Brake warning light isuzu npr 300

Main brake warning light, abs light and asr light come on either immediately on starting or up to 1/2 hr later. Started happening after 120000km service which included wheel bearing repack. Brake fluid level ok, truck drives normally. I assume abs and asr wont work. Can you help please?

SOURCE: brake and ABS warning lights on, trac off on.

You may have a bad abs controller. You need to get the code for the abs light from a shop or auto parts store.

There is probably a problem with you anti lock brake system. Have it checked at your local dealership. Brakes are a problem that should never be let go.

SOURCE: brake lights stay on all of the time, ABS light on when driving

You most likely need to replace your brake switch, which is a
a $8 part. If you look up along the brake peddle you will see it depressing a switch. on the end of that switch is a electrical connector that you can press on one side to remove.
Once removed your brake lights will be disconected and your ABS
light should go off. You then need to replace the switch that it pluged in to.

SOURCE: 2005 toyota prius abs brake not working warning

Hmm, I'm not sure what a main chip is but, there is a few reasons for this problem.

  1. ABS Sensors - there could be something wrong with a sensor and/or the wiring to them
  2. The wheel bearing speed sensor in a wheel is bad or intermittent which then tells the computer that wheel is traveling at a faster or slower rate of speed then the rest which in then the computer turns the abs light on.
Now when your warning lights go on, the computer sets a DTC code which is the key to helping solve this problem. If you can get the DTC (Data Trouble Code) from the dealership or from someone who can scan your can, I can better assist you in figuring out what's wrong. Hope this helps.

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,

Gear shift stays in park and abs esp and asr lights on


1) try to use the self diagnose.
2) place ignition swtuch in the start position, the lights coming on
3) engine starts, the brake light sould turn off inmediately. the ABS ligth will illuminate for aprox 6 seconds.
4) test drive the vehicle at speed above 20mph for a few minutes. during the test the both test lights should remain off, if any one of the warninign light utron, take note of the condition.
5) stop the vechicle using the braking pressure.both light should remain offf during the stopping procedure.
60 place the gear selector in to PARK, and observe the warning lights, they should both be off.
God bless you

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.

I have a 2002 VW New Beetle. The ABS light has come on and there is a chiming beep and the ABS light flickers. What could be the problem?


ABS - Anti-lock Brake System.
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.
tdisline_703.jpg


ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. ESP system includes the ABS system.

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.
