Remove the wheel and examine the 'tone wheel' (a serrated hub that rotates with the wheel) and a pickup probe that mounts near to the tone wheel. Look for rocks that might be wedged in rubbing on the tone wheel and a bent or damaged pickup probe. Rotate the brake rotor to help find the noise. Also, shake the rotor in and out in several positions to check for loose wheel bearings.

Is it a constant rough sound that increases with speed from the left front?
Then 99% chance of needing a wheel brg on that left front.
Just noise when braking?
Then 99% chance of needing brake pads or pads and rotors.
The ABS light may go out after one or both of these things are repaired.
The ABS codes can be checked for the exact cause and suggested repair needed to correct the ABS system.

These definitely sound related. Need to inspect to see if it's something loose (like a wheel sensor) or the brake pads need replacing, etc. etc...

SOURCE: after replacing the left front wheel bearing on a 2003 ford focus, the abs and traction warning light stay on

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

Why is the left front tire thumping and the brake pedal vibrating when I stop

ABS thinks you are skidding, and is applying the brakes on and off. Likely one of the ABS sensors is bad.

Abs on vr commodore light stays on solutions

Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

2001 Acura mdx abs light stays on. Code reads 04?

I think you pulled the code incorrectly, or are reading it wrong. To get code:
1. Jump pins 4 & 9 on OD2 connector.
2. Turn key 2 clicks.
3. ABS light should blink to give you code. (long blinks for first digit, short ones for second. Example: One long blink and three short blinks would be 13).
Honda ABS trouble codes list :
11= Right front wheel sensor (open/short to body ground/short to power)
12= Faulty right front wheel sensor pulse signal
13= Left front wheel sensor (open/short to body ground/short to power)
14= Faulty left front wheel sensor pulse signal
15= Right rear wheel sensor (open/short to body ground/short to power)
16= Faulty right rear wheel sensor pulse signal
17= Left rear wheel sensor (open/short to body ground/short to power)
18= Faulty left rear wheel sensor pulse signal
21= Continous Operation (chipped pulser)
31-38 are all the same: "solenoid"
51= Motor lock
52= Motor stuck off
53= Motor stuck on
54= Main realy stuck off
61= Ignition voltage
81= CPU (central processing unit)

If the abs light comes on before the front wheel starts acting crazy then it sounds like a different problem..Because when the abs light comes on it turns the system off..it shouldnt activate while the lights on..Check out that wheel and make sure there is no other problems
