The facelift moved TPMS initialisation to an electronic setting via the instrument cluster rather than a physical button as on the pre-facelift series IV.

Looks like the factory did offer another red (3S0) but wasn't available as an option in this country to my knowledge:

Yes, it is active in all modes. Below is for the NX but it's the same for any Lexus with AVS - it is always active. The AVS damping force control system consists of controls performed according to driving operations (vehicle speed sensing control, anti-dive control, anti-squat control and roll posture control) and controls performed according to road conditions( repercussion control/sprung speed proportional control, roughness sensing control and unsprung damping control). The AVS system optimally controls the damping force through cooperative control together with the brake control system and pre-collision system. A mode switching function is provided, which makes it possible to select the damping force control mode by performing drive mode select operations.

looks much more usable compared to the UX 👍

Just a shame that some dealers ‘forget’ this and pocket the money instead.

Welcome Jag The series III RX (2009-2015/16) doesn't have the CAN bus vulnerability, only the series IV (2016-2022/3) is vulnerable. See here for detailed info on the spec of the various different grades (Premier is the top grade):

Correct.

I guess someone could mistake Sonic for Mesa Red (3R1) if you didn't have two cars side by side to compare - Mesa Red is a 3 stage paint available on several Lexus models, but not the LC. Best to try and get the paint code if you are unsure. Names are commonly wrong because Lexus use a different name for the same colour in many different countries, and then Toyota do the same. So you may find 10+ names all for the same colour which can be confusing.

Sorry, 1800 not 1200 - I followed the link in the Youtube posting

Electric SUV of the year apparently https://media.lexus.co.uk/lexus-rz-450e-named-suv-electric-car-of-the-year/

Not sure when they officially stopped taking orders - Lexus don't really make announcements when they discontinue a model, only when they introduce one - the replacement 200t was orderable from September 2015. There were definitely IS 250s registered up until that time - probably long after the order book was closed because of pre-existing orders yet to be delivered, showroom vehicles yet to be sold etc.

As above from Tickedon, UWB is a wireless technology that is used in this instance for the vehicle to more accurately determine how near a key fob is to the vehicle using Time of Flight calculations - therefore if your key is 'relayed' from your home to the vehicle it will know and won't unlock. It also potentially allows a UWB capable phone to be used as a key fob. I'm 99% sure the LBX will use authentication on the CAN bus, the same as the Yaris Cross, and therefore isn't susceptible to the common attack we see on the ES and RX but Toyota haven't officially confirmed this.

The 200t was discontinued in the UK during 2017 and it wasn't really selling so we are literally only talking about 20 IS200t vehicles that are vulnerable to a CAN bus headlight attack.

UK. Here are the sales figures for the series III IS - second row, the top one is for the CT https://media.lexus.co.uk/wp-content/uploads/sites/3/pdf/Lexus-UK-Sales-Figures-December-End-of-year-2023.pdf

Possibly your 12v battery is discharged and nothing to do with the immobiliser. Either way I would get Lexus to look at it under warranty.

Yes. The facelift model introduced LED headlights which are CAN bus connected. Basically any IS built (not registered) from October 2016 until it stopped being sold here in 2020/21 - there were around 5,000 sold.

Just the latter point. All the targeted Toyota/Lexus vehicles also have the pre / primary / main cats in the engine bay - it is Toyota's standard design.

Nothing official but it does seem that devices on the CAN bus need to be registered/signed to stop unauthorised devices being allowed to control systems on the latest NX, and most new models since 2021. This is essentially based on the fact that openpilot doesn't work and there is an advanced repair procedure for replacing items. https://github.com/commaai/openpilot/wiki/Toyota-Lexus#2021-toyota-ecu-security-key-support-new-steering_lka--more

Potentially vulnerable models are ones with CAN bus connectivity into the headlight which includes: NX RX series IV ES IS facelift (10/2016 on) RC F RC any with triple headlights, all from 10/2018 UX LC LS GS facelift (10/2015 on) GS F Whether they are a target would come down to how accessible the headlight wiring is from the wheel arch and the market for the vehicle/parts. Something like a GS F is going to be difficult to offload without it being noticed and there would be a very limited market for parts. Potentially there is also nuance between the models so the attacking tool doesn't work on all vehicles (yet). Based on info posted by our members here, it seems NX, RX, ES and LC are vulnerable to this attack.

Looks like the unit is only €1200, much cheaper than the JLR tools he has.

If you order a screen and headunit directly from Lexus it would be cheaper to sell your vehicle and purchase another UX with the higher specification as you would be looking at a bill for £4k+.

Has it been accidentally turned off via the switch in the glovebox?

I would ask is the engine temperature stable, but I don't think you get a temp. gauge on the CT. Possibly a thermostat issue, or an air lock if you have had your coolant replaced recently.

I'd recommend you never just use Accessory mode when sitting in the vehicle, always put it in Ready mode and let the petrol engine cut in/out as needed. That way the hybrid system is providing the power to the vehicle and charging the 12v battery.

Yes, stupid decision but I suspect it was too big a change for just a facelift and it still suits their primary market, Japan. They really should have fitted European models with CCS as Chademo is dead here. The Japanese manufacturers grouped together to create Chademo, hence why they are trying to cling onto it - but they have virtually all moved to CCS for Europe and Tesla NACS in NA, even Toyota, for new models.
