Passat (B6) :: 3.6 - EPC And Traction Control Lights Come On Once In A While
Jun 15, 2009
Recently I started to have my EPC and Traction Control Lights come on once in a while (no CEL). And when that happens, it looks like my Passat is going into limp mode, because it drives, but it hardly has any power.
VagCom confirmed that the problem was coming from Throttle Body (I don't remember the exact code), I replaced the throttle body, did Throttle Body Adaptation, but I still have the same problem.
Here is the most recent VagCom screenshot:

For the past week I have had the steering wheel and traction control warning lights come on after I start the car after sitting for a long period of time. Once I drive the car a few feet the warning lights disappear. The model is a 2007 2.0T with 72,000 miles. What are next steps or should I head to the dealership? I'm out of factory warranty but have a third party warranty that expires at 75,000 miles.

My '07 passat has recently been giving the same error sequence, I am driving and start to accelerate when a ding sounds and the traction control light on the right display lights up, as well as the EPC (or ECP) on the right display along with the ! on the MDF display which blocks the use of the cruise control.
Shortly after (30 sec.) I lose the turbo, and then the engine light comes on on the left display. The turbo resets after turning the car off, and the rest to the error lights reset in ~24 hrs.
It happens when I am driving on dry clean roads, so I have not been losing traction. Took it to the dealer and they said the battery was bad, replaced it under warranty and all seemed well, but 5 days later the problem re-occurred, everything reset, and then re-occurred again 2 days later.

I need to troubleshoot a problem with the ABS & Traction control lights on a 2006 Mountaineer Premium with 126,000 miles. During the year that I have owned the vehicle this problem has occurred every time it is driven on a long trip. The previous owner never drove on longer trips so has no experience with this problem.
When you drive the vehicle around town and on shorter trips (less than an hour) there are no indications of problems. The ABS and Traction control lights come on as part of the start-up check cycle and go off. The ABS and Traction control work in low traction conditions and the lights function correctly when either one is activated.
The unusual behavior occurs on trips longer than an hour. Typically after about 1 1/2 hours at highway speed both the ABS and Traction control lights come on as well as the Wrench symbol in the message panel. It you hit "Reset" the Wrench symbol goes away but the ABS and Traction control lights stay on. The brakes work normally. I do not know if the ABS and Traction Control will work. I have never been in a low traction condition when the lights are on.
Both lights stay on until you stop the vehicle and turn off the ignition. When you restart the vehicle the ABS light is on but not the Traction Control light. When you start to drive the vehicle the ABS light goes out immediately.
After about 1/2 hour of driving both lights come on and the Wrench symbol displays in the message panel. Whenever you stop the vehicle and restart during the trip the cycle repeats. The day after you finish the long trip everything is normal for driving around town and on short trips.

Evertime I turn left the brake light, traction control and stability control lights come on and the car starts dinging. Mechanic says it could be front wheel bearings because they are tied to the ABS system??? But I have been seeing alot about wheel speed sensors?
Second, everytime I brake suddenly, a cloud of smoke comes from the front end and there is a burning oil smell. The oil is fine and no leaks. Again mechanic says it could be a cracked CV boot throwing grease?
Lastly everytime I put in reverse or when I lightly put pressure on the brakes when driving I get this noise like a humming (errrrrrr) noise. Its not the grinding/squealing noise you would get when brake pads needs replaced. I only have 60k miles on this.

My college son's 2014 Charger V6 has developed three issues since he purchased it used in late May. The cruise control has stopped working and the anti lock brake and traction control lights are constantly on. Any possible cause?

From what I've read it seems this combo of lights usually stops the awd from working. However the lights came on and as a test I did a few hard 1-3 pulls listening for wheel spin... Nothing, all traction and pull.
What may be causing these lights? Hopefully I can get my vag com to work so I can scan it. Planning on checking the fuses and connections on the battery too.

