Hi, my apologies if this post does not belong here, but i am desperate and in need of help. I will be short.
Bought gs450h 2008 recently. It is in a pretty bad shape.
Changed the battery without the memory saver, not a big deal i guess. Battery is Duracel 35/80 as some suggested on this forum. Went to the mechanic for inspection and the check engine light won't light up at all. Mechanic suggests that the check engine light was removed to trick me and make me to buy it. There are some other lights as well which i need help with. Any advice would be appreciated. Is it really missing? how do i know? Any good mechanics that you know in NYC area ? Should i try to sell it to the next unfortunate idiot like me ?

Random facts i think might be relevant :/
*Vehicle starts and drives
*Hybrid system is working from what i can tell, because engine shuts off and it drives on electric.
*Vehicle has damaged front right headlight. (Is broken and not working)
*Vehicle is missing one parking/proximity sensor on rear bumper.
*Vehicle was bought and operated in the USA.
I have attached the video link and the diagnostic report in a PDF format below for more info.

Did your mechanic hook up a scanner? That's the first step.

Get a scanner, and we'll go from there. VSC & BRAKE both lighting up can easily mean a sensor problem

The scanner will throw out all the codes... hopefully. The CEL (check engine light) being on just says that there are *current* (i.e. confirmed and still actual) codes set that are related to the engine - even if it's "deleted" in some way, the scanner will tell you all about them.

Pour some washer fluid in it, it won't stop bothering you about it

If the car's instrument cluster display (the small LCD that currently says "low washer fluid" doesn't say CHECK ENGINE or CHECK HYBRID SYSTEM, it shouldn't be anything serious... then again, you never know.

Again, get a scanner and list all the codes. I wouldn't just clear them, though

Will do asap and will edit my original post with details. Unfortunately, check hybrid is on.

Also if you or anyone could point me to the right direction on this forum, where to look for compatibility information for the third gen gs models? Like of the parts from gs300 or gs350 will fit gs450h?
Thank you

This thread covers sites for schematics and part referencing. It also mentions the reason why a certain site can't be posted here.

I'll add https://techinfo.toyota.com/

Parts compatibility:
Engine - any 2GR-FSE engine should do, the oil pan & intake vacuum tubing might be different across models. 2nd gen IS350, 3rd gen GS350 are the best bets. Cross reference bolt by bolt if it comes down to it, though - not something that's to be taken lightly
Transmission and driveshaft are unique. The driveshaft guibos/rubber bushings/whatever they're called MIGHT be shared with the Supra TT/LS400/GS430/etc "v8" guibos from the past, but they have to be measured. The two needed cost almost half the amount of the driveshaft itself, unfotunately... not that they fail very often - in my case the diff's backlash is out of adjustment.
Rear differential and drive axles - anything from the IS350, IS-F, GS350, GS430, GS460. The rear diff in the US is 41110-50230 - certain LS430 and SC430 model years/transmissions use it ( I think all the 6-speed ones), along with the GS350 (at least the RWD) and GS430 (3rd gen). Older "big diffs" bolt on as well, but the axles need modifications.
Chassis - the 2IS and 3GS share mostly the same platform. Subframe is the same on the IS350/IS-F/GS350/430/450h/460, the IS250&GS300 use the "small differential" subframe. Rear knuckles are the same. Front knuckles check out as GS-specific. Most common handling mod - GS-F or polyurethane front LCA bushings (the big ones), stiffer sway bars.
Hybrid inverter - unique to the gs450h, LHD and RHD-specific.
Hybrid battery - 40 6-cell 6500mAh NiMH modules. Used in most Toyota/Lexus hybrids. Notable exceptions - anything with li-ion, rx400/450h (9-cell modules), ls600h (12-cell modules), the new Century (same as the ls600h, doubt you'll see one at a scrapyard soon though ). Since you mentioned that the car does run on electric power alone, that's probably not a concern for now.
Brakes - electric motor-driven brake fluid accumulator, unique to the GS450h. Lexuspartsnow lists the 4th gen 450h's brake accumulator as a compatible "updated" part. Calipers, pads, rotors - shared with most of the IS/GS/RC range.
Body parts - I'm guessing most are the same. Again, cross-reference. Not sure if all 3rd gen GS models have the adaptive headlight steering. The parking sensors should be the same, though.
Specifics - check or ask

Show us some pictures of the damage, we might spot something non-obvious. Hopefully no bent frame components, but I'd check it regardless

The diagnostic report appears to be for the engine ECU only. No trouble codes (DTCs) set, I guess the car hasn't been driven enough for it to warm up properly (o2 sensors and etc). At any rate, can't spot anything bad on the report. Your VIN is visible in the PDF that you uploaded, it's not only at the top.

Try scanning with torque (android app). It did pull hybrid ECU codes on mine when they were set. Best would be techstream - you'll need something like the mongoose pro, tactrix openport (easy to get a genuine one since you're in the US) or vxdiag vcx nano. miniVCI (only version 2.0.4) might also do the job, but let's say that it's not so great

I assume you have an OBDLink adapter - if you do, http://hybridassistant.blogspot.com/ - once you get it running of course, this doesn't really help much with troubleshooting

A lot more lights than just the CEL don't illuminate:
https://www.clublexus.com/forums/gs-...fferences.html
Master warning light, power steering light, VSC light.

Seems like it's been driven... have you noticed any issues with the brakes? Wondering why they're lit up, probably a sensor somewhere.

Seems like the car runs fine.

The hybrid battery pack causes the vsc light alot of times.

The check engine light comes on in my car because the cat needs replacement, when the traction battery service is on I get the red triangle.

Apparently the car is running on electric power, so I'm doubting that it's the battery itself (or the inverter or anything along the lines, really). Check VSC lights up for a ton of reasons on a ton of lexus models

I'm more worried about the missing 3 lights and the BRAKE light. Without a complete scan we can only guess... especially given that the car appears to be running fine.

Update.
Long story short, lights did not light up because, of the previous owner. He used black tape to cover up the lights on the instrument panel. I had to take apart the whole panel and gauges to get to it and remove.
Check hybrid system with the problem code of P0A80 had to do with faulty hybrid cells and Corroded bus bars. voltage was abnormal due to poor state of cells and aforementioned busbars. (solution bought 40 third gen prius battery cells with brand new nickel plated bus bars and replaced it all, works like a charm.)
However there is this annoying P0517 code that keeps bothering me, and it has to do with the sensor, i think. Reason why i think it is a sensor, is the missing temperature sensor on my 12v battery. Need your help to find the part because i was not able to locate it by google search or any other means that i had so far.
The picture clearly shows what i am talking about in this thread :

Thank you in advance.
