Welcome to the ES club @atticus

Fine choice and you will also appreciate the great mpg. Currently I get around the 48 mpg mark.

Hi,

Coming from the ES forum section as there was another member who's ES300h was stolen using the same CAN Bus method.
I see @eightk has already mentioned the link to the article of how the CAN bus injection method was done. 

It looks complicated, but the overall structure is quite simple compared with the large amounts of wires in the old days.

The Controller Area Network (CAN bus) is the nervous system, enabling communication.

The 'electronic control units' (ECUs) are like parts of the body, interconnected via the CAN bus. Information sensed by one part can be shared with another. The CAN bus system enables each ECU to communicate with all other ECUs - without complex dedicated wiring. An ECU can broadcast information (e.g. sensor data) via the CAN bus, consisting of two wires, CAN low (L) and CAN high (H). The broadcasted data is accepted by all other ECUs on the CAN network - and each ECU can then check the data and decide whether to receive or ignore it.

Looking at the device in the article. It seems the way these thefts are taking place is by accessing the CAN H wire and using a P-Channel FET device to send the signals necessary to confuse the system and gain access into the vehicle.

In software similar to SQL injection attacks, networking Denial of Service (overloading a network node by rapid requests) and this CAN bus attack has elements of both.

This issue has been noted to the The National Institute of Standards and Technology (NIST) in the US and this vulnerability is listed here. Toyota is aware of this but don't expect any quick solution as it requires a mass software updating of the the current and earlier models for a software fix, which would cost Toyota in the millions and not something they would want to undertake.

Thank you for that link .

fascinating . A very detailed analysis of the car systems. Very complicated to understand though .

Sorry to hear about the theft. I have an ES too and looking to build a CAN bus fix. 

The below article gives a very good understanding of how CAN injection works.

Hi all,

Recently did a road trip to Royal Tunbridge Wells and did a test on the different drive modes and saw some amazing mpg results. 

I normally get around 47.8 mpg driving in normal mode. So before setting off after refueling, I reset the mpg and set off and drove only in sports mode at 60-70 mph and after the journey it showed 48 mpg. 

Which is impressive. The power response is much better in sports mode. 

I was expecting to see a lower mpg but it seems it stayed around the same mark when I drive in normal mode. 

Nice review Nick. I myself share the same views and have a white ES F Sport Takumi. 
I have got used to the the length now. And can not miss it in a parking lot due the long nose sticking out like a baby shark with that smiling grill. 
I have also learnt to play around the power bands to get the best torque and power the system has to offer. 

I call my one, baby shark. As the snout sticks out quite a bit in the parking bays. 
Just need to look out for a big smiling grill when I look out for her. 
Have to say the parking bays are getting smaller these days.

I do not believe it is possible on the ES Slucky.

Thanks John, shame as its got quite a decent size boot. 
Now I can't load me timber around in style.

Agree with you, as I came from an IS 300H too and since driving around my ES, its so much better.

One thing I can't seem to find in the manuals is how do you fold the back seats, or is this not possible?

Thanks

Thanks Colin. 

Hi all,

anyone know what the menu function Powertrain and Chassis do? and is it the same function as the drive mode selector stalk.

Someone else who has gone from an IS300h F Sport to ES300h F Sport 👍 I hope you'll enjoy yours as much as I'm enjoying mine.

As much as I loved my IS, it was a change that was going to happen inevitably. 

The ES is different and not in a bad way. It is way over the IS in terms of quality. And I had the top spec IS as well.  

Hi Paul,

I recently got the F Sport Takumi from my previous IS F Sport.

By take on the ES:

• Tahara seats, they are soft and comfortable, much better quality than my IS
• Ground clearance seems slightly higher compared with the IS
• Ride quality on 19 inch wheels is smooth, and not jarring. You can feel the road without it being too intrusive. Tyres all on bridgestone.

What made you pick red seats?

The F Sport only has 2 options black or red. My IS was black interior, so went for red this time. 

Yes I think the engine torque which is available @ 3,600 compared with the IS @ 4,200 helps too.

Hi All,

Have recently bid farewell to my lovely IS 300H F Sport and now a proud owner of an ES F Sport Takumi in white.

Overall happy to the car.

So this week, I bid farewell to my lovely, looked after IS 300H F sport in sonic titanium and now a proud owner of an ES 300H F sport Takumi

Have noticed a few differences.

• Brakes are much better on the ES
• Throttle response and speed much quicker then IS
• It is larger but very spacious inside.
• The 12 inch multimedia display is something.

Overall very happy.

Thanks @Spock66 would you know how these philips are:

Thanks for the information @Herbie that is good to know.

Didn't realise that this would be an MOT Fail. 

Oh well, looks like have to look into some better HID bulbs.

Hi All,

Has anyone on here converted the stock D4S HID Bulb to a D4S LED bulb. 

I ask as I'm looking to change my less bright HID to LED ones on MY13 IS300H. The current light reach is quite poor, having replaced a failed bulb from Lexus last year.

Was looking to upgrade to the newer IS300H with LED lights, but seeing the current used prices, it does not seem worth paying thousands extra.

So thought it might be much cheaper to convert the headlights to LED.

Have seen some on amazon - https://www.amazon.co.uk/Headlight-Bulbs-Conversion-10000LM-Replacement/dp/B08BYJWDDQ

Any ideas on how difficult or cost to have this conversion.

Thanks

I have had the same issue, my USB ports were working fine, was using one to connect my Iphone and the other had MP3 files on a USB stick.

Then one day, both USB ports stopped working and showed grey on the display, tried everything, and even went to Lexus for a check-up at a cost of £125. 

Lexus workshop said it was a faulty USB port and quoted £560 to replace the USB ports.

Bought one a genuine spare from eBay for a much less price, and replaced it.

Are you using the USB port to connect a phone or connecting a MP3 usb stick?

I have used a 128GB USB drive, that was formatted to FAT32 to play music on my IS 300H, with no problems.

Used my MacBook to format to FAT32.

Having said that, lately both my USB ports do not function. Does not recognise my USB Drive or my Iphone which is connected to via USB. It used to work fine, but has stopped working completely. 

So took the car to the Lexus workshop and they have now quoted me £580 to replace the entire USB unit as, there was some fault.

Anyone experience this before, and any other options for a cheaper fix.

Hi All,

Any help appreciated. 

Recently both my 2 USB and AUX ports in the arm rest stopped working on my 2013 Lexus IS 300h. It was working fine last week, but now no reaction when I connect my Iphone. 

I have noticed there is some sort of white power around the arm rest latch, don't have a clue what that is.  

There has not been any water leaks around the area. 

Saw somewhere on the forum about a capacitor leaking!

Any help would be appreciated. 

Thanks 

Thanks, On checking the correct mpg is around 47 and yes the on board computer is about 2 digits higher.
