Hello. New here. 2014 civic si coupe. P16e3 and p16e2 code, replaced alternator oem, new battery, new battery sensor oem, both new ground straps. Ive checked and tested all fuses, including horn fuse. Ive got continuity in all areas of the lin wire, along with <0.5 ohms of resistance, Ive oscilloscoped the lin wire and it shows good wave form for “data” transfer. Ive cleared these codes a million times, they come back as active codes on my a30m xtool every time with key on engine off. Alternator charges in fail safe mode to 14.1-14.2 volts steady. Any suggestions?
