The problem turned out to be the Bank#1 Air Fuel Ratio Sensor (AFRS) according to the dealer that replaced it. Part was $258 USD. Codes clear. I did not have a chance to take your advice to try clearing the codes first.

thks though for the idea, I will try that if other sensors appear to fail.

I will ask them why the AFRS failure sets off VSC and Trac codes, this makes no sense to me.

You should have got one from Amazon (Denso) for 92$ and replace it yourself.

Yes, thks! I know, even a local auto place said $~ 180 I believe for that first sensor.

If I had a lift, seen one done, etc., . . ... I would, wishing I could have. . .

I put a new battery in my 2007 LS460 and it lit up all kinds of vsc, brake, abs, pcs, stop the vehicle immediately, etc. A 30 minute freeway trip, then 1 hr turned off has not changed anything.

Background: no warnings before the dead battery, but the rear window would reverse when it got part way. I was monkeying with it, and found the weather seal crimped right there. I left the ignition on by mistake. 8 hours later, the 1 year old battery was dead. I hooked up a good charger and it nearly cranked 20 minutes later with the charger connected so I left it until the charger said it was done and unhooked it. There were no dash lights and my voltmeter read something like 3 volts.

I pulled it out and replaced it, which cranked right up and runs great, but has all these errors.

Thank you in advance for your advice.
