  1. 12V battery is charged if the car shows "READY". charging is done from inverter and the high voltage battery. if the voltage from the 12V battery is below 10,5V it will not be powering up the computer systems and you will not see the "Ready". if the ignition switch is in "radio" or "drive" position depending on what is switched on (lights, radio, air condition, ect.) there will be between 10 and 40 amps drawn from the 12V battery and depending on the charge condition battery voltage will fall under 10,5 volts in 10 to 45 minutes (battery has a capacity of 45Ah and is very small for this car). and yes, in many cases it is helping to switch all and every thing off (lights, radio, air condition, seat heating.....) and take off the ignition key and wait for some minutes (5 to 20 minutes is normally enough) and try to start again. very often ready is then coming up because the starting up is not taking many current (there is no engine cranking like in other cars).
  2. I have an 06 RX400h and the fuse to pull is the Radio1 fuse. It is in the square fuse box under the hood on the driver side. european version of nav DVD (oktober 2008) allows all inputs to the nav system while the car is moving. so with this DVD's override is not longer needed. hope this is the same with US version DVD's.
  3. in europe we had three, china had some. the recalls started in china and please note that this problem is affecting IS and GS as well, but see yourself here Toyota to highway administration
  4. remember our discussions about the first thred here!? if your car was manufactured between 04/03/2005 and 06/10/2006 expect a recall to replace the power steering of your car. here is the customer satisfaction campaign for europe power steering replacement
  5. first, can you check the voltage at battery? how much do you read there? when you turn the ignition key what happens exactly? is the radio coming up? is the interior light coming up? if your car has the standard wiring, a battery shortage will not burn any fuse because there is none at the battery. but of course other electrical malfunctions or shortages will burn the fuse responsible for the malfunctioning electrical equipment. ps.: if you like you can place your questions also at the european lexus owners club forum (german or UK)
  6. look at this! now we come closer New RX
  7. OK, Now that starts to make a little sense. I have a (highly) modified 94 Mazda Miata with a supercharger that I installed and am quite aware of the value of the boost gauge. Come to think about it if I stomp on the RX400h the power meter does seem to respond in much the same way as the boost gauge I installed on the Miata does. This tells me that the electric motors may be contributing quite a bit of power/torque under heavy acceleration. It certianly feels that way. Unfortunately the owners manual doesn't help you to understand that. /Steve if you like to see some more information like engine revs. engine temp, charging voltage (for the 12V System), exact speed of car.... and some more you can use the SCANGAGE II. it works great in the RX400h. have a look here Scangage II
  8. we did something very similar with the RX400h and used a 35W halogen lamp. result was a melted lamp socked, a blown fuse and a malfunctioning head unit. It seems improbable, impossible really, that a 35W halogen, even two, would be left on long enough (backup lights...??) to melt the socket, blow the fuse, or cause a malfunctioning "head" unit. My '01 RX300 has the same arrangement and has NEVER blown the fuse. What "head" unit do you speak of? Fact is the following: On our first try to improve the reversing lights on the RX400h we used stronger bulbs/lamps, in my case 35W halogens, fitting into the standard lamp sockets. After 2 weeks the back up camera and the navigation system went out of function. Lexus dealer/service found a blown fuse controlling some equipment in the trunk including the reversing lights. When the technician took out the reversing lights/sockets, the sockets had been crumbled and black and caused a shortage. So what I am saying is, if you upgrade the lamps “be careful and make sure that the lamp sockets not getting to hot”. And we found a much easier way of improving the reversing lights by taking out this funny lamp cover forcing the light going up instead of illuminating the street behind the car. So......, I'm guessing here......... You had a relatively poor, high resistance, connection for the 35W halogen where it was plugged into the socket.... In the process of the dealer troubleshooting the backup camera problem the backup lights were left on for an extremely L...o......n...........g time. I'm surprised the service technian didn't smell something burning and go to the source sooner... sorry, wrong guessing! there was high contact pressure, but we used the original sockets. you are using (at least it looks like so on the pictures) special halogen high temp sockets mounted somehow on the original sockets. during the lexus technician troubleshooting process, the reversing light had not been on, because the fuse for the reversing lights was already blown from the melted sockets and the blown fuse caused the malfunctions on the head unit. but please don't get me wrong here! i am not saying what you are doing is wrong, no. but it should be done with special care and it is not as simple as it looks! as you named it, resistance between lamp and socked, lamp heat, burning time...... and remember resistance between lamp and socked may change over time, contact pressure becomes weaker and socked temp gets higher.....

  11. yes nice but.... lexus UK came up with this: I heard back from Lexus today. The Lexus quality engineers tested the Black and Decker mentioned before, and their verdict is that it is NOT APPROPRIATE as its output is too high. They haev no further suggestions at the moment, but the case is still open and they "are working on it". I am off on a three week trip tomorrow - maybe it'll start on my return - fingers crossed.

If they DO finally advise it, I think we should all get a free one. As mentioned previously, they eventually replaced my 12V battery a couple of months ago. I returned yesterday after 21 days abroad, and the car which had been standing outside, started with no problem. Perhaps I had had a dud battery all the time. I am still worried about leaving the car for a longer period - will have another chance to test it on my next longer vacation. When I hear from Lexus about the Black & Decker I will share this information. Ruth
  12. this should help! Removing_bulb_cover_from_reverseing__light.pdf
  13. Hi all! Let me suggest that we all stop guessing around here. Fact is that the incident happened and it is verified by a lexus dealer. The german lexus user forum is waiting for a statement from lexus. rgray is right, the mechanical steering was not turning in the opposite direction but the car was moving not in the direction his driver wanted. Again let’s wait for some official response and more facts.
  14. yes this is a well known problem! look into your reversing lights. if there is this silver bulb cover mounted inside than you can easily increase the brightness of your reversing lights by taking this cover out (can easily be done, it is only screwed in place, i can send you an instruction to remove it). it is mounted on the wrong side of the bulb so the light beam is looking up and the street behind your car is not illuminated.
  15. you can also use a Black&Decker BDV040 booster sold in the US as model BB7B. this saves the isolator diodes and you can easily check the booster's charging condition. Black&Decker Battery Booster BB7B it fits perfectly in front of the middle console and is fixed by moving the middle console to the most forward position. If necessary the unit can be charged while driving by pressing the charge button. The led's show the charging condition. If the RX400h's 12V battery is having less then 10V the power up sequence (starting) is not longer possible. In this case you bring the ignition key to the radio position (in this position all 12V plugs are connected to the 12V system), make sure that all 12V devices are switched off, B&D BDV040 (BB7B) is connected to the 12V plug, switch the B&D on and press the vehicle boost button. The voltage comes up to about 11,9V. Wait for 2-4 minutes and then turn the ignition key to the starting position and READY comes up.
