The ABS moniters the wheel speed of each wheel. A soft tire will spin faster than the others. After a short time the system determines there is something wrong with that one wheel and turns the light on notifying the driver there is a problem.

How do you reset the computer on a 1997 buick park avenue after a battery failure The abs check tire pressure and traction lights are coming on for no reason?

The computer resets itself. as for the ABS-Traction control-Tire Pressure... the ABS sensors on the wheels get information for your ABS, traction control and your tire pressure monitoring system, if the ABS has a problem, it disables itself along with the traction control and the tire monitor. You have a problem with your ABS system..get it checked out


How does the braking system sense low tire pressure?

The ABS (antilock brake system) system monitors the rpm (revolutions per minute) of each wheel. A tire low on air pressure will consistently spin faster than the others. The ABS module with the information it receives from all the wheel speed sensors determines something is wrong and illuminates the check tire pressure light.


Will a tire worn down to the steel affect the ABS and Traction control system?

The tire will not affect the abs system but it will more than likely affect the traction control system. It could give a faulty read out due to the treadwear.


What does it mean when the abs trac and check tire pressure lights are on?

It probably means your tired pressure is low and your traction control is not working properly (or thinks it isnt) because of the low tire pressure.


How does going to a bigger tire size affect your abs brake system?

Yes. how?


What is the ABS on a 2001chevy pu?

The ABS system on a 2001 Chevy is to monitor the brake pedal pressure.


What does it mean when the brake abs light comes on your 2000 528i BMW and the tire gauge light comes on.?

The ABS light may indicate that the ABS system isn't working. The one in my van is coming on and going off from time to time. My mechanic says to wait until it is on all the time and he will replace the ABS module. The tire gauge light could mean that one or more of the tires have low pressure.


How does Tire pressure sensor work?

There are two general types of tire pressure systems, direct and indirect. An indirect system doesn't actually measure the tire pressure. It uses the wheel speed sensor (part of the ABS) to measure very minute differences in rotational speed between all four tires. When it senses a difference from what a nominally good tire is, it will turn on the tire pressure light. Note that you will need to check the tire pressure in all tires, as it doesn't indicate which tire is the problem. Once the tire pressure is adjusted, reset the light according to the owner's manual. You'll also need to do this after changing to a spare.Direct systems attach a pressure sensor/transmitter to the vehicle's wheel inside the tire's air chamber. This system uses a small battery-powered pressure sensor with radio transmitter on the back of each tire valve, attached to the wheel rim. Some direct systems use a sensor mounted to a metal band around the inside of the rim. The batteries are designed to last 10 years. There will be a corresponding radio receiver next to each wheel, which picks up the signal from the sensor and passes it to the system's in-car receiver and the information is displayed to the driver.


Why is your 1998 Ford Expedition skipping?

It would be either the ABS system isn't working properly or the tire's tread. If it's the ABS, you should have a ABS light on or at-least have trouble codes stored in the computer. A faulty caliper that is sticking can cause that tires brake to stay applied longer than the abs system wants.If the tire is abnormally worn(feathered or cupped) it will cause that tire to lose traction more easily. If the tread is low and the surface is wet the tire might be "hydroplaning", this is when the water under the tire patch, that the tire's tread can't move fasten, actually lifts that tire of the road.


How does anti-lock brakes work?

ABS senses when your tires have lost traction and induce a changing pressure on the brake pads, reducing the pressure to regain control, then reapplying however much pressure you are telling the system to apply through the brake pedal. This is the thumping you feel when the ABS activates. ABS is q safety feature that helps you stay in control of the vehicle because as you're tires lock up you lose steering controllability, especially on slick surfaces.


What is the difference between traction control and ABS?

Traction control seeks to reduce or eliminate tire slippage while accelerating. ABS (Antilock braking system) seeks to reduce or eliminate tire slippage while braking.


Lights on the dash nuff already how can you turn - disable - the lights on your dash tire pressure service engine soon abs trac engine security light. can these lights be disabled?

Are you saying that all these lights stay on after you start the car? If so, you need to get the problems fixed that are causing the lights to stay lit. You have these problems. ABS-Anti-Lock Brake System problem. Check Engine- Emissions Controls Problem Trac- Traction control turned off Tire Pressure-Low Tire Pressure Security-?? Read your owners manual carefully.
