I totally agree with everything that [MENTION=150567]Old Red[/MENTION] has stated! I don't know if you've checked... I have back when my instrument cluster "went maverick" and displayed (literally) every warning light/icon on it's processor board, as well as the 'Intermittent' loss of the speed-o-meter, Tachometer, and illumination back lighting! The Cost: Nearly $900 bucks from Toyota parts dept!
BTW: There wasn't anything wrong with the instrument cluster; the Main body ECU COMPU Network lost power and was creating false error warnings, and the OBD-ll stopped communicating! My point is that if you do a search online, you'll likely find a good one (no scratches and a 30 day return policy) at a Toyota salvage parts store for a fraction of that price! 'Best to you',
