04 tl

So the other day while driving home from work my Brake, VSA and Yellow warning lights all came on. It was nice out about 40 degrees and no snow or rain.So the next morning I woke up and checked my brake fluid, it was alittle low. I then checked my brake my front pads were low so i replaced them and by doing that my brake fluid went back to full. The lights are still on so I brought the car to an Acura specialist he ran it on has computer and 3 codes came up
1: low brake fluid
2: weak voltage
3: internal power failure

With that he checked a few things but couldnt really firgure it out..Could anyone here possible help me with this problem??

I checked my alternater and my battery both are fine. My front and rear brakes are good.. I cant think of anything else to check and i dont want to get ripped off by the dealer

Thanks

TPMS wheel sensor is going bad (not expensive-- check the 3G Garage), or ABS modulator is kaput (expensive ).

Its not a tpms sensor, and probably not a modulator. You really need to go get the codes pulled at the dealer. Low battery voltage can set off random codes, usually not in the vsa system though. Get the codes pulled and get back to us. The codes you gave us arent even worded the same as acura vsa codes.

Yeah i made an appointment to drop the car off at Acura monday. So as soon as i find out what the cause is I'll let you know

Ok, tell them you want the code and description and let me know.

it ended up being a bad master cylinder sensor. so they changed it and everything is fine now... thanks for the help

I had the same exact problem. I was concerned so I searched this site and found this thread. Upon the dealership scanning, they found "18 problems" at first, but for some reason narrowed it down to "bad conductivity" in the master cylinder sensor. The only fix was to replace the entire master cylinder. Thankfully, I'm covered under the extended warranty I purchased.

They also sold me a brake fluid system flush, which I agreed to since my '04 TL is approaching 100k, so why not?

Not to deviate from the issue here... but is this 40 C or 40 F?!?! either way its either FREEZING cold.. or BURNING hot.. hahaa
