the brakes are electronic, alot of times when you do push the pistons back in, the pressure/fluid level in the electronic brake actuator is not within range of what it was when the car was shut off; that will cause caliper codes. I have not tried using a regular scan tool to clear the codes, but all you have to do is clear the codes, it's totally normal. Maybe even take it to a lexus dealership, they might just clear it for you if you tell them you did the brakes yourself. They should know better that sometimes a brake job will cause those lights to come on.

Another thing to try for you DIYers is, open up the bleeder screw before pushing the pistons back in. Of course place a vacuum hose or some sort and drain the fluid back into a bottle. This will prevent the fluid from going back upstream and instead, go into the bottle.

Not so much of a good idea, there is a pain in the *** bleeding procedure on our cars with electronic brakes. If you happen to get air in them, you'll be paying for bleeding brakes. Brakes can only be properly bled with the Lexus scantool. You have to push air out electronically with the brake actuator from every corner. The procedure up there is good for cars without electronic brakes.

The front is very easy. Just take caliper off, use C clamp to depress while old brake pads are still in place, then change. I've done so twice on my 2008 GS 350 AWD. I use the best after market pads with lifetime warranty from AutoZone. No problems in two years.
