Maybe the sensor came unplugged or got water in the connection if you remove the tire and remove the brakes and rotor there will be a gear attached to the sensor follow the wires to the connection and unplug it you can use alcohol to dry it out and vasilene to seal it so that water will not getr in it in the future they sould also have wire dryer at your local auto parts store and electrical silicone aswell but it can harden over time witch is why i like the vasilene

Abs light and esp light are on in my pegoet 308


If any of four abs sensors is not working then abs light comes up and subsequently affects car's stability (esp). OBD diagnostic scanner will find out that which sensor is causing it. If all sensors are fine then most probably there is a problem with your abs/esp unit in engine bay.
PEUGEOT announced a problem with the 308 vehicles and it has been identified that the operation of the ABS/ESP braking unit may be affected by the ingress of water. Previously, recall are announced to be affected vehicles to reinforce the resistance of the ABS/ESP unit to water.

I have abs and brake light warning lights on, however, when checked by mechanic the abs brakes are working fine. whats causing light to come on?


FOR ONE THING CHANGE MECHANICS ! HE SHOULD HAVE FIXED THE PROBLEM, YOU MAY HAVE A SERIOUS BRAKE ISSUE ! IF LIGHT IS ON IT WILL NOT PASS INSPECTION ! YOU MAY HAVE AIR IN SYSTEM, NEEDS BLEED ! FLUID COULD BE CONTAMINATED , NEEDS BLEED OUT, REPLACED W/ FRESH FLUID ! ABS REQUIRES THAT THE REAR BRAKE CIRCUIT OPERATES BEFORE THE FRONT BRAKES, THIS PREVENTS SKIDDING, THE PURPOSE OF ABS BRAKES, CORRECT ? MASTER CYLINDER HAS SEALS, CONTAMINATED FLUID AFFECTS SEALS, BRAKE LIGHT WILL STAY ON UNTIL PROBLEM IS RESOLVED !!! REAR BRAKES IF SHOES NEED ADJUSTED, CLOSER TO DRUM ! THIS WILL HELP, BUT BLEEDING OUT ALL BAD FLUID & AIR IN SYSTEM IS PARAMOUNT !!!!!! BRAKE LIGHT SWITCH MAY NEED REPLACED, PROPORTIONING VALVE WHICH SEPARATES FRONT FROM REAR BRAKES , IS OUT OF BALANCE, THE VALVE NEEDS TO BE @ A NEUTRAL OR CENTERED POSITION, COULD BE STUCK TOWARD EITHER BRAKE CIRCUIT, MORE FRONT THAN REAR, UNDERSTAND ? THINK I COVERED YOUR ISSUE, PLEASE RATE MAY ANSWER ! THANKYOU,

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.

Abs light is on . brakes work just fine and the fluid is full


Hello, lets test that BMW M5 ABS braking system, OK. First, drive down a street with no traffic. Speed up to 30 to 40 MPH. Then slam on your brakes hard, if the brake petal is pulsating and there a noise like clunk,clunk,clunk,clunk noise. Your BMW ABS is working. If not, then the BMW ABS isn't working.


ABS system and what it does to your BMW. All it amount to is it doesn't lock up the braking system. It just applied the brake and release in micro seconds. This keep the vehicle from sliding side ways on wet roads, snowy roads, icy roads or even on dry roads. In other words, it keeps the front of the BMW in a straight line.



If your BMW ABS isn't do this, you'll need to have the ABS braking system serviced. GB...stewbison

My abs warrning light is showing on my bmw 316 and does not go out..


On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system.

What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on. This should have no effect on normal braking. Even so, ABS will NOT be available in an emergency situation or when braking on a wet or slick surface.

CAUTION: If the brake warning light also comes on and remains on while the ABS warning light it on, it signals a serious problem. Your vehicle may not be safe to drive. The brakes and ABS system should be inspected immediately to determine the nature of the problem!

If the ABS light comes on momentarily then goes out, the nature of the problem is usually minor and the ABS system usually remains fully operational. Some vehicle manufacturers call this kind of fault a "nonlatching" fault (meaning it isn't serious enough to disable the ABS system).

Regardless of the type of fault that occurred to trigger the ABS warning lamp, a special "code" is recorded in the ABS module's memory to aid in diagnosing the problem. On some vehicles this code can be retrieved by putting the ABS system into a special diagnostic mode. The code is then flashed out through the ABS warning lamp. The code number refers to a diagnostic chart in a service manual that must be followed to pinpoint the faulty component. On other applications, a special "scan tool" must be plugged into the vehicle's diagnostic connector to read out the fault code.

Problem with my cruise control and ABS light on 03 Explorer


Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
  • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    -----------------------------------------
    Please report back, I am curious if that is what it is. Good luck
