2010 ES350 after resetting the computer a few times with a buddy's scanner, I've come across this A/C code when i run Diagnostic mode (#23) flashing and beeping. can i please know what is wrong? will this for sure fix my issue? I've already driven the car for 60+ miles and no other codes show up. i this really it? AC compressor is running fine i assume other code would've pop up if anything else was wrong with it ?
