My 2001 Ford Windstar brakes locked up driving down the road the other day. The brake pedal was just floppy and only engaged when it was near the floor. I was close so drove it on in and by the time I


t sounds like a battery problem ,, and or possibly a problem with the rectifier circuit.l That is what converts the AV current from the alternator to DC. if its pushing AC power the battery wont charge and you will have these issues with electrical malfunction.. you will also need to check your ACC fuse for the player and TV that inst working.

Anti-lock system light on


Anti-Lock Braking System (ABS)
Purpose Anti-lock brake systems (ABS) - generally also referred to as anti-lock
systems (ALS) - are designed to prevent the vehicle wheels from locking
as a result of the service brake being applied with too much force, especially
on slippery road surfaces.
The idea is to maintain cornering forces on braked wheels to ensure that
the vehicle or vehicle combination retains its driving stability and manoeuvrability
as far as physically possible. The available power transmission
or grip between tyres and carriageway should also be utilised as
far as possible to minimise the braking distance and maximise vehicle
deceleration.
Why ABS? Although today commercial vehicle brakes are designed to a very high
technical standard, braking on slippery roads often results in potentially
dangerous situations. During full or even partial braking on a slippery
road it may no longer be possible to fully transfer the braking force onto
the road due to the low coefficient of friction (friction coefficient (k)) between
the tyres and the carriageway. The braking force is excessive and
the wheels lock up. Locked wheels no longer provide any grip on the
road and are almost incapable of transferring any cornering forces
(steering and tracking forces). This often has dangerous consequences:
- The vehicle becomes unsteerable
- The vehicle breaks away in spite of countersteering, and starts to
swerve.
- The braking distance is significantly increased
- Tractor-trailer combinations or semitrailer trains may break away or
jackknife.
Load sensing valve influence On dry roads today's load sensing valves (ALB) alone are often capable
of preventing the wheels from locking if the vehicle is unladen; they also
help the driver to effectively grade the braking process on wet road surfaces,
but they are unable to prevent locking as such (no slip monitoring).
In addition, they are unable to counteract any overreactions on the
part of the driver, or any variances in frictional or adhesion coefficients
which may apply to different sides of the vehicle, or indeed to its different
axles (?-split road surfaces).
Benefits of ABS: Only the Anti-Lock Brake System (ABS)
- guarantees stable braking characteristics on all road surfaces.
- maintains steerability and generally reduces the braking distance
- prevents vehicle combinations from jackknifing
- reduces tyre wear.
Limits of ABS Although ABS is an effective safety device, it can not suspend the limits
defined by driving physics. Even a vehicle fitted with ABS will become
uncontrollable if driven too fast around a corner.
So ABS is not a licence for a maladjusted style of driving or failure to observe
the correct safety distance.

ABS Training Anti-Slip Regulation (ASR)
Anti-Slip Regulation (ASR)
Why ASR? Increasing the engine output (accelerating) on a slippery road surface
can easily lead to the maximum adhesion on one or all powered wheels
being exceeded causing them to spin, especially if the vehicle is unladen
or partially laden.
Spinning wheels when driving off or accelerating represent a safety risk
just like locked wheel do when braking.
Reasons - Wheels that spin transfer just as little cornering force as locked
wheels.
- They also no longer transfer any tractive power onto the road.
Consequences - Vehicles that do not move or get stuck.
- Vehicles that can no longer be steered, jackknife on uphill uphill
gradients, or swerve in corners.
Benefits of ASR ASR prevents the powered wheel from spinning and provides the following
benefits:
- Tractive power and cornering forces are maintained.
- Stable driving behaviour is ensured when moving off, accelerating
and negotiating corners on slippery roads.
- The indicator lamp (if installed) is used to warn the driver of slippery
road conditions.
- Tyre wear is reduced to a minimum, and the motor vehicle's drive
train protected
- The risk of accidents is further reduced.
ASR and ABS: ASR represents a worthwhile addition to an ABS-controlled braking system.
All that is required to turn ABS control into full ABS/ASR control is
an ECU with the additional ASR function and a few additional components
for controlling the differential brake and the engine. This why ASR
is only available in combination with ABS.
Even a differential lock for off-road use and ASR do not exclude but complement
each other.
Limits of ASR The traction capacity of an all-wheel driven commercial vehicle can not
be achieved by a motor vehicle with only one driving axle - not even with
optimal ASR.

Have a 2001 pontiac sunfire can be driving down the road trac off light will come on and car will start running rough then die turn car off then back on push ets button then light goes out pull up on...


You have an ABS Braking System Malfunction

Just sillly for a professional to say there is nothing
wrong

Your car is not safe to use at all

Need a different repair shop & make sure they
underdstand all the details of the issue & they
write down what you tell them

I never recommend a dealer, but in your area that
may be an option. Don't take it back until they drive
100 miles with no issues

It is a sign that you either have a bad wheel bearing or 1 off your speed censors on 1 of the tires is bad, I just had this problem with my olds alero, but it was a wheel bearing that needed replaced.

2003 Bonneville SSEI


I am having the same problem and also occasionally the cruise just shuts off when I am driving on dry, straight roads. Code C1288 was cleared, but it continues to happen. I was told that the electric brake module needs to be reprogrammed and that it will cost about $80.00. They are still looking into it.

Good Morning. My ABS light comes on intermittently in my 2001 Nissan Xterra SE model. The light will stay on until I turn the car off, but when I start it back up later the light is off. For the light...


a lot of times the sensors on each wheel become covered with brake dust if you remove the wheels and clean the sensor with brake cleaner this will solve the problem but keep in mind it may happen again when the brake dust gets on the sensor again
