2018 model: Recently I changed both front and rear brakes with Lexus/Toyota pads. I went to calibrate rear EPC with my scan tool and it tells me it will not communicate or allow me into service mode. I also am receiving a error with my Radar Cruise Control. Is this a fuse relay issue? PCM? TIA Any assistance would be greatly appreciated. Dont want to have to deal with my dealer $$$$.

 

I haven't worn out my original brakes yet, but I've discovered there are multiple youtube videos showing multiple technical approaches to dealing with that EPC brake motor. Here's one:


Here's another:

 

I am past that stage. I followed the first video and it worked out fine. When I went to calibrate with my scanner, that is when I had the problems and error codes.
I checked the fuses and all were good. Im wondering if there is a relay I need to check. Funny that its the EPB and Cruise control error.

 

I did the rear brakes the 9v battery method with no issues, no calibrating or warning lights

not sure what’s going on with yours
