  1. Indeed. They have been removing incentives over the last few years.
  2. There are some elbow connectors and joints, no description of a valve in the parts catalogue that I can see. Possibly it isn't a valve and just a blocked connector? Otherwise I imagine it would be a one way valve to stop the fluid draining back so it always squirts first time.
  3. Bus is a computing term meaning a shared communication path between components, essentially via copper wires either within a system or allowing multiple systems to communicate with each other. CAN is an acronym for controller area network (hence why it is written in capital letters) - it is the specific protocol, or language, that is sent over the bus - like humans, two items communicating need a common language to understand each other. Within the auto industry there are many different protocols used. Toyota/Lexus commonly use CAN, LIN, AVC-LAN and MOST. The reason for using buses rather than discrete wiring is to save cost and allow more sophisticated features. Take the rear light clusters, (Toyota don't typically use CAN for rear lights but just as an example) - traditionally you have multiple wires, one for each function: rear light, brake, left indicator, right indicator, reverse and fog. That's 6 controls wires + ground. If you had sequential indicators you need two more wires for sequential mode rather than standard on/off required for hazard, so a total of 9 wires. If you had CAN controlled light clusters you can reduce to just 4 - +12v, ground and two CAN wires. If you want your mirrors to drop when in reverse, rather than a signal wire going to the mirror ECU, it can just listen for the reverse communication without needing any additional wires. If you take it to the extreme, where modern matrix headlights are made up of 1,000+ individual LEDs that each can be controlled individually to block out the beam to oncoming traffic then that wouldn't be economically possible or reliable using discrete wiring.
  4. This is why our insurance premiums are going through the roof. Everyone from manufacturers, body shops, hire companies and dealerships all making easy money from insurance work.
  5. There are several YouTube videos of Lexus being stolen from Ring type camera footage. Some are off driveways and others from the street outside the house. There are a couple where they have been stolen with a disklok fitted where they just use a battery angle grinder to remove it.
  6. I'm in the UK, I just don't want to advertise where on the internet and the forum software doesn't just give a generic UK option. CC2 are fine all year round in the UK, plenty of members here have them. Actually I'd say it is the perfect country to run them, especially if you aren't in the south (where you can realistically get away with summer tyres all year round if you are careful). Most northern European countries have harsher winters than we do, where they really need proper winter tyres for part of the year. I was happy to have UHP on my GS F, not necessary on my previous IS300h F Sport. You certainly need to retain the standard controls - I think most will support that. You need to make sure whatever unit you are interested in supports then infotainment system you have as there are a couple of different options. I'm not so sure. Many people take the cheap Chinese products and repackage them and sell for a higher price - they might provide helpful installation advise but if they have no control over the firmware/software then you are stuck with bugs until the OEM issues an update, if they ever do. Hopefully other members here who have done this will be able to offer some advice. I've never do it, I just used a phone cradle and my smartphone for improved navigation and access to music etc.
  7. Pin 3 on the fog light connector is for cornering lights, which is controlled via the headlight ECU. I don't know if it would be as simple as removing that pin from the connector and putting insulation table around it. Some duct tape over that element of the fog light lens would be the simplest solution.
  8. Not sure you would need to replace the LCAs on a 2020 vehicle. Air intake is high, at the bonnet level, but not sure if the resonator is air/water tight that sits lower so I wouldn't be submerging the vehicle in any deep water. CC2 tyres are a good choice. Not the ultimate in performance or economy but suit the IS300h quite well and give good grip all year round. Carista is a good way to change the vehicle customisations that aren't available through the in-car menus. It can be expensive to subscribe long term but most people would only need one month's access and then don't touch it again. If you look in the owners manual at the customisations there are a bunch of options that are dealer configurable only - these you will be able to alter with Carista - e.g. how many indicator flashes on a light press of the stalk, how long the headlight stay on after you exit the car etc. Standard infotainment is a bit rubbish. Many of the Android based third party options have good features but are flakey in operation. Aftermarket air filters - directly OEM replacements are ok to save a couple of ££, although may not filter as well. So called performance ones are a complete waste of money on the IS300h unless you go for a complete induction kit - and even then the gains would be minimal at best.
  9. The fuel filter is attached to the pump in the fuel tank. It isn’t changed regularly as part of a service but clearly if you have a fuel delivery issue then the filter and pump should be inspected.
  10. The alternator has a clutch, it is enabled/disabled as required. I suspect when it is enabled there is extra load on the engine which pulls the rpm down and then the idle is adjusted to compensate. I don't think it should be that severe, and I wouldn't expect the battery light to come on at all - Lexus state that would only happen if the clutch or alternator have issues. Did you get a new clutch with your alternator, or did you swap that over?
