Traction Control Anti Slip ISSUE
 

So a while back I had an accident and the damage was on the front passenger wheel. The ENTIRE wheel hub, spindle, rotor, caliper, brake line, abs, wheel was snapped off the car. Well since then the car has been repaired and just had an alignment done on the car with my new set of 20's. So my issue, the light is still ON and the VDC button wont respond but light remains on as well. Any way to fix this issue?

HOpefully that gives you enough about the topic.

The same thing happened when I had my last accident in my car. I drove over a tire shred on a highway ramp (in the rain), slid onto the grass, and then bumped the guard rail. The slip light and the VDC light stayed on after it happened, but they went away after I turned the car off and started it back up again.

I was hoping it would go away but unfortunately it hasnt. Since I had to replace the entire wheel assembly on the front passenger I wasnt sure if something was missing like a sensor. Also find it weird the traction light is on as I figured the rear would be the one to affect the light

Maybe you could try disconnecting the battery to clear them?

oh its been disconnected several times and replaced. Is there a traction/antiskid sensor in the front passenger wheel?

I bought a AbS sensor off ebay, do I need to program it or anything? thats the only sensor I am aware of.

This will happen if the controller isn't getting a signal from all the wheel speed sensors. So are you seeing the "VDC Off" and the slip light and the ABS light? Or just the VDC off light by itself?

you need to take it to a dealer and have them hook the consult machine up to it to see what the problem is. I recommend SUtherlin. Mine was a piece of track rubber in between the hub and the sensor

The abs light is not on... Just the vdc light and the Losing traction icon light is on. Which hub would have the sensors the ones on the back? Because the front passenger is completely new but never bought a sensor other than abs. The rest of them have had new struts, springs, rotors and pads installed so I would think setting stuck would have been seen.

anybody have a picture of the speed sensor? Also do all the wheels have the speed sensor? I thought the only wires i saw were related to the ABS, which isnt on.

It's the same sensor for both. All 4 wheels have the wheel speed sensor which is used for ABS and traction control.

I replaced the ABS sensor for the FRONT PASSENGER wheel. Since it was not the same sensor that came on the car should I have to program it or anything??? The ABS light was on previously and since the sensor was installed the ABS light went off but the 2 others remain.

No programming is required. I would check the controller that is under the plastic cover near the e-brake and make sure that it has power.

May not be related but are you low on brake fluid?......

Brake fluid has been replaced even new brakes. The whole car went through an overhaul. But what I'm trying to understand is what the speed sensor looks like. Anybody have a picture of it on the front passenger wheel? I would love for ever Eva. :)

Don't have a camera handy but I just had mine off for a repair.

The wheel speed sensor is a black cable with red stripe, it connects to the steering knuckle/spindle and magnetic pick up portion penetrates partially through a small hole. The hole is on the opposite side to the brake caliper. The cable runs up the spindle and back to a connector that is behind the plastic splash shield.

I would think that the wheel speed sensors are working correctly though if your ABS light went out.

Double check your brake fluid level, wheee! is correct that if the level is anything other than max it can trigger this condition, although I think the e-brake light comes on as well if I recall correctly.

Any updates Billet???

Havent checked yet but we just flushed the brake fluid and changed all the rotors and pads so when that was done all was fine.


IF i had a picture of the sensor that would be SUPER HELPFUL. Just tell me this so I completely understand THE ABS SENSOR and the SPEED SENSOR are the same sensor???? I dont see two sensors at all just the abs sensor, which my abs light is off and no brake light

The airbag module is not connected, could that cause it??? Other than that, I have no idea. If something like trash or debry was in the way of the sensor wouldnt the ABS/brake light be on as well? Also I did get an alignment so alignment isnt the issue.

Its been on since the accident but figured it would go away once the alignment was done. Is there a seperate sensor/relay/fuse that may cause it???

Just to be clear, I had changed all my pads and swapped braked lines etc and then I filled the system with DOT 4 fluid. A week later the lights came on and it was my fluid that had "settled" or whatever and I needed more to make the lights go away..

Ill double check when I get home just at work at the present moment. But if anybody has a picture of the sensor that would helpful.

Also if the fluid was low wouldnt the brake light come on?

Strangely enough, no.... the VDC and Traction Slip lights come on.

Yes they are one and the same.

so if the abs light isnt on that means all the sensors are working. So unless the brake fluid is the issue "which ill check in about 2 hours" what else could it be? or is that it?

even if something was blocking the sensor's path, wouldnt the ABS light then come on? just curious.

If the sensors weren't getting readings then yes I would expect that the ABS computer would throw a code, disable itself and illuminate the ABS light on the dash.

There is only 2 things it can be at this point, the brake fluid level, and the stability control computer (under e-brake cover). There is an input shaft speed sensor on the transmission but AFAIK that is only used for S-mode engine RPM calculations. The A/T's have an output shaft speed sensor but pretty sure the M/T's don't have this.

Yea the brake fluid is not at Max or min.. Right in the half "cold temp". I didn't add any but would half way cause it to come on? I seriously doubt it but what do u guys think???

Is there a fuse or relay soley for it? Or anything on the rear end driveshaft, differential??

Just sounds like the vdc control module needs to be reset with Consult from the dealership. I happens here at work sometimes even when we only put in a new battery on some patherfinders & xterras

Half way down will make it come on but not right away, usually after the first acceleration or hill.

You can try manually resetting the VDC computer by disconnecting it and reconnecting. If that doesn't work you will need to visit a dealer.

fill the brake fluid to max, that could be the problem.

I will lol if I was right....

I basically added about 1-2 caps worth of brake fluid lol. Lights still on. Again no brake lights at all or abs light. The button still doesn't respond when I press it. Lights stay on regardless.

Sorry dude.... head to the dealer for the data codes....

Thanks I'll keep u guys updated. There any way to reset it manually? Just curious. Or just removing the neg terminal and putting it back?

no, its a ROM (Read Only Memory) type. The stuff that gets reset when you disconnect the battery is RAM (Random Access Memory) which is stuff like short term fuel trim, radio stations (on some vehicles) etc..

okay thanks.. Figured I would need to take it to the dealer but wanted to make sure. Thanks again for all your help guys. Ill keep ya updated in case this ever happens to another member.

Ever get figured this thing out? Sorry to bring this from the dead.

We have seen this issue crop up from time to time when there is a bad wheel bearing. It moves the speed sensor too far from the hub and it doesn't detect the hub properly.

Yep took it to dealership and they had to clear the code from the RAM of the ecu. Its happened to me on a dyno before but goes away but issue was resolved last year and havemt had issues since :)

Just today I was leaving a gas station, and when I went to pull I did a nice spirit from 1st to 3rd and the slip light blinked and then stayed on and then the vdc stayed on. Got to where I needed to go, I shut the car off and turned it on and If went away

Check your brake fluid level. If it's a little bit low. It will cause those lights to come on. :shakes head:

They rear brakes need to be changed. I ordered the pads and rotors already. I didn't realize it would cause the vdc to act funny

So I am having the same issue as you b1adesofcha0s, my skid light and VDC off light stayed on, after restarting the car, they turn off. Brake light isn't coming on at all though, just the traction lights. What's worrisome to me is that it happens after hitting a few skid patches on the highway (I'm currently in Germany where there's a lot of ice and slush on the roads at times). It'll usually happen when accelerating a bit hard, the lights will come on, I'll restart the car and all seems to be fine. Any idea what causes this? Is this just a pushing too much on the car thing and be nicer under nasty weather conditions? Or do I need to fork over way too much Euro to some German Nissan dealer to get it fixed?
