Car is sensing a problem with the stability control system (DSC) or the antilock brake system (ABS). usually an ABS problem will turn off the DSC, so DSC may be ok, just ABS needs a look at.

since its an '08 model, it should still be covered by the BMW warranty provided you live in the USA. take it in and have them fix it. not safe driving with both systems deactivated.

On my 91 cougar it sat for about 2 months due to a power steering problem I fixed that problem now my abs and brake lights stay on is it possible if I bleed all four brakes they might shut off?


"Is it possible if I bleed all four brakes they might shut off?"

If you bleed the brakes all you will do is remove any air in the brake lines and replace the brake fluid with new fluid. Do this in any event if the brake fluid is 2 yrs old or more.

This will have no affect on the ABS warning light and when the light is displayed the ABS has turned off because there is a problem with the ABS. You will not get it back on until the cause is determined and fixed which may be just a failed wheel speed sensor.

The brake warning has probably been triggered by the same failure that has caused the ABS warning light (since they came on together and bleeding the brakes should make no difference).

If the car sat for 2 months, no doubt the battery went flat. You have not mentioned anything about the battery but if your battery is in poor shape this can trigger warning lights in many cars especially the ABS (and stability control systems).

The best option is to have the vehicle scanned for fault codes that have been generated and there will be one or 2 if these warning lights are displayed. Scanning the ABS for codes will show up one or more issues and you can trace the problem from there. I think you will find the brake warning and ABS warning have been caused by the same fault.

In any event make sure you check the brake fluid level in the car and look for any external leaks of fluid that may have developed. Check the operation of your brakes to ensure they are working normally and that the brake pedal is not slowly dropping to the floor when you continue to apply pressure. Bleed the brakes if the brake fluid is 2 yrs old or more.

How can i reset esc and abs dash light


The warning lights will stay on until the problem with the stability control and anti lock braking system is addressed and rectified.

If the warning lights are still showing there is still a problem with the system such as faulty wheel sensors.

The Service stability light on 2003 escalade comes and shuts down my vehicle. What does this mean and what will it cost to fix


Cluster warning lights

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL, CEL and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

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.
4
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.

My ABS light is on and off on a 2006 Mercury Mariner. Do I need to do something to get this light to stay off


SECTION 206-09: Vehicle Dynamic Systems 2006 Escape/Mariner/Escape Hybrid/Mariner Hybrid Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 03/29/2005 Anti-Lock Control adobe.gif Printable View (63 KB) The ABS consists of the following components:
  • Hydraulic control unit (HCU)
  • Anti-lock brake control module
  • Front and rear wheel speed sensors
  • Front and rear wheel speed sensor rings
  • Stability control sensor cluster
  • Stability/traction control switch
The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the HCU modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
--------------------------------------------------------------------------------------------------------------------------------------
The ABS module is self monitoring. The module will carry out a preliminary electrical check of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 20 km/h (12 mph). The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a malfunction is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

You may need to have the dealer run a scan test to determine the DTC fault codes. Then go from there. Autozone can't read these codes as tehy are chassis codes. They only can read powertrain codes.

My brake light stays on in the dash


Typically, worn brake pads won't cause the warning light to come on. Some vehicles have a brake fluid sensor that can cause the light to come on. Also make sure the parking brake is completely releasing and if you have ABS, make sure everything is working there.
Uneven brake pressure will certainly cause the brake light to come on, that's when the master cylinder is working a lot harder for one circuit (front or back) than it is for the other, indicating either low brake fluid level or damaged/worn wheel cylinders.
If you can't find anything by examining the brakes, you may need to pay for a scan of the ABS computer.

ABS and ASC warning lights stay on 2000 530d


Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car
