Actually you take your car to autozone and they use this reader that is about the size of a cash register laser gun. They plug it into your car under your steering wheel and read the codes. It's not rocket science......and it's free.

After lunch, he called me and said they did a pressure test on the emission system and could not find any problem so they reset the system and my car is ready to go. Just picked it up, hope the CEL won't come back any more
2jz,
I also checked with him, the charcoal canister is not covered under the emission warranty. Only the cat. convert is.

Kool, that's what they told me. They put some smoke into the system and presurized the whole system to detect the leak. No leak at all. But unfortunately, after 20 miles of driving, the CEL came back on again. I have another appointment to bring my car in on Monday

Well I was kinda messing around with my car, Kinda blindly tinkering with the evap system. Checking the fuel cap, etc. etc. ... Reset the ecu. Everything was peachy for a couple of hundred miles and then, then the light came on again. 
I'm trying to weed out the cheap fixes. On my Supra, I know I can disable many of the tree hugging systems with out ill effect. I'm just not sure about these newer systems. Just a vapor canister form jay marks toyota is like $463 at the discounted price.. I guess i'm just a cheap arss, especially when the systems malfunction doesn't hinder the cars performance. It just gives me that annoying light...
I'll update my findings...

Got a call from dealership after two days of diagnosis. Need to replace charcoal canister and vacuum switching valve. Parts+labor $1100 
They still insisted it's not covered by any warranty. Does any one have some copies of EPA papers that you can send me so i can go fight with the dealer? HELP!

My 2001 Toyota Sequioa had the same problem last week. Charcoal canister and vacuum valve switch. Those specific parts are not covered under the Toyota 8yr/96,000 miles plan. I got it done at Toyota Service for $900 (ouch). Maybe Lexus might be the same way.
