Many thanks for this post! However it is actually the OPTION hard button on the right that is pushed and held down while the car is running or not. Turn the parking lights on and off 3 times and wonder of wonders the menu pops up. Push "Display Check" then "vehicle signal check" to bring up the mode that reports battery voltage as shown in the photo below. There are a bunch of other things you can check for dash switches, display colors, radio and XM stuff. I didn't spend much time messing with anything other than read the voltage and watch it while varying RPM. Car not running mine reports 12.2 V and running reports 13.6-13.7 V.

Will this work on my 01? or is it just available on the 04-06?

I've tried this and no menu pops up. Does this work for the 04-06 LS430s only? Am I doing anything wrong?

This is a fairly easy (1-2 hours) DIY using ordinary hand tools. The Denso re-manufactured alternator runs about $150.

JEEZ RKW! What's wrong with you? You're slipping buddy! You used to be SO GOOD, you'd post info BEFORE people needed it! You used to read minds! Now?? It took you nearly 4 hours to post info with the exact instructions with pretty pictures. It took you 4 HOURS to post!!! You're becoming not so reliable anymore. I'm not happy to say it, but it's the truth. What's next?---you posting instructions directly from the book with pretty pictures and links and suggested times and prices and sources to purchase from, like, 12 hours after a member posts? You're slippinggggggggggggggggggggg!!!!

*** the above post is sarcastic. i'm honestly AMAZED how much time and effort you consistently invest into this forum.
I'D LIKE TO NOMINATE RKW AS A MODERATOR!

On a side note, I'm wondering when my alternator will give out. She's got 150k original on it. I'm thinking of purchasing NOW, so when it fails, I'll have it on hand.
