SOURCE: 2002 Buick Century anti-lock brake problems

i recently had this problem too, except i had all the lights on (ABS, service vehicle, trac-off, AND service engine) they are all easy to fix without spending more than 20-30$ for labour (depending how much your mechanic charges you) mine did it for free and he found out why the engine light is on afterwards too. so to fix all these lights (abs, trac-off, and service vehicle you MUST get another ABS cable (i went to a garage, they were towing a GM vehicle to the junk yard so i grabbed some scissors and cut BOTH abs cables on each side (good thing i did because one was bad) and braught them to my mechanic. the reason the lights come on is probably a defect or in my case my mechanic said it was salt buildup in the wires (on the drivers side) so he cut the wire off and rewired the new one and BOOM all the lights came off (service vehicle, abs, and trac-off) now for my service engine it says catalytic converter but im trying to put some fuel system cleaner to help it out i read somewhere that this is a defect of the car, so if you dont have that light yet, SELL your car ASAP for as much as you can get for it (after fixing the lights of course) and always google (car name+recalls) in the search bar to see what youre getting into, take care

have you had this car scanned for codes? wheel bearing problems are problem, but get it scanned rather than throwing parts in it so many possibilities.

SOURCE: anti lock and service engine soon lights stay on after brake job

First of all your brake pads on this type of car do not have any kind of elec. sensor's, brake pads have tab's that will rub on your brake rotor's when brake pads are worn and make a ugly squeek sound to let you know you need brake's. I don't know if you all did the work or if a repair shop did, if a repair shop did the work a good tech would have seen both light's on and would have recommended computer diag. the reason the anti-lock light is on is your ABS computer pick up a bad signal from one of your sensor's, possible a wheel speed sensor, and same thing with your engine light computer got bad signal from one of your engine sensor's, one thing you could do is take it in and have computer diag. done and paid for that service or you could take it to almost any auto parts or some one like autozone and they will do a free computer code reading, but don't buy anything, then get back with us here at FixYa with rhe code number's so we can help you with your trouble code's.

My 2005 Chrysler Sebring started and turned off three times now, it just has a blinking red light?


Anti-Lock Warning Light (ABS) - If Equipped This light monitors the Anti-Lock Brake System (ABS) described elsewhere in this manual. This light will come on when the ignition key is turned to the ON position and may stay on for as long as four seconds. If the ABS light remains on or comes on during driving, it indicates that the Anti-Lock portion of the brake system is not functioning and that service is required, however, the conventional brake system will continue to operate normally provided that the BRAKE warning light is not on. If the ABS light is on, the brake system should be serviced as soon as possible to restore the benefit of Anti-Lock Brakes. 24 7 Locksmith Orchard Park NY 716 710 7400 Locksmith Orchard Park NY

How come the abs indication is on? what tire pressure should i put?


First - ABS is your anti locking brakes - light on means a sensor has triggered indicating there is a fault with your anti lock brakes. RE: Tire pressures - they're listed on a label on your drivers door.

2004 IMPALA ABS LIGHT AND SERVICE LIGHT ON


Hello tucky56, The ABS light stands for, " Anti-lock brake system ", it is a saftey feature designed to try and prevent cars from skidding when a driver panics and slams on the brakes. Although your normal brakes should still work, ( as long as your brake warning light isn't on ), the manufacturer recommends you take the car in to an authorized dealer and have it checked right away.
The service light being on is a reminder that it's time for your vehicle to have scheduled maintenance performed.
It is important that you take your vehicle to your machanic, or an authorized Chevrolet dealer as soon as you can for both of these issues.
It was my goal to provide you with timely, and accurate information.

You need to have the abs system scanned for codes. You likely have a bad wheel speed sensor on one of wheels.

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.

There could be a hundred causes for a check engine light. First step is to hook up a computer scan tool and see what codes the computer has. The next step depends on the codes.

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
