So recently I've replaced my Electrical power steering ECU and my electrical power steering rack because the dealer said that's all I needed to do to fix my issue from before.(Quoted me freaking almost 6 grand for a new rack and ecu, did myself cheaper with working parts) Now the PS light is still there and its reading code C1528 and C1336 on my lexus gs300 AWD 2006. I cleaned ECU connectors with cleaner, and Im pretty sure its getting communication to give me codes. Also my battery voltage is fine. Any ideas what? I heard some people mention reprogramming ECU and calibrations, but I don't see any calibration files for these things for TIS, techstream.
