i am a mechanic at BMW. if you are refering to runflat warning systems the idea is that the wheel speed sensors, which also are integral for your ABS system, can detect change in tyre speed.
The reason that the wheel speed information can be taken as tyre pressure is because a fully pumped up tyre has a larger circumference that a flat one, therefore a pumped up tyre rotates slower than a flat.
The wheel speed sensors send info on all tyre speeds to the cars computer system which compares them. when they are out of a specified tollerence then the flat tyre warning light will be turned on. This only works for sudden or consistent loss of pressure and the warning usually isnt activated for slow pressure loss, which is normal across all tyres.

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.
How the ABS system senses a low tire pressure?
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.
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.
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.
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.
What is the pressure applied in ABS?
The pressure applied in ABS (anti-lock braking system) varies depending on the specific system and operation conditions. Generally, ABS modulates brake pressure to prevent wheel lock-up during emergency braking, which can range from a few hundred psi up to over a thousand psi. The system constantly adjusts pressure to maintain optimal traction and control.
