    2012 Corrola Screen Went Blank

    Unfortunately, the fix may have been a very weird coincidence. Similar issue today, though slightly different (display was blurry black boxes, fading at the top, but buttons and radio seemed to work). I tried pushing on the screen again and banging above the hazard button. Neither worked...

    2012 Corrola Screen Went Blank

    Update: Happened again. There were weird characters on the screen and most of the buttons didn’t work. At least this time I could switch between aux and radio. Fix: I pushed slightly on the screen and it fixed the problem… at least for now. the fix doesn’t make sense to me, but there it is...

    2012 Corrola Screen Went Blank

    Having the same problem. Seems to be a common one but no solutions. Even found a video with a good example of the problem. (But not how to fix it) some suggestions that if you hit on top of the radio, just above the hazard button, or push slightly on the display, it seems to solve the problem...

    PCM issues??? (Following new alternator)

    thanks again. I’ve read more and talked to some other people. It’s so uncommon for the pcm to go up that I’m thinking if it is actually bad it has to be the result of something else, and thinking just putting in a new one would fail soon anyway. I cleaned up the terminals this weekend and got...

    PCM issues??? (Following new alternator)

    thanks. I will definitely clean up the battery tomorrow or this weekend when I get a chance. If that doesn’t clear it up I’ll inspect the cables then look into a new battery. Auto zone should be able to test it for me to make sure. I’ll report back if I’m still having issues, before I move ahead...

    PCM issues??? (Following new alternator)

    I have a 2010 carolla with just shy of 100k miles. yesterday afternoon My dashboard greeted me with a flurry of activity. The ABS, Brake, airbag, and power steering lights were all on. Also, the RPM gauge and speedometer we unresponsive and stayed at zero. Finally the left side dash display...
