At least the TS508 prochure says it supports both frequencies... do you need to somehow select that in the tool/menus? Are you sure that your sensors are sending and not out of battery? BR.Sami

Are you able to see the live data monitoring of the sensors with your OBD tool? Like with TechStream? Do you see that the three sensors are there and sending meaningful values (e.g. if you let some air out of the tire, that is visible in the readings)? If yes, then that scanner somehow failed to read the IDs... I've had bad experience with the Schrader TPMS sensors: I once replaced all 4 sensors with new Schrader ones (not EZ series). They worked most of the time ok, but time to time caused error messages (check system). So, I had to swap back the OEM sensor (with new batteries).

That is 14.2mm BR.Sami

Here you are... BR.Sami

At least on Android phones, you can have one BT device per profile (e.g. one for phone calls, another for streaming, etc)

You will have two BT connection: one to the OEM handfree and one for BT streaming. And these are active at the same time (this might be the reason the GTA BT connection setup fails time to time, as the phone needs to setup two connections about the same time). Anyway, the car will do the switching (it does not even know that there is another BT connection, it sees that as an ordinary CD player). Works at least on my android phone, where you can select the correct BT profile for each BT device separately (allow only "media audio" for the GTA car kit, no "phone calls"). Another note: if you use your phone's navigation (e.g. Google Maps), you need to switch to the BT streaming music to get the vocal guidance audible...

Hi Paul, I've this one: "1 x Pure Bluetooth Kit for Toyota and Lexus - 2 Gen (PBT2-ToyotaNav)", at least that is what is written on my order... I ordered that about 3 years ago, and got it shipped from UK (that was one of the reasons I ended up with this product) When I was installing the GTA Car Kit, I found some strange IPOD-adapter from my car (using the same CD changer port). Probably the previous owner has installed one, so I just removed it and replaced with GTA kit. Installation was very easy thanx to the nice videos on YouTube: One note still: I did not install any mic as I'm using the car's original BT for handsfree phone calls... AUX was not needed either as the 2008 model has AUX already. BR.Sami

Hi, I've a BT kit from GTA Car Kits (https://www.gtacarkits.com/) in my GS450h with ML. It will connect to a free CD changer port and the ML system thinks it is a CD player. And the steering wheel buttons do work (play/pause, change track). Time to time the BT connection fails in startup, but otherwise it has been working nicely... BR.Sami

Hi, At least in my GS450h from 2008, the standard tire size is 245/40 R 18 W (other allowed: 235/40R18, 225/45R18) Rim: 8Jx18 ET45, 5x114.3, center hole 60.1mm Check the clearance to brake calibers, especially in front... not all aftermarket rims will fit... BR.Sami

Lower limit not changed after 24h and about 125 miles... still monitoring it...

Ok, now I was able to get few screenshots from my car: first one is before pressing the init/reset button: You can see that the "lower limit" is actually the lowest value of those thresholds... then pressing the init/reset button... and waiting a bit: You can see that the tire thresholds have been changed, but the lower limit not yet... It probably will, but I've no idea how long that takes... BR.Sami

I also failed to the connect to the TPMS ECU with my TechStream, so no screenshot yet... I need to investigate that more. But good to hear that the warning light has gone! So, probably there is something wrong with the initialization procedure: it should set the thresholds lower than the current pressures on the tires... BR.Sami

Hi Kev, I've no idea what that separate low pressure threshold is... but have you tried to fill the tires to e.g. 42psi? Will the warning light disappear? I will take a screenshot from my car for comparison... BR.Sami

Hi Kev, Did you drive a bit after pressing the initialization button? I've noticed that it takes time/miles after the initialization is completed... Could can also see the ID of the sensor reporting low pressure (error code) using the TechStream: is it the new aftermarket sensor? BR.Sami

Remember also the official Lexus repair information at https://www.lexus-tech.eu/default.aspx . It costs only about £3 per hour, but already in one hour you can save lots of information to to your PC... BR.Sami

Forgot to send the final picture (showing the temp sensor + gas extraction tube)... here you go. (and no, there is no need to register new battery to the car as far as I know... I have not seen such option in the TechStream either...)

