  1. I do not see why not. I cannot the LS600 being any different to the Lexus cars with TPMS. John.
  2. Not quite as easy as that. The battery is potted in a compound inside the plastic case. It is also soldered into the printed circuit by tags welded to the battery. The batteries are the size of a watch, but can be bought for as little as 50 pence each "non tagged". With reasonable care the batteries can be replaced, and is worthwhile doing in my opinion. By far the most simple way of doing this is to have the valve/monitor removed, and replaced with a standard rubber valve by your local friendly tyre depot leaving you free to fit a new battery at your leisure. Once this is done the valve/monitor can be refitted. John.
  3. I also use the cheap bulbs, and find no difference in light output or longevity. I figure I can buy 10 of these for the price of one Lexus/Phillips bulbs, and would still be worthwhile if they only lasted 1 year. Also no problems with the MOT with the cheap bulbs fitted. John. I no what you mean about having small hands "I do not", but with patience, a light, and a small mirror the job is doable. John.
  4. Try loading the files from the disc to a memory card or stick on your PC then use that on your laptop. John.
  5. Hi Andy. Sorry for the late response. From memory to see the battery condition in Techstream you have to select one of the keys on the lefthand edge of the screen. I think it is marked "data". Further from what I can gather depending on the version of the software you have it will give you the actual voltage or a description from translated Japanese. I cannot remember the actual words but it was not high or low, or full, and empty, but you will understand the wording. When I get chance I will connect up to the car, and give more precise details. John.
  6. Hi Jeff. Sorry to answer with a rather long post, but it may give you an answer, and an incite to battery charging. The charger you have is the old school resistance charger. It uses a transformer to bring down the mains voltage, and a rectifier to change the AC supply to DC for charging. It then uses a wire wound resistor as a current regulator. Effectively the resistor drops the voltage depending on the amount of current being drawn "the higher the current the greater the voltage drop". At the start of charging the battery voltage will be low compared with the charger, and the current will be high so the resistor drops the voltage because it is carrying a high current. As the battery charges it's voltage goes up towards the voltage maximum output voltage of the charger the current being drawn falls, and the voltage drop of the resistor decreases raising the output voltage to maintain the current. This is called constant current charging. The problem with this system is it tends to overcharge batteries if left on charge for too long a period. I would stop the charging when the 100% light is on with the others turned off. Modern chargers use a program usually to give three different charging rates:- A high voltage to give a high current charge to charge the battery to around 80% to 90%. This is called bulk charging. At around this level the battery begins to refuse to accept charging, and starts to heat up. The next stage takes over charging the battery at a steady lower rate until the battery reaches it's full voltage. This is a voltage "for a 12 volt battery" of 13.8 volts up to 14.2 volts depending on the type of battery. Flooded "standard car battery", AGM "absorbed glass mat", and AGM gel "an AGM battery with a jelly instead of a liquid electrolyte". At full voltage the battery charge voltage is bought to a level where the battery is being charged at a few milliamps. This is called float charging, and can usually be kept up indefinitely. A flooded battery will be fully charged at 13.8 to 14 volts An AGM battery will be fully charged at 14.2 to 14.4 volts An AGM gel battery will be fully charged at 14.2 to 14.4, but it's charge rate must be kept at or below that of the manufacturers specification. The charge rate is limited because the battery must not be allowed to gas. This is because the gel will hold the gas as a bubble against the plates of the battery reducing the area of contact of the gel electrolyte to the plates. In a liquid battery the gas would simply float to the surface. In a gel battery a gas bubble is almost impossible to remove reducing the capacity of the battery. John.
  7. I notice that the OP has an LS400 that has the normal torque converter type transmission. While I agree that I see no reason to use other non Toyota fluids in his transmission it is perhaps for those of us that have hybrids more important to stay with OEM fluid. This is not because of any special requirement lubrication wise, but because of the very real need for the lubricant to have good electrical insulation properties as the oil is used to directly cool the winding's of the HV electric motor/generators. John.
  8. Matt thank you that is interesting, and something I will look at. It may be the particular version of the software that is giving this anomaly. I have two versions, but the version I am running I have been using for around 6 years. I did not have reason to update it since it was working perfectly with both my Lexus and my wife's MMT Toyota Aygo that requires the gear selection, and clutch position resetting from time to time.The second version I purchased about 3 months ago with a new VCI for use on my Windows10 64 bit laptop. I have not tried it yet on my car. I did try the new VCI on my my old XP version laptop, and this did not work, but I think that is because the drivers are not compatible for the new VCI. The VCI was not recognised. When I get chance I will try with my Windows 10 machine to see if it makes any difference. John.
  9. Perhaps the term that should be used for report on the batteries in Techstreem is "battery condition" it does not show actual voltage, but uses words that at the moment I cannot recall. It does not use terms like good, full, low or empty, but there is a Japanese to English translation that gives an idea of the level of charge in each battery or should I say cell. John.
  10. The front wheels turning when stationary with the brakes on while turning the steering was my thoughts, but unfortunately I did not convey that in my post. There was some problems if I remember correctly with the Prius steering UJ that was dealt with in a service bulletin, but I do not know if it also applied to the CT. John.
  11. Hi Ricky welcome to LOC. Are the disks on your car rusty or have areas of shiny brown deposits? The CT, and the Prius from which it is derived mostly use regen braking, and this means they tend to suffer with the disks rusting through lack of use. This gives the low speed roughness you are experiencing. If it is not to far advanced it can be cleared by braking a number of time from around 50mph "down hill preferably" in neutral. In neutral the the hydraulic brakes are forced into use, and this will help clear the rust. Doing this say once or twice a month will keep the brake clean. If the disks are too rusty the only remedy is to replace them. John.
  12. The TPMS not working is not an mot failure for a 2005 car. TPMS is only required to be in working order on vehicles after 2014 for the MOT. Vehicles must be fitted with TPMS if built in 2012 on. John.
  13. This type of sounder is ideal for increasing the indicator sound level. Two can be wired into the indicator circuits "one for each side", and will fit int the steering column housing. John.
  14. The GS450H does not have an EV switch so it cannot be forced into EV. If the HV battery is very high on charge the car will run on electricity up to 70 mph. Under normal levels of charge "5 blue bars to 6 green on the display" it will run in EV up to 30 mph at which point it starts the engine. Your RX may be different. John.
  15. Have you had the rear wheels checked for balance. I lost some wieghts on a rear wheel after hitting a deep puddle on the near side at speed. I then noticed a slight vibration at 70 + mph. Re-balancing that wheel cured the problem. I run my GS at 40 psi although I think 35 psi is the recommended. However I do find the shoulders of the tyres tend to ware at the correct setting, and this is alleviated at the higher pressure. It does not seem to affect ride comfort at that level. John.
