Does anyone know anything about these? Like what to repalce or where the part is located? (C0236) this one I understand. The master cylinder needs to be replaced. I'm lost on the other three. Sounds like I'm in alot of trouble...

I think EBCM has something do with the brakes? Someone correct me if I'm wrong. I tried to search for you but no results.

the c1256 condemns the electronic brake control module right off the bat. its a code for an internal malfunction with the controller itself which is built into the ebcm. that will have to be replaced before anything else. but it wouldn't hurt to inspect the wiring and sensor and hub bearing for the wheel that its throwing the code for. perhaps something in the road flung up and broke the wire or there is excess rust build up on the tone ring that the speed sensor picks up it signals from . start shopping for a ebcm to start. of course, don't let people diagnose your car via internet, its always worth it to have a legitimate lexus toyota technician diagnose it properly.
