Get the code reader with ABS reading so you will know what side has the problem. I know is the wire going to the front hub sensor is the one alweys go.

SOURCE: Impala - trac off and ABS light along with service traction syst

THE PROBLEM IS WITH A HUB WHEEL SPEED SENSOR OR MORE LIKELY THE HARNESS LEADING TO THE HUB.

CHECK THE RESISTANCE AT THE HUB CONNECTION, IT SHOULD BE BETWEEN 900OHMS AND 1300OHMS. THEN SWITCH TO A-C VOLTAGE, IT SHOULD BE 100MV WHEN TURNING THE WHEEL BY HAND. IF BOTH CHECK OUT THE PROBLEM IS IN THE WIRING TO THE HUB.

THE RIGHT FRONT HUB USUALLY HAS A BEND, DOWNWARD THEN UPWARD NEAR THE CONNECTOR TO THE HUB. THAT IS WHERE THE PROBLEM USUALLY OCCURS.

NEW HARNESS WIRES CAN BE BOUGHT AT THE DEALER.

SOURCE: Enhanced Traction System Warning Light (TRAC OFF)

Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.

SOURCE: 2003 Chevy Impala Service Traction Sytem show on Dash

I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.

SOURCE: 2006 Chevy HHR Traction Control Light and Check engine

i fixed mine by pulling each and every fuse in all the fuse boxes and replacing them with new ones. the hhr fuses have a tendency to work loose and cause all kinds of little problems. i searched the forums for the answer to the traction control light problem and never found an answer that worked until i talked to a "shade tree" mechanic in my area and he told me to do the fuse thing. been a month now and no more problems.

Posted on Jul 14, 2009

Testimonial: "The comments I left are the solution. The fuse thing does not do anything. It's a red herring. I replaced only the one that's associated with P0010 and It's been months."

Service engine, antilock brake, and trac off sensors are lit in 98 Olds Intrigue


Yes it is possible that you have a bad wheel bearing which has the abs sensor in it. Hence the abs light on. Traction control utilizes the abs as inputs therefore traction control will come on.

The ABS lite, No Trac Lite and Service engine lite keep coming on


When the Service engine soon, ABS and TRAC lights are turned on at the same time the computer control units for the engine and the ABS/TRAC systems has sensed a fault in the electronic controls of the engine and/or the emission system and the ABS and Traction Control system (part of the ABS system). When this happens you will seldom feel the car engine run any different or the car drive any different. There are about 200 possible faults that turn the Check Engine light on, the fault in your car is likely a part called the VSS sensor to know for sure what the problem is you must have the system tested; Kragen and Autozone parts stores do this testing for free

While driving slowly downhill in the snow I started to stop and my abs, trac, and service lights came on. They were off the next time I started my car but come on after driving a few miles every time I use...


You may have ice build-up in the brakes casusing the ABS to engage- [ the traction and service light will both come on with the ABS. Check to see if you have ice.

The abs/vsc/trac and check engine lights stay on. could this be a problem associated with emission control?


Its possible.

Whenever the check engine light comes on the VSC and Traction control will disable because they need the engine at 100% in order to function correctly. Since the ABS light is on I would have to wonder if it isn't an abs problem. Since the VSC and Traction control use the ABS sensors/system to function.

Or there is a problem with both the engine and the ABS.

The only way to know for sure is to have the PCM scanned and the ABS module to see what is goind on.

There's a little light that says "low trac" that goes on when i turn on my 1998 chevy cavalier.... what does it mean??


means the traction control module is bad. That light is suppose to come on when you lose traction to let you know the traction control is kicking in.

Replaced bank 1 sensor 1 O2 sensor with an OE


Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.

Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.
