Help!!
Did you find a fix??? Mine just did this... HELP
Hello friends.
I was using a 12v battery to manually power the electric motor that is attached to the rear brake piston in order to release pads. Everything went well and I got new brake pads, but after turning on the car I got a dashboard error - "Electronic Parking Brake Malfunction. Visit Your Dealer."
It turned out there is an EPB Service mode I should have used to replace pads but I did not know about it.
Does anybody knows is there any way I can get rid of this error or reset EPB without connecting to a computer or other devices. Or maybe you know where I can get a device and what device to get it calibrated.
Thanks in advance!

Stop !!!!!!!!!
OK So, I found this video so it does not need the any diagnostics tool. You just remove the one side connector for parking break and it will completely retract the other connected side.

Are the sliding pins moving freely? How long have they been in the car for? I would clean and re-lube pins and lube ears of pads. I find myself having to do that every 2-3 years on my cars w/ sliding calipers.

Pulsating brakes are almost always caused by warped rotors. Excessive hard braking or fast stops will overheat the discs and can cause them to warp. Slider pins that are sticking or a caliper piston that does not completely retract can also cause overheating. If pulsating brakes occur occasionally like during wet driving conditions it could be the ABS system. New defective rotors are also a possibility. I would take the car to Lexus and see if the warranty covers it.

Another cause of pulsating is build up of brake junk on rotors. Had this all the time on an Accord. The junk gets "attached" to the rotor and you think it is warped. Rotors on the Accord were soft. About every 6 months I would find a long straight road with no one in sight and do really hard braking about 5 straight times from 60 to 0. Eliminated the pulsations every time.

I usually only wash the car when cold. I check the rotors temp before spraying the car.
