What is a vdc light


Vehicle Dynamic Control, measures inputs from different sensors ie: wheel speed from ABS wheel sensors, trans gear position & speed, Yaw rate, throttle position, etc then makes determination on how to best control veh in a certain situation (accelerating to hard through a turn, wheel spin on wet pavement, sliding during hard stops and such). Can do one or a combination of commands to recover an out of control veh like release brake psi to locked wheel (ABS), limit accelerator, down shift trans, even transfer shift power from side to side/frt to back on some models.

Slow/hard acceleration


I doubt either problem would cause the issue. The sensor would turn the abs light on, but that disables the abs brakes. The axle either works or it doesn't.

Speed Sensor (ABS Sensor) on my 02 Camaro (Passenger side rear) is shaved down. ABS thumps while driving and making right turns.


Most likely you have a defective ABS sensor which is part off the front bearing assembly. you will need have or if you have a code reader capable of reading abs codes find the wheel that is causing the code. Then source the part and if you have the ability to replace it replace it. The code/ light should go out when the abs signal is getting correct information.

Abs light comes when I accelarate to make a right or left turn from a side street or if I accelerate hard from a dead stop


First get the code that set the MIL Lamp. Will most likely, point to ABS Wheel Speed Sensor or System.
Then have the system diagnosed and repaired

2002 F250 4x2 SC - abs light comes on momentarily under hard acceleration, speedometer drops down at same time then pegs back up to normal speed. Coincides with tranny downshift. No loss of power, no wheel...


I bet you also lose the function of your cruise control when it happens. I would start first with checking the wiring connection on the vehicle speed sensor (also acts as abs sensor). Remove the sensor, clean it up and reinstall. If that doesn't work, replace the VSS.

You will find it on the top of your rear differential.

Side note: If you ever get stuck in the mud/snow and have to rock the truck forward/reverse, sometimes that will trigger your ABS light as well. This will normally reset itself after a few on/off cycles of the engine.

Grinding noise in front end and abs light came on


check wheel bearing play. if the play is excessive it will cause the abs sensor to come away from tone ring loosing signal, illuminating abs light.

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
