1990LS400

About all I can do it to provide a link to a ClubLexus thread which talks about the calibration: http://www.clublexus.com/forums/rx-second-generation/611147-how-to-reset-vsc-off-warning-light-and-traction-control-light.html I don't think I've sever seen anyone report a yaw rate sensor failing but that doesn't mean it can't happen. That the problem arose after the alignment seems fishy. The first thing I would wonder about would be that Firestone disconnected or damaged a wire underneath your vehicle. As a chain Firestone has never been well regarded and they tried a major scam on me the one time I took a car to a Firestone store many years ago. You could ask Lexus corporate for participation in the replacement cost if not total compensation if the sensor really does need replacing since your RX is only 5,000 miles out of warranty. If you register with your forum member name, the yaw sensor is only $635.27 from http://lexus.sewellparts.com/oem-catalog/841484A233-Electrical-RX350-2010.html in Texas where I've bought parts over the years. Retail price is $1032.96. I have no idea how difficult it is to replace.

I've only watched while a Lexus dealer service writer programmed new keys and I do not understand whether or not an existing master key is needed to program a new master key. I wouldn't think an existing master key would be required since your valet key has the transponder chip that allows it to start the engine. Best I can do is to provide a link to instructions I found on the Innertubes: http://www.keymam.com/ru/news_view.asp?newsid=58 You might google for other instructions since the link I provided is obviously for Russia! You might ask at your nearest Lexus dealer.

I suggest you leave it alone. I don't know if it is still the case but the way your tail/brake lights are wires has in the past been a requirement in many countries to make it more obvious to drivers of following vehicles that brake lights were being applied ... i.e. so that taillights remained in their normal steady state when brake lights lit up. Germany went one step further and prohibited any rear bulb from being used for more than one purpose. The U.S. has for many years increasingly been a follower instead of a leader in these safety standards.

These don't work?: http://www.autoanything.com/lights/60A1218A0A0.aspx But why bother.

Got Google?: http://www.google.com/#gs_rn=22&gs_ri=psy-ab&cp=12&gs_id=19&xhr=t&q=headlight+covers&es_nrs=true&pf=p&output=search&sclient=psy-ab&oq=headlight+co&gs_l=&pbx=1&bav=on.2,or.r_qf.&bvm=bv.49784469,d.eWU&fp=8b6db1e58467963&biw=1920&bih=974 One of the great aspects of plastic headlight lenses, other than they are a lot harder to break than glass lenses, is that they can be easily and inexpensively restored to like new condition when they are worn to the point that they look like they are ruined and are putting out little light. If your lenses are looking worn, buy a restoration kit at an auto parts store.

The horn in my similar 2000 LS400 stopped working last summer. I rarely use my horns and discovered they had quit working only when my own wife damned near backed her Camry into my LS in a nearby shopping center parking lot. (It's a long story. Don't ask.) The problem was the horn/airbag pad. The pad would not depress properly and it was obvious that something like a spring inside the pad was broken or weak. It my case the problem was on the right side of the horn pad which makes sense I guess since I am right handed and use my right thumb to honk the horn. The horn worked intermittently for a few days and then stopped working entirely. The indie repair shop I use replaced the horn pad/airbag assembly with a used one. I think the total cost was around $750 - certainly not much more than that. A new horn pad/airbag assembly was something like $2,000+. I was told that the horn pad could not be disassembled and repaired. I have the old one out in the garage - had planned to tear it apart to see how it is constructed but never bothered.

Paranoia about the water pump isn't bad since I had one fail on my first Lexus (LS400) at only 75,000 miles. With that said, I think your RX is a lot more reliable than that 1970 Volvo you had. I'm a "three time loser" with Volvos: 1972 145 wagon, 1973 P1800, 1978 242DL SRO - sold them all between 1978 and 1979.

It's never a download. You can tell what you need at http://www.lexusnavigation.com/what_to_order.php

A better question is when is Apple going to "get a clue" and start adhering to industry standards for these functions.

You can view the owners manual online at https://secure.drivers.lexus.com/lexusdrivers/home where you can also view history of service performed by Lexus dealers. You might want to obtain a hard copy. Having recently replied to another IS250 owner about A2DP Bluetooth audio streaming, I am quite certain that the 2010 model year was the first it was available on the IS250. There are a variety of ways to add A2DP Bluetooth with a popular one being the Blackberry gateway: http://www.google.com/#gs_rn=21&gs_ri=psy-ab&gs_mss=black%20berry%20gat&pq=black%20berry%20gateway&cp=5&gs_id=39&xhr=t&q=blackberry+gateway&es_nrs=true&pf=p&sclient=psy-ab&oq=blackberry+gateway&gs_l=&pbx=1&bav=on.2,or.r_qf.&bvm=bv.49478099,d.eWU&fp=4bbc3b97318d8904&biw=1600&bih=877&bs=1 I don't know offhand if sat a sat radio receiver was standard for the 2008 model year - maybe the nav or owners manual will tell you and also tell you how to get its ID code if it has it. I do know for certain that for earlier model years a sat radio receiver was not standard and was a dealer installed option. The going price on eBay for an add-on sat radio module that integrates with Lexus nav is only about $150.

