Not sure if you've solved your problem but I do have the answer. Also you failed to state that your vehicle will not go into drive because of this warning, which is generally the situation. When the drain ports under the hood clog, moisture runs down under the rug on the interior causing the wiring harness connectors on both sides of your vehicle to corrode. You need to remove the kick plates that cover the rug. Pry the rug away to expose a plastic shroud that covers the harness, just in front of each front seat on the floor. At this time you'll probably notice how wet the rug and it's foam backing is. Dry this out with towels and a hair dryer. Remove the harness cover. You'll see a clear plastic cover and a harness which looks like it's covered in electrical tape. Unwind the tape. This will expose the harness and connectors. If I can remember correctly, there is three connectors on each side, driver's and passenger's. See how corroded they are. Some maybe broken off. Cut back and clean these wires. Before connecting them, use a fine sand paper to clean the wires. Make sure these connectors are facing up and now cover them better than Porsche did. I used electrical tape and plastic wrap, followed by black plastic pull ties. The drain hoses, terminate under the vehicle, just in front of both doors. You'll also need to remove the plastic covers under the hood on both sides of the engine compartment beside the wipers. This will expose the firewall where the drains are generally full of debris like small sticks and rotting leaves. You'll save at least $2000 doing this yourself. Not knowing how to do this, it took me approx. 3 hrs. to do the job correctly. Good luck.

Sounds like it can be just a bad bulb but it doesn't have to be. If the car has ever been wreaked then it's possible that the wiring has been pinched somewhere near the headlight. The dimmer switch is in the steering collum and it would be effected buy turning but it's more likly to be efferted buy both lights not one There's a fuse panel near the drivers left kick panel that has the headlight fuses in it and it's possible the fuse is'nt making a good connection. With the lights on and the czr not moving you may just have to pull on the wires move the fuses and turn the steering wheell to find where the problem is. The dimmer switch should effect both lights.

If all these lights are on, one common issue for these cars is the ignition switch. Not hard to do. Wiggle the key and see if the lights will flicker or go off. Let me know.

I have a VW touran diesel 1.9. Recently there was a brake pad warning light indicated on my dash board, so I took it to my closest gargae to check. They replaced two new brake discs and the brake pads....


nope,it has to go back to a dealer(the computer is too expensive for a diy mech)they will reset it IF GENUINE parts have been used, as sensors are inbuilt into the pads.

I have this < !> lamp lit on my dash


It means a warning has been activated and is still current. When you initially start the engine you should see on the main screen in front of you what the warning relates to. Often for me it's low fuel!!! But at the moment it's also telling me to "Check Brake Lights". You'll need to go to your service place to get them to fix the problem and then the warning will be deactivated. The warning explanation doesn't stay on the whole time you are driving so you need to see it at the moment you turn on your car.

There is a light on my dash it is a ! with a bunch of lines all around it. what is that light for?


According to the 2003 Ford TaurusOwners Manual:

"Brake system warning light: To confirm the brake system warning light is functional, it will
momentarily illuminate when the ignition is turned to the ON position when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON position. If the brake system warning light does not illuminate at this
time, seek service immediately from your dealership. Illumination after releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your servicing dealership."

In short, as your brake linings (pads and shoes) wear out, the brake fluid level in the reservoir goes down.

You're probably right at the point where the level gets low enough to turn on the warning only under specific circumstances (cornering? hard braking?).

You can top off the fluid for the short term, but you should have your brakes inspected fairly soon.

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

    If someone took the time to look at the electrical schematic you will see several grounds in the circuit My first place I would go would be to check all the Grounds and Connections for the Brake Fluid level control, Brake Warning Indicator
    The Instrument Panel Cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs:
    • The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.
    • The electronic brake control module (EBCM) detects a low brake fluid condition. The IPC receives a class 2 message from the EBCM requesting illumination.
    • The electronic brake control module (EBCM) detects a closed brake pressure differential switch. The IPC receives a class 2 message from the EBCM requesting illumination.
    • The EBCM detects an ABS malfunction which disables dynamic rear proportioning (DRP) . The IPC receives a class 2 message from the EBCM requesting illumination.
    • The IPC detects a closed power brake booster alarm switch and closed power brake booster fluid flow alarm switch. The IPC illuminates the brake warning indicator and sends a class 2 message to the radio requesting the brake warning alarm.
    • The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for approximately 3 seconds before turning OFF.
    • The IPC detects a loss of class 2 communications with the BCM or with the EBCM.
    Driver Information Indicators and Messages
    The following indicators are used to inform the driver of several different factors.

    Brake Warning Indicator
    The Instrument Panel Cluster (IPC) illuminates the brake warning indicator when the following occurs.
    • The Body Control Module (BCM) detects that the park brake is engaged. The IPC receives a serial data message from the BCM requesting illumination. The brake warning indicator flashes at a rate of approximately twice per second when the park brake is engaged.
    • The EBCM detects a low brake fluid condition or base brake pressure differential and sends a serial data message to the IPC requesting illumination.
    • The IPC performs the bulb check.
    • The EBCM detects an ABS-disabling malfunction which also disables Dynamic Rear Proportioning (DRP) and sends a serial data message to the IPC requesting illumination.

    Here is a description of how the system works But i would check my Grounds and connections
