VSC, ABS, Brake Lights on After Brake Job
With help from a friend, I recently turned the rotors and replaced the brake pads in my 2008 LS460 with ceramic pads by Akebono. We didn't follow the right sequence so before releasing the automatic parking brake, I pushed the brake pedal to start the engine forgetting that one (driver-side front) of the old brake pad sets had already been removed - the consequence was that one of the brake pistons was pushed out beyond its norm (not completely out) and brake fluid oozed out . . . We pushed the piston back in, bled the fluid line and all seemed to work well just as any new brakes would (slight hesitation as the pads are being broken in, particularly after a few miles as the brakes got hot - expansion)
Well, my problem now is that despite the new brakes appearing to be working fine, the ABS, VSC, brake lights are on and we don't know if something is wrong, or the brake system just needs resetting.
Have any of you LS460 owners in the forum experienced this problem and how did you get it fixed? If this was a dealer job, how much did it cost to get it fixed/reset?
Please note that the brake sensors were carefully removed and reattached; i.e., no damage observed.
Thanks for your help!

It sounds like you will need to get it reset. Try discounting the negative battery terminal off and wait a few minutes and reconnect. Hopefully that will help, if not you will need the dealer to reset it.

did that on a caddy once and i ended up screwing up the mastercylinder this seems like you might want to bleed the master cylinder or just reset it an see if it goes away.

you need to bring your car to dealership to reset the computer
never do brake jobs on the ls460 with the battery connected. even if you didn't have the mistake with the pads / pistons, bleeding alone could throw those lights already.
try disconnecting the battery and see if it resets, otherwise, time for dealership

I'm planning on switching out the rotors and pads soon. Would a regular brake specialist shop not follow proper procedure? I'm hoping the dealer wouldn't mind switching them out for me, but it depends how much they charge me.
I would def take it to the dealer. Hope everything gets resolved!!

the thing is when brake fluid goes in the wrong direction or anything out of ordinary, it triggers the codes and have to be cleared at dealership. so what my guy did was to disconnect battery completely before installing anything.

Bleeding the rear brakes on a LS 460 is different than the front. Doing either wrong will set off the light show. But it can be done in a driveway without disconnecting the battery. But that's for us pro's to do.

dont need to even mess with the pistons when doing the brakes, with that being said dont really need to disconnect the battery if you know what you are doing. rears are different from front, front pads slide in and out without removal and rears if you take em
out in two pieces your fine.

Also, any suggestions on how to adjust the rear automatic parking brakes to make sure that the right clearance between the brake shoes and the inner surface of the rotor is achieved?
Thanks again!

once you take the rear rotors off there is a sprocket like mechanism that you can use to adjust the parking brake since it is drum like. if you take the rotors off you will see what I am talking about, and make sure your parking brakes are off lol. not sure which way but one way is tight the other way is tight.
