Hi guys, on the weekend i replaced my rear pads and rotors. After completion, i took her for a spin, and found the brake light on. I put the car back up on the jack and replaced the brake sensor with a used one i had lying around. Now all 3 of the lights mentioned above are on, along with the engine light. (all of which were not on before)
Any thoughts?

 

maybe the ABS sensor got disconnected? did you drive the car afterwards so the computer can do some math and turn off?

 

any updates?

 

If you spin only the rear wheels or only the front wheels, ABS warning will be on until you drive the car normally.

Did you have the brake light on before the change? (asking for service)
Maybe you need a reset from the tach.

 

I believe it's a wheel speed sensor. I talked to mini the other day about it they said that's more than likely what it's from. Also the front two are more susceptible to becoming dirty/breaking.

 

I scanned it, it says RR speed sensor. Which is weird, this only came on when i replaced the brake sensor.

 

As MiniToBe said, check the speed sensor connection.
Brake sensor is on the RR too and you was working on that area

 

You might have bumped the connection at the wheel speed sensor with the brake pad sensor. They have to be clipped in and set. Did you maybe mix up the two? Also it has to be clicked in all the way..

What scan tool do you have that will let you know that?
