Interesting! I do have an XP machine and other OS to try. I play with mechanics when I feel confident but I'm in I.T. lol

The BT OBII and Techstream CD /USB cable for Toyota / Lexus are both on their way, so see how that goes when it arrives. I might try to find the brake light sensor, I don't want to jump the gun before scanning it but the previous replies seem pretty confident!

Thank you all for the response and clarifications so far

Bingo! I used carista with a generic BT reader and an old android phone. I also got bonus codes, yay. But there's no fault lights on the dash? Interesting.

so, you are driving a broken car. big whoop...HVAC codes aren't errors... It's just you scanned in the dark or a garage.
ABS errors most probably history. That is why you need techstream, not 'old android phone' and some 'app'.

ps. my bet won, as usual ) where do i collect my winnings?)))

capt

oh sweet, yes it was in a garage so today at work it only shows the other four. At 92k miles the actuator was replaced so history would be great! The tech stream disk and cable are in the mail, see when that baby comes in.

self actualization is the prize! Haha

Did you try resetting the codes to see if Cruise started functioning normally, at least for a little bit?

capt

No ive left the errors as is, I'm thinking the other scanner is coming no later than tomorrow. I kind of want to see what it brings up before clearing them. I did buy the brake switch just in case, it was inexpensive. Now to see where it's at exactly.

Lynzoid

Near the brake pedal obviously. Easy to replace if you got hands. Just don't forget to tweak it so brake lights come on at the right moment.

capt

Thanks for the tip, the brake switch is installed and the lights come on as it should, it was adjusted as needed. Cruise control appears in the dash without blinking, now to test drive soon!

capt

For anyone curious about the exact location above the break pedal. Two Phillips screws were the only things that needed to be removed (below the left and right of the knee airbag) in order to release the plastic panel above the gas and break pedal.

Nice one. My bet won.

Good assessment........

Sure did! Ive been using it just fine these last three days. It was a 25 dollar part 84340-30110 if anyone is looking for stop lamp switch for the 2008 LS460 Base.

Seems to me, the symptoms for a maladjusted switch and a defective switch would be the about the same. Any failure analysis on the removed switch - is it bad?

capt

not sure about testing the old one but the stop lights worked just fine prior to its replacement. I adjusted the stop lights to come on about the same as the old one though.

Lynzoid

Two pairs of contacts... Second one is a failsafe. One of those goes - stop lights still work, but cruise gets inhibited. On older cars they even used a vacuum valve (inside a brake switch) as a failsafe...