Yes and you will also find some extra connectors for missing options in some Chrysler/Fiat vehicles -- but not (OK, almost never) in vehicles manufactured by Toyota be they branded Toyota, Lexus or Scion. Toyota, unlike some lessor (and less profitable) companies, milks every yen of profit by including only the infrastructure required in each vehicle. OMG! We finally know why GM had to be bailed out by American taxpayers and why Fiat rescued Chrysler as it slid into oblivion - gasp ... it was due to the cost of putting in all those damned extra connectors in their vehicles! :whistles: I recently installed a DRL kit in our 2012 Toyota Prius v wagon. DRL is mandatory in Canada, all EC countries, Australia, etc., etc., but there is not a signal DRL-related relay, cable, or fuse in our U.S. specification Prius. Same with the OEM turn signals I installed in our Prius's side mirrors - standard in most of the rest of the world - but not for the U.S. and Canada - but absolutely no infrastructure for them in our Prius ... I had to fabricate and route all the cables and electrical connections. I've run into this situation over and over on vehicles made by Toyota and other foreign manufacturers - it's just the way it is.

No, you absolutely cannot easily add options like you want - except for remote start which is always a dealer installed/aftermarket option. Wiring harnesses are completely specific to a car - there are no extra connectors lurking about. If your car doesn't have memory seats then it doesn't have the ECU(s) to control them. Consider selling your car and buying one with the features you want. It costs vastly more to add options than to purchase a car with the features you want.

Unfortunately the Gates manual you referenced has numerous obvious errors but at least it is more accurate than older versions.

Do the high beam DRL (daytime running lights) also not work?

Don't stop there if you have the time and a fast internet connection. You might someday like to have the repair and wiring manuals and other references such as accessory installation guides.

The installation instructions may be viewed and a remote starter purchased for $170.15 at http://lexus.sewellparts.com/accessories-catalog/viewall/HS250h-2011/2432.html if you register with a car forum member name. Looks like a "Techstream" is required to activate a remote starter. Remote start seems an odd feature for a vehicle whose gasoline engine normally doesn't run when the Start button is pressed. I'm curious as to why you want one. We have a Prius v wagon with the Advanced Technology Package and also live in Kansas.

A US$15 2-day subscription to https://techinfo.toyota.com should provide what you need as long as you have time to download and organize the reference materials which I think, from my limited experience with it, are all in PDF format. The techinfo website was formerly available only to U.S. residents .... noticed in the past year that it had been opened to Canadians.

You chances of buying a 2010 RX350 at the price you want to pay appear to be low to non-existent based on the prices shown for thirty 2010 RX350's on Sewell's website: http://www.sewelllexus-dallas.com/VehicleSearchResults?search=preowned You might as well stay home unless you can come up with $5,000 to $10,000 more.

Are you certain that both the handsfree phone feature and the audio streaming feature are connected? i.e. handsfree can be connected without the audio streaming feature being connected - they are separate features on Lexus Bluetooth systems and have to be connected separately. I just went through this two days ago on a 2013 ES350 loaner - separate connections for handsfree and audio streaming ... works exactly like the similar system on our Prius.

Drink up, Randy ... and enjoy the benefits of improved methods and equipment.

I'm pretty sure that the mechanic who explained it to me wasn't watching out for the dealer. He seemed like a complete "techie" and launched into an enthusiastic detailed explanation about the interrelationship of components that got my eyes glazing over pretty fast. So, I did some Internet searching ... it must be true if it's on the Internet ... right? I quickly found web pages that said the same thing including the following one from good ol' Pat Goss who says "Most manufacturers have stated that you no longer machine a brake rotor off the car. It has to be done on the car such as what we are doing here." --> http://www.motorweek.org/features/goss_garage/turn_turn_turn_that_rotor Gosh, I think I am learning something new!

Sewell Lexus in Dallas has some of the best prices I've seen including shipping: http://lexus.sewellparts.com/accessories-catalog/Service/GS300-1999/5781.html I've bought parts from them several times and have found them to be helpful and quick. Register on the Sewell website with your forum member name to get even better prices.

Your posts are timely in that just last night when I picked up my car a Lexus dealer mechanic explained the same concepts to me using very similar language. He told me that he removes and machines rotors while off the car only in unusual circumstances and that the best results are obtained when the rotors are machined while on the car.

A $15 2-day subscription to https://techinfo.toyota.com/ might provide some useful information. I don't think it will include information about the conversion which I would have thought would have come with the conversion kit like it did with the conversion kit for my 90 LS400 over 10 years. Maybe you will also find some help at http://www.lexls.com/tutorials/air/

Your description of the noise sounds like one I had from a failing catalytic converter. How did they check the cats? Remove and shake them?
