Question about 2003 Chevrolet Impala

2 Answers

How do I get my traction off light and ABS light to go off?

I was driving down the road and my charge light came. I kept driving then my air conditioner started blowing out warm air and all of my warning lights came on then my car decreased in speed. I pulled over to a gas pump and put the car in park and turned the switch off. Then I turned the switch back on and everything came on but my car wouldn't crank. The mechanic said it was my alternator. I bought a new one, he put it on. The car work good but those two lights will not go off.

Try disconnecting the negative cable on the battery. Wait at least 5 minutes and recconnect it. I can't say this will work. But on some of the cars I've worked on, the electronic modules (lamp drivers) that control these lights need to power down for a few minutes to reset. If the mechanic that installed the alternator didn't disconnect the battery this may be the fix. Maybe, not sure, but worth a try.

When certain systems (anti-lock brakes, traction control or air bag) detect a problem (like low system voltage due to a bad alternator) the computer sets a fault code and turns on the light. The light often will not go out until the fault code is cleared from the computer's memory.
Try disconnecting the negative terminal from the battery for 1 minute and then re-installing it. This will erase the computer's memory and erase the fault codes set when the alternator failed. If the two lights come back on, that means that there is a problem in the systems (they are inter-connected). Check all the fuses to make sure that a fuse which might supply power to these two systems did not blow out when the alternator failed. Replace any bad fuses. If the lights still stay on, you will need to take it to a mechanic for diagnosis and repair.

SOURCE: Traction Warning Light & ABS light on.

one of your wheel sensors are bad. if you go to napa they will let you use a code reader for free and that will tell you which wheel it is and you can replace that sensor. they are kinda expensive @ around 100 bucks a piece.

SOURCE: after replacing the left front wheel bearing on a 2003 ford focus, the abs and traction warning light stay on

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

SOURCE: I get intermittent ABS, traction control and power

The problem lies in one of the ABS wheel sensors. Most likely on the drive axle. Because the ABS sensor is only working part of the time. When it stops working it gives a signal telling the system that the wheel is spinning without traction. In doing this the vehicle computer tells the engine to go into the limp mode. If this is the trouble you may be able to confirm it by removing your foot from the accelerator and reapplying. It should regain power for the few fractions of a second it takes for the ABS sensor to retransmit the failure signal.

Abs light came on

What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:
  • ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
  • Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

My 2004 Pontiac grand am by ram air has trac off light on and the abs light on what does that mean?

It means that there is a problem with the ABS (anti lock braking system) and traction control systems normally because of a component failure. When you get these warnings the ABS and traction control systems will be de-activated by the computer.
So you will have normal braking function but no anti lock function on your brakes to prevent wheel lock up under hard braking and no traction control system to assist you when a tire or tires begin to lose grip on the road surface.

You need to have the ABS system scanned for fault codes which will help identify which component has caused the problem with the system. Frequently the cause is a failed wheel speed sensor or sensors which are needed for both the ABS and TC systems to operate and it is possibly that issue in your case also. Or there could be an issue with the wiring but there are numerous possible causes. You won't know until the diagnostics are carried out properly. For this issue I would take the car to a GM dealer service center. They have the correct scan tools to diagnose ABS and TC problems and will have seen many others with the same fault appearing.

In the mean time your car is perfectly safe to drive but bear in mind that you will not have the ABS and TC systems to help you if you drive too hard for road and traffic conditions and get yourself into trouble.

When i turn off the a/c the light went off. on down the road the batt light came back on and the time i got home the abs light came on what's the problem?

Sounds like you have the onset of a charging problem. Check the operation of you're alternator, or possibly an internal short in the battery.

All are tied into the ABS system, traction as well as stabilization, This needs to be looked at by someone who can hook up a diagnostic tester to read the fault codes stored in the ABS system then perform the correct diagnostic procedures to isolate the problem

Anti-Lock brake light and traction off light came on

U have most likely damaged a wheel sensor ring, in order to ID the one you damaged u will need to have the ABS/TRACTION CONTROL system tested for trouble codes, this will lead to the right area for repair.