  11. It sounds like the alternator isn't outputting enough at low speed and as a result has killed your old battery. Not sure on the plug you are referring to on the alternator, will see if I can find some info.
  12. The recommendation seems to be Toyota's standard procedure when the battery is in the engine bay - ideally you don't want to connect to the -ve on the battery (which will cause a spark) in case there is hydrogen gas present so they suggest a remote connection. This precaution makes no sense when the battery is located in the boot and your jump points are in the engine bay. Any good earth point can be used.
  13. Are you saying the valve clearances closed up? I don't see how that is possible, wear can only cause the gap to increase between the cam lobe and follower/shim - unless something happened to the VVTi/timing.
  14. The message is documented in the manual: If “Regenerative Braking Limited Press Brake to Decelerate” is displayed Regenerative braking may be restricted in the following situations. Firmly depress the brake pedal to decelerate the vehicle. ● When electrical energy cannot be regen- erated any more as the traction battery is fully charged ● When the temperature of the traction battery is extremely high or extremely low ● When the temperature of the electric motor or power control unit, etc. is extremely high It makes sense when the battery is full, and near full as the charing current has to be reduced, but at 80-95% that doesn't really make sense. I'd contact your dealer to log the issue and see if there is a software update to improve this.
  15. Yes, certainly worth familiarising yourself in ideal conditions where the jump point is before you actually need it.
  16. Yes of course, apologies. Using the jump points in the engine bay means you don’t have to get the boot open if the battery is located there.
  17. Partially. Many older Lexus models are like this too, the series II GS for example. Newer vehicles, like the ES, are definitely improved in this area, although the materials themselves may not be as nice as they once were.
  18. What company? Any change in excess / benefits?
  19. It's an error that can come up on either version but I certainly wouldn't expect to see it at 90%, possibly at 100% for a short while.
  20. 1 - Yes 2 - Don't. To 'jump' the vehicle, connect your battery pack directly to the battery once you open the bonnet.
  21. Yes you are probably correct - I know there are errors/contradictions in the press material and brochure. Either way, specs can vary greatly between countries so it doesn't mean it is a standard feature for Charley (I'm assuming he isn't in the UK as the ES 350 isn't sold here).
  22. If you get one from Lexus they will supply the most current part if you give them a superseded part code. I'd assume that the battery wouldn't be that old as I'm sure they sell quite a few so it's unlikely to have sat on the shelf for years. The current generation of sensors have a deep sleep mode from manufacture - only when they detect a certain pressure do they come alive for the first time - I imagine the ones back in the 2000s operated the same way.
  23. In the UK the ES 300h F Sport and Takumi grades have active noise cancelling. I assume this functionality is available as standard or an added extra on some of the grades offered in your country on the ES 350? Typically the larger the diameter of the wheel the more noise is transferred to the cabin so consider grades will smaller wheels. Certainly worth test driving the options available if you can.
  24. Hi Peter. You can access wiring diagrams here: https://www.lexus-tech.eu/euro5search/index?PUBTYPE=EWD You will be asked to register, which is free, but to access the diagrams you have to paid for timed access. It is €4 per hour for short term access, which is all you will need. This is for European vehicles - I doubt there is much difference to the wiring between regions (a benefit of using CAN is you minimise wiring and can software control regulations between regions) but if Lexus offer a similar service in Australia you would be better to access local information. It isn't going to tell you much however, other than pins 23 (white wire) and 24 (black wire) on the headlight ECU are the CANL and CANH signal pins. A CAN message is sent to turn on/off high beam, so you need something that will read the CAN bus and look for the correct message - the decode of the CAN messages isn't detailed in Lexus repair manuals so you will have to figure that out - monitor the bus and look for the messages as you enable/disable high beam.
  25. What happened? The areas of investigation for too rich are on the right of the table below, in order of likelihood - however for both banks to be affected, I wouldn't suspect an injector or A/F sensor as they are bank specific and you wouldn't normally get multiple failures at once. P0172 P0175 With warm engine and stable air-fuel ratio feedback, fuel trim considerably in error to rich side (2 trip detection logic) Injector leakage or blockage MAF meter ECT sensor Ignition system Fuel pressure Gas leakage from exhaust system Open or short in A/F sensor (bank 1, 2 sensor 1) circuit A/F sensor (bank 1, 2 sensor 1) A/F sensor heater (bank 1, 2 sensor 1) A/F HTR relay A/F sensor heater and A/F HTR relay circuits ECM
