Scanner recommendation
The HVAC controls on my 2007 LS460 are acting up. Doing the try to startup then fail. Then if you turn it back on it goes into default mode. Can anyone recommend a scanner that will diag this and if need be test and re calibrate the servos? My gut feel is a bad servo.
Thanks in advance,
John

Welcome to the forum. This question has been posted many times. There's no right answer. Do a search of the forum, you'll likely walk away confused, or look at scanners on web that are for Toyota/Lexus in the $400-700 range and go to manufacturers website. Keep in mind that electronics improve every year and brands that were not recommended a few years ago, may be fine now.

I did exactly as you suggested. And indeed walked away a bit fuzzy. I've been a member for many years. Lurker. There is so much good info here. I see many Techstream devices on eBay that are supposedly the factory tool. But it's all a bit sketchy as to what version does what and whether or not it will work.

Have you done the part where I suggested you do a search on the web for compatible scanners. They're not pirated and do work as described. You can also get a refund..

If you are thinking about buying this, email them xtooldirect@outlook.com with your VIN and tell them what you want to do and they will tell you if this scanner can do it.
Xtool DB7 scan tool/scanner
Xtool also makes one that can supposedly do even more somehow and that one is around $500. But with this D7 model, you can diagnose and turn off CEL codes, test fuel injectors, bleed your own brakes (a scanner is required on my Lexus just to do that) and you can even make your own FOB keys. There's another video on YT where a guy shows how he makes himself a spare key, using this tool.

Scanner / HVAC issues.
Ok so obtained Techstream. Got it running on a Linux laptop of all things. Cheap cable and all. A bit finicky, but reads and controls all. I get a B1497 Lost Communication LC. So it seems as if the AC module is having trouble talking to one of the servos? I don't have a scope. At this point I guess I'll take some resistance / voltage readings after tearing the dash part. Anyone else seen this? Pointers? Techstream was pretty insistent on CANBUS errors. Everything else works fine.
Thanks,
John

If I get just a CEL on the dash, and it's only one code, my 10 year old OBD scanner i got for $25 will at least tell me the code, flash three times and turn off the light. I'm not familiar with the device you are trying to use, if some device in between the OBD port and my laptop would do what an XTech could do of course I'd use it but every cheap thing I've tried so far is useless, that's why I bought the Xtech 7. Going to try it for a few weeks and if it doesn't do what they say it can, at least I have 30 days to send it back.
