The LS600hL did sell in the US. Just without RHD. There are probably some other localization changes, but the majority of the car is the same.

TIS is the Technical Information System . It is $20/2 days. you cant download a whole manual at once, but you can download individual pages pertaining to systems . Many people plan a weekend of downloading and grab the whole thing. If you dont want to do that, just download the AC section, and all the code related links from your test mode results, then download all the links that those files point to . After that, anything else you might think you will be looking at. Inevitably, you wont download the one you need later (ask me how i know ;D ) but its a very important site for anyone doing Toyota DIY.

The manual will have different part numbers for some items because of RHD/LHD and the recalls, etc will not pertain to your car, but the majority of the info will be useful. Unless you can find a lexus info site for your country, this is the only method you have. DO NOT get an Alldata or Chilton guide, theyre absolutely useless (ask me how I know ) . Oh would I love a hardcopy of the manual, but I dont have hundreds of dollars for the series.

A handheld scanner isnt going to give you the detail the Techstream does. It also wont allow you to access the servo door calibration. Techstream is indispensable for electrical issues.

Make sure that your using Internet Explorer when you sign up for TIS because it won't work correctly with any other browser. I downloaded the whole manual in 2 days right after I bought the car but you don't want to try that if your trying to troubleshoot your problem. I was literally downloading every hour I was awake for 2 days while trying to keep all the PDFS organized. You have to download each page separately. Go into vehicle interior and there should be an air conditioning section. Just download EVERYTHING and if you still have time left download anything else you might want.

What did you see in IE you didn't in the others, @sha4000 ? Ive used Firefox, Chrome, and Safari and they all looked the same on my end. Even mobile browsers worked normally. Was I missing something? I feel ripped off!

As predicted earlier my Foxwell Scanner wont interrogate all the various systems in the Lexus. It will read basic codes (of which there weren't any relating to the AC system) but wont actuate the servos etc, so I've bought the Techstream system. Just waiting for it to arrive and then lets see what it says!

I dont want to start ripping my glovebox out without knowing that the amplifier/servo behind it requires attention.

@b9boy I see you responded to someone else's thread about this issue. I'll respond here in the hopes of getting this thread back on track and not spread all over the forum (for future user's sake). For other's future reference, here's the other (wrong?) thread. I'm not meaning to chide you, just hoping to keep the info together and help you.

In your photos on the other thread, there are dozens of items that are in white with an asterisk. As it says at the top, that indicates "ECB not supported or not responding". Obviously, the car is responding to a lot of these, and they're functioning, or your car would be lit up like a Christmas tree on the dash (ABS, Suspension, etc).

You might/likely have a version issue with your techstream. As I've said before, you will need to find a version that works. Sometimes that's a newer version, sometimes an older version. There are versions that don't give you access to systems in some models/MY's, or that have bugs. Sometimes it's a setting for the country, sometimes it's the cable (but not too often any more). I had to try 4 versions i of Techstream w my 460 before I found one... I had to try 3 versions with my Rav4EV. My father spent like a week online trying to find one for his Prius Prime (and he's not too senile &#128518

Download, apply patches, try with car, repeat. Start when you have time and patience, and a charged laptop battery. It can get frustrating. Eventually it will all work.

Also a reminder: don't post links to this software to download, or this thread will be closed. It's not "official" and consideted piracy by the forum . I don't think we're allowed to coach you on installing the patches, either, but Google can help.

b9boy

Thanks unabee - i hadn;t realised embarrassingly that i was posting those pics on someone else's thread! I did that on my phone and thought it was my thread....red faced now!!

I'll try another version of Techstream then and see what happens.

As you say my car isnt lit up like a Christmas tree dash lights wise so most things must be working, and I did wonder why there was a comms fault. I assumed it was the car rather than the software compatibility. I'll also try and have a look at the servos as mentioned on the other thread and see if i can see them working.

b9boy

ps perhaps its worth me stomaching a code read by an official LExus dealer to at least determine which part is faulty, and then getting an independant garage to effect the repair?

unabee

That could end up being very expensive, too. The dealership will charge you for the scan, and you'll have to pay again at the independent shop. Maybe still cheaper than going full dealership, but it's maybe not practical. Also they may scan the code, clear it and test it is all good, then give it back and a week later the problem reappears. At least if you have techstream running, you'll know you're not being lied to, and you can run the servo calibration before and not have to pay for them to do it.

I understand wanting to throw in the towel. It's up to you. We're all here willing to help though if you're willing to keep trying.

Do you have any Toyota specialists near you? Or a hybrid specialist? They'll have techstream for sure.

I would not got to Lexus just yet. They will read the code and proceed to tell you that lots of things need to be fixed.. I've had great success using techstream 10.xx the newer versions would not play nice and some things were missing. Did you check the temperatires of the inlet and outlet heater core hoses?

b9boy

I've been trying to find a specialist locally but so far I've drawn a blank. I'll have a look for a Toyota one because as you say they should have Techstream. In the meanwhile I'll buy another version of Techstream and see if tht works (Ive tried two now)

b9boy

Ah, interesting. So I'll try and older version and see what happens then. So far I've tried V13 and V14. The first one wouldnt talk to the car at all. The second brought up the results I mentioned (and posted here again)










The car is currently at my local garage having a suspension rattle diagnosed (I suspect I know what it's going to be...) so I've asked them to scan the car for codes using whatever software they have. It wont be Techstream because they arent a Lexus specialist but all info is helpful and they might uncover something you never know...

Check the heater core hoses.

b9boy

Thanks- I'll ask them to check those. I couldnt find them when I looked.

b9boy

I have to say though my gut is telling me its an AC amplifier or Servo problem.

Something somewhere is just not telling the car to blow hot air on the left hand side of the car. It doesnt feel mechanical, it feels electrical.

I hear you I felt the same way and I investigated this issue extensively for 2 years before I pulled my dash apart and changed the heater core which fixed the problem. I would flush the core and get some heat and then I would lose the heat again eventually. With Techstream you can test all the servos to see if they are operating. If you pull the glovebox on the passenger side a and the trim beneath the steering wheel you can see most of the servos in action. I even purchased a used AC amplifier off ebay to rule out mine and the problem still persisted
