you need someone to scan it for codes but it sounds like the speed sensor for one of the wheels is droping the signal to the abs unit at lower speeds they can see that with the data stream with a scanner

SOURCE: Anti-lock brakes come on just before I stop when payment is dry

I have a 1997 chevy k2500 and had the same problem. My fix was where the abs sensor goes into the housing. There was a little bit of rust that pushed the sensor away from the housing just a little which caused a false reading. I removed the sensor and used a roloc disc to polish the metal and reinserted the sensor. I have had no problems since.

My 2007 Jeep Liberty has started to "shimmy" when I put in in reverse and when I'm pulling into a parking space. I have it in 2wh drive but it feels like it's in 4wh. Any advice?


are you using 4wd /yes /no
are you on ice, or off road?
or just pavement ice free,
we cant guess that. and is KEY
car comes new with 3 different 4wd systems
first 2 are part time
and last full time 4wd and 4lo (PT)
all three stay out of
part time on icefree pavement
4lo is part time too, and same rules its for offroad only.
sure
the cluster has 3 lamps
fulltime
part time
and
4 LO
tell me, does or has fulltime ever come on in 4wd
if yes,its AWD jeep.
if not the car is part time, in 4wd
and is only for iced roads or offroad.

5min work look at rear of transfer case
bingo, now you know what you got

Anti-lock function on brakes is triggered by applying brakes while steering wheel is turned hard over


Sounds like you are losing wheel speed signal when under hard turns. This is commonly caused by the harness at or near the wheel speed sensor has a bad connection of there may be a break in the wiring that intermittently loses signal to the ABS module and causes the anti-lock function to happen, (loss of wheel speed is like wheel skid as far as the ABS module is concerned) It is usually necessary to have a scan tool to monitor the data and read codes on the ABS system. You may have to take vehicle to shop that is capable of diagnosing the problem.

I have a 5 speed 1994 toyota landcruiser prado short wheel base. The electric switch for the hubs illuminates when engaged however the 4wd light will not illuminate when the switch is engaged,...


what series? 80? LC?
which car do you have, we dont know see this quote
All 80s sold in North America and Europe now have a full-time four-wheel drive system. In Japan, Africa, and Australia, a part-time system was still available. 80s produced between 1990 and 1991 had an open centre differential which was lockable in 4HI and automatically locked in 4LO. From 1992 onward, vehicles with anti-lock brakes had a viscous coupling that sent a maximum of 30% torque to the non-slipping axle. The differential was lockable in 4HI and automatically locked in 4LO. unquote..
what drive do you have.????????? see the ambiguity here>>>????
Part time or Full time, it varies by unsaid COUNTRY !!

do not run Part time on dry pavement only ice or offroad.
or it will not shift or if does , it will wind up.

with or with out center differential.????
if with center and on dry road, the switch is bad or the linkage is failing
if no center diff, stop driving in part time 4wd on dry roads.

check the rotors for scoring,worn rotors will "feel"like the abs is coming on due to the vibration caused.and will account for the extended stopping distance.

I expereince what sounds like the abs engaging when I turn


a bad wheel speed sensor will do that generally in the wheel bearing on newer models but not always if the sensor is external rust can build up pushing the sensor away bottom line the abs sees the difference in speed and assumes the vehicle is skidding or slideing and deploys generally only happens at low speed 7-10mph when stopping hope this helps

2001 Chevy Silverado anti-lock brakes activate on dry pavement, the pedal pulsates, the typical anti-lock brake sound is heard, and the truck feels like it is not going to stop at times


One of the sensors has gone bad and needs to be replaced, the other thing to that would also do that is the ABS sensor is dirty or needs to be re gaped to the speed ring on the hub. There was a issue bulletin with your Tahoe on the ABS activating under 8 km/h. Good luck and hope this helps, if not clean out the sensor with brake parts cleaner and check the wire harness and ABS sensor bracket. Re gap the sensor to the speed ring hub. Here is the bulletin.

Anti-lock brakes activate on dry pavement


First, is the ABS light on? Does it come on when it's doing it? Make sure the brake fluid is full, and the brakes are still servicable, ie, pads still have meat on them. If so, the abs control module or a speed sensor might be on the way out. This is a safety issue, and I would recommend getting the truck to a good mechanic to have it checked out.

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

    Antilock brake system engages on low speed stops on dry pavement on my 2004 Silverado.


    The most likely cause is rust buildup under wheel speed sensors causing them to dislodge(lift up) from front hubs and read incorrectly. If recall has been performed to fix this problem...You may have to replace the appropriate hub in order to stop the ABS activation at low speeds. Let me know if i can help more.

    TRACTION CONTROL.


    that is what it is desgined to do - reduce acceleration and apply the brakes intermittently when the wheels spin. You have a switch you cn push to disable it. You need to disable each time you start car. See owner manual.

    06-10: Traction Control 1996 Contour, Mystique Workshop Manual
    DESCRIPTION AND OPERATION Traction Control System The optional traction control system is designed to control wheel spin when accelerating on slippery or loose surfaces. Traction control system is available only with anti-lock brakes. The traction control system includes the following components:
    • Hydraulic control unit.
    • Throttle control actuator (9N825).
    • Traction control switch.
    • Traction control warning indicator.
    • Front brake anti-lock sensor (2C204).
    • Rear brake anti-lock sensor (2C190).
    The traction control system operates as follows:
    • System functions by transferring torque from the spinning wheel to the wheel with the most traction.
    • This is achieved by applying the brake at the spinning wheel through the hydraulic control unit or reducing the throttle opening.
    • Traction control braking and throttle control occur at vehicle speeds up to 50 km/h (30 mph).
    • At vehicle speeds above 50 km/h (30 mph), only throttle limiting control is used.
    • If speed control is operating when traction control system engages the traction control system will disengage speed control through the use of a speed control relay. This action is the same as applying the brake pedal with speed control engaged.
    1996 contour
    Traction Control Switch The traction control switch is located on the instrument panel, left of the steering column.
