I need some help. For the last week my brake light has been coming on when I depress the brakes, despite full brake fluid, then last night my ABS and TCS lights came on. At first, the TCS light would come on and a humming coming from the front right wheel. Also had a slight ticking sound everytime the light would flash. Once both lights came on the car ran fine. Had the car checked for codes and nothing showed up. What could be the problem?

- Brake light came on when brakes depressed. (off now)
- Ticking and humming sound everytime the TCS light came on
- TCS and ABS light on car ran fine.
- No codes

HELP!

brake fluid light may be coming on due to a faulty sensor in the mc reservoir cap. everything else sounds like the trans goin..

 

Had the EXACT same problem on the left front a few weeks ago. The humming sound for me was the ABS self-test occuring frequently since my speed sensor went bad. I replaced that ($36) and it's fine. Now I can't figure out which plug to use the "paperclip technique" on to turn the F-ing lights off. If you can help me figure that out that would be great.

 

Sorry to Jack up your thread but, I have the same issue, Humming, Usually happens when i Drive forward after the car have been parked for a while, it will Hum and then stops, Which speed sensor was bad on yours? where are the speed sensors, how do they look like? any pictures?.

One thing: I ve no warning Lights on My DASH!...,

Thanks,
R.

 

UPDATE: I had it looked at today and the mechanic hooked it to the ABS computer, found out that the LF Vehicle Speed Sensor went bad and a PFINH Signal Malfunction. WTF is that?

As far as what the sensor looks like , remove the wheel and look under the car. There will be what looks like teeth going around the wheel with a part bolted onto what I think was the A frame. There is a rubber tube coming down with one bolt holding it to the wheel. That is the front Vehicle Speed Sensor. Sorry, cant scan so this is the best I can do. If anyone has a scanner, its on page 19-73 and 19-74 in the service manual.

 

I believe this is normal, self test for ABS.

 

Yeah - mine does the same.

Sounds like ABS kicking in for a split second once I hit about 3mph or so.

 

Yea this was discussed not to long ago..........its normal

 

i searched and couldnt find anytin...but its seems as my tcs buttom doesnt do anytin...i push it in and no light comes on...and it doesnt even feel like you pushed anytin....you push the cruise control button and it clicks but the tcs button goes in and out like nothing has happen....the weather been good so i havent needed tcs...but if i wannted to turn it off for any apparent it doesnt let me??

 

??

 

Did you ever figure out a way to reset your abs lights? Im having my sensor replaced but i know that the lights will remain on!!!

 

i had the same thing i think it was my thread u were referring to... it's the self test abs when u start the car and drive for the first bit it does it twice for me...the maint'requ light and a bunch others blink a few times (some more than others)... and hopefully they all go away and ur good.. lol..

for me no light are on when the self test is done at roughly 20-30 meters after driving forward for the first bit
