.

I was reading this thread here

and apparently, even if your brake fluid level is in between min and max that can still be the culprit, especially if your brake pads are coming to the last third of their life. Solution; fill the brake fluid to tha max line.

I got this tonight while driving on the highway. Also got the SES light as well.

Hey guys, thanks for the info... as you can tell I also have this problem, the dealership only said that it was an issue that needed to be looked at but to determine this they wanted me to pay an exagerated amount of cash just to tell me what was causing the problem. I'll try your suggestions first and see what happens.

Hmmmm....interesting. My light stopped coming on after I got new brake pads

Did you try topping off your fluid first? How many miles did your pads have on them?

No I didn't....I didn't think it would have anything to do with the fluids. I got 24k miles our of my rear pads. The fronts still have a little bit of meat on them

24k is good enough. Close enough to the expected 30k

I only have 19,200 on mine. So I know they aren't done for yet. Topping off the fluid worked for me.

Update: My issue was a code P0340 which was the Crankshaft Position Sensor. Dealership replaced it and did a reflash, but I had to pay out of pocket.