Update: so rebuild + Tanabe Medallion was my choice. Hardest part was taking the midpipe off: I don't have a lift in my garage, so I had to use jack stands. Working on rusted bolts under any car is painful... and boy those bolts were stuck! Here is a closeup of the holes: you can see the shape of the heat/stone shield edges there: There is some sort of fibre matt between the shields and the pipes: over the time it has maybe flatten and the edges of the shield have started to eat up the pipe... otherwise the mid pipe was actually in good condition still. So, a bit welding and grinding and spraying, and the mid pipe was fixed: I replaced the old fibre matt with exhaust wrap and reinstalled the shields: ...and installed the new cat-back from Tanabe: Project completed! BR.Sami

Yeah, just got the offer from local Lexus dealer: 2500€ for mid pipe (incl. installation). So, I'm open for all options... I'll consider that "rebuild" option, thanx for this hint! BR.Sami

Hi all, I found out that there is a hole in the exhaust pipe just after the lambda sensor... I have fixed one hole earlier, so I think it is time for renewing the whole exhaust system (or at least mid pipe and the rear section). Based on the topics on this forum, the best solution seems to be Tony Banks. But, that is not feasible option for me, as I'm located in Finland... I've tried to search for parts, but it seems to be very hard to find anything. I was able to find Revel (Tanabe), but that is only the cat-back. Invidia has both mid pipe and cat-back for RWD GS350, which I assume to be compatible with GS450h (right?). But those are in U.S. Any pointers to european shops which would have parts for GS? BR.Sami

Hi, Just wanted to share my findings: I was looking for new 12V battery for my GS450h (2008), and these will fit directly the battery tray in the trunk: Varta Blue Dynamic E23 570412063 70Ah 630A size (in mm): 261x175x220 BOSCH S4 026 70Ah 630A, size (in mm): 261x175x220 Yuasa YBX3030 12V 72Ah 630A SMF Battery, size (in mm): 260x174x225 The original battery is Lexus 28800-31281 Panasonic S65D26L 57Ah 450A, size (in mm): 260x173x202. I ended up buying the Yuasa YBX3030. Installation was really easy: the only thing you need to do is to remove the temperature sensor from OEM battery and glue/tape it on top of the new battery. Picture of the temperature sensor on OEM battery: BR.Sami

Hi, You don't need to change the tyres, just bring them close to the car... Then open Techstream's TPMS Live Data monitoring and check if you are getting any readings... Then you can e.g. move away the other wheels one by one and learn their IDs while monitoring the Techstream 😉 If I remember correctly, the IDs are changing in the Techscream display if you press that tire selector switch. It only displays 5 IDs at time. If you have the warning symbol + text "Check system" on the small screen, that means the ECU cannot read one (or several) of the sensors. There will be error codes visible on Techscream as well. The "Low tire" indicates that communication is ok, but you need to check the pressures + so the initialization procedure. I've visited two local tire shops here in Finland, and both of those had that kind of a general handheld scanner: they just selected first the make & model of my car and started scanning... One word of warning: I had a lot of trouble with one set of aftermarket sensors: they worked most of the time, but not all the time. Had to switch back to the OEM sensors (after battery change). I hope you have reliable sensors... BR.Sami

Sorry for stubid question, but did you switch to the second set of sensors by pressing the button under the glovebox? Your pictures were a bit blurry, but it seems that you have errors from 5 different sensors? The only way to know if the sensors are ok (e.g. sending something) is to go to a local tire shop: they should have a handheld scanner which can read the sensors through the tire... and they should be then able to tell the correct IDs as well. Note: the initialization procedure only sets the pressure limits for sensons, first you need to have working sensors the ECU can read... BR.Sami

I've been missing proper DRLs for my GS450h... mainly because here in Finland, we need to use some headlights even in day time. And the AUTO option of GS will switch all lights off if it is bright enough... So, I installed Osram Led DRL+Fog lights to replace the original fog lights. https://www.osram.com/ecat/LEDriving FOG-LED fog lights-Cars-Automotive Lighting/com/en/GPS01_1074552/PP_EUROPE_Europe_eCat/ZMP_1188268/ I first disassembled the original fog light housings, then manufactured custom brackets from aluminium. Here is couple of pictures of the process & end result: Old parts: New parts: End result: Have to say I'm really happy with the end result! 😉 BR. Sami

Hi, Not easily: the valve stem is permanently attached to the sensor. you need to cut it, if you want to replace it... and then attaching a new one is difficult. I've done this to one set of sensors, which were so stuck that I had to drill them to get them out. I used just some generic repair kit (like https://www.autodoc.co.uk/schrader/14528270) and lots of epoxy... BR.Sami

I can confirm this. They bolt directly to the shell... I've not noticed any difference on the road noise. Very silent car (except when the rear bearing was gone) BR.Sami