I put in a new air filter today, 2003 GTI vr6 24v, and three lights (Check Engine Light, Electronic Control Power, and ABS) all turned on and haven't turned off yet, I'm not sure if I plugged in the sensor wrong or if there is something else that needs to be done. None of the lights were on before.

New problem this evening went to start Santa fe and ABS and Traction Control lights are on tried to shut ignition off and restart and both remain on. Drove the vehicle and noticed no brake control problems, tried to push the traction control switch and no on off control of light remains on. I believe in a situation such as this a good computer diagnose at the dealer is in order.

2010 Prius 98,000 miles - No Accidents
I was driving on the freeway cruising about 65-70mph.. Not using the brake at all. All the sudden the car starts beeping loudly with the Brake light going off, traction control light going off, and the ((!)) light as well. So I wanted to pull over to the side and realized my brakes were not working . It was the same as if you're trying to brake the car when the car is turned off. I slowly pulled off the freeway. Tried to reset the ECU, battery, everything, thinking at the traction control is just going crazy.

Within a few miles my ABS and traction control lights go on...when I shut it down they go back off, but, within 5 miles or so, they're back on again..how do I diagnose on which wheel the offending sensor is causing this?

My car sat for 2 days this week and was completely dead when I got back. I had the alternator and battery tested and they were both fine. I put everything back and ran a vag-com and it still shows running voltage at 9.7 volts. ABS and traction control lights are on intermittently. It seems to be having trouble starting which leads me to believe it's a bad starter but I don't know how that would drain my battery. The car also has a sunroof drain leak which got water on the monsoon amp. I've tried with and without the amp connected. No difference.

I had not driven the Prius in a few weeks, and even then, that was for less than five miles, and had the low tire pressure indicator come on late last week when the temperatures cooled down, which I fully expected given my opportunities with the Toyota Dealer properly inflating tires. We were away for another week and returned today and I decided to check the tires and add air, and in addition to the tire pressure indicator, the ABS, Traction Control, and Brake Indicator lights were on. As soon as I filled all the tires to the specified PSI, that indicator disappeared but the brake related ones all stayed on.

This morning after starting my accent the abs, e-brake, and traction lights all came on. What could this indicate, and should I not drive the car till it is fixed? I checked brake fluid levels for the of it, and they were fine.

So recently (yesterday and today) when driving I've noticed that my ABS and traction control lights come on along with the usual CEL for a bad 02 sensor, what could be causing these to come on, the part that throws me off is that it only happens when it is wet outside or if I run through a puddle...

A few days ago my wife's 07' explorer 4.0L, 4wd, 72k miles, had the abs light, traction control light, and a wrench light all come on. By the the time I got to look at it, they were off. Now 3 days later, they have all come back on. To me it seems like a electrical issue or maybe a sensor or something but I wanted to get your thoughts on where to start looking.

Just purchased a 2009 Matrix XRS Manual transmission with 67,000 miles on it. I can't get the VSC Off and Traction lights on the panel to go out.
During our test drive, I had turned the system on and off to make sure it was working, and didn't seem to have any trouble with it.
I went to have it inspected yesterday. During the test, they hook up to the ODBII port to check emissions. The tech had trouble getting it connected the first time, saying the connection was going in and out. Eventually, they were able to get it connected properly and passed the inspection.
After they pulled the car out of the bay, the VSC Off and Traction lights were solid on, and they have been every time I've started the car since. Checking the manual, all I should have to do to turn the system back on is press the traction button, but that doesn't seem to be working at all. I also tried holding it down for 30 seconds or so with no luck.
The lights aren't flashing, so I don't think this is an error, I'm wondering if the computer got confused somehow with the ODBII port issues.
Stuff I've tried:
1. Followed these instructions for the Highlander Hybrid thinking maybe Toyotas will generally do this. That just caused most of the lights to flash on the panel and didn't bring up any VSC diagnostic messages.
2. I pulled the panel from the dash out to check to make sure the button was working, and I do get connectivity between the two outside pins while the button is pushed in.
how to get this to reset, or what the problem might be?
