I had bought an updated disk for my navigation system for my 2003 SC430. After putting it in my navigation system the display shows updating then kept looping for over 25 min. While reverting to the old disk the nav. displayed requested that I insert the updated disk--I did but the looping continues.
View 14 RepliesThe back light on my wife's Nav and climate and radio do not work at night when the lights are on. During the day they work and at night if the lights are off they work. Did a search and could not find similar problems.
View 14 RepliesWell I cracked the clear plastic lens on the AC control unil while removing it to replace the factory radio. Where I can just get the minimal parts to fix this? Seems all I can find online thus far is only replacement of basically the whole control unit.
View 7 RepliesAny way to keep the nav page displayed when on a phone call? I have a 2008 SC 430 with the latest software update. Every time a call comes in, or out, I lose the nav display the duration of the call. makes it hard to navigate while trying to conduct business.
View 4 RepliesI just purchase a 2002 SC430 with only two (minor) issues. First: the radio display does not work. Everything else is fine. The CD changer works, the radio works, the steering column controls work. The display is blank. Lexus solution is 650$ for a new radio. Seems like there should be a simpler fix.
Second, the panel covering the display does not come down. I can pull it down, and it will go back up with the push of the button. But it will not go back down. Again Lexus fix is 700$. I guess I can keep pulling it down for that price, but how was it resolved.
About every 10 to 20 minutes while driving I hear 5 or six intermittent beeps. No warning lights or anything, just the beeps. What is it? I have a 2002 SC430.
View 7 RepliesJust took delivery of my 2005 SC430 (Egyptian Sand, white leather, 55k miles. Lovely vehicle.) which I thought came with Bluetooth.
However, when looking to pair my iPhone 4S the 'Phone' icon is not present on the ML Nav Info display screen, suggesting that maybe Bluetooth is missing? I confirmed it's a 2005 from the VIN.
When I depress the little button below and behind the steering wheel volume buttons (left side - this is a US car) I get a voice saying 'No cassette inserted' or words to that effect, suggesting it's a cassette control button, not a Bluetooth one. The Nav instruction book which came with the car specifically refers to the presence of Bluetooth.
How to find if I have Bluetooth or not? My iPhone cannot 'discover' anything.
Recently, i just bought an multi-information display panel (with touch screen support) to integrate into my RX330 which is a non touch screen NAV display panel.
The 2nd hand multi-information display panel is from a 2004 RX330 and what are the socket behind the display panel meant for.
what is the 4 socket connectors as indicated in the red circle in the image should be connected to?
I purchased my 92 Silverado in Dec. 2008. Since I got it the temperature control display has been blinking 'A/C' for 2 minutes after starting, than goes away. From the owner's manual and the GM service manual I realize this means there is a problem in the A/C system. I figured that it was low on refrigerant since the compressor clutch would never kick on, that and that is what it typically has been in the past with other older vehicles. After buying the retrofit 134a kit, I recovered the stuff that was in it, then proceeded to add the new stuff.
The pressure kept rising but the clutch never engaged. I looked through the GM service manual and they suggested to do the obvious. Is there power to the wires i.e. the cycling switch and the clutch positive wire. There was not. I inserted a jumper on the cycling wires figuring this would complete the circuit telling me if the switch was bad or not. With jumping the cycling switch I still had nothing, the clutch never engaged. My next thought was well maybe the internal clutch relay or the pump was shot. So I ran a jumper from the positive post of the battery, to the positive post on the clutch relay itself. Then the clutch kicked in, I sucked in the 134a and everything was working. I also did this to the cycling switch, when I added power the clutch engaged and all worked.
This tells me I have an electrical issue and the mechanical stuff should work. I don't believe that it would be the cycling switch because with it jumped it should engage the clutch of the compressor and it did not, In fact it did nothing with a jumper on the cycling wires. I assume that I have an issue elsewhere that is causing a dead spot in the system or else the cycling switch would have power to it.
1981 Datsun 280ZX 5spd manual L28 IL6 SOC. maintenance history unknown. Today after a short drive and a bath the engine started looping after 2000 rpm. The car idles fine while sitting but as soon as you push the gas the engine revs to 2k and then decelerates then back up to 2k then back down.The car does this with no hesitation until you take you foot off the gas then idles normal again. Could this be a sensor issue? If so which one? The car didn't start the problem until i bathed the engine area.
View 1 RepliesI have a 96 buick skylark. I just recently had the parking pawl fixed because it was broken. Now when I slow down the engine idle seems to start looping and almost stall, it in fact has once. As I slow down, and I can feel the car somewhat trying to pull forward as if its not down shifting correctly. when I finally get stopped the idle will come back up and idle normally. the car upshifts great. I know that one of my rear wheel speed sensors has a broken wire.

If i get my hands on a used one will I still have to Reflash the ECM or will the car start run and drive plug and play?
New owner of a 2007 and 1st post. My antenna goes all the way up and then one of the sections retreats.
View 8 RepliesThe lexus sc430 is nice but when I floor it , there is a 2-3 second delay until she kicks down and really takes off. Someone said there is actually an adjustment on the transmission to eliminate this delay. Never heard of such a thing.
View 3 RepliesJust bought my sc and the top won't go down,when I press the button nothing happens no blinking lights or noise.if I open the windows and press the close button the Windows go up,but when I press the down button nothing happens.
I have the trunk cover close and I checked all the fuses in the trunk but they all seem fine nothing blown that I can see.i disconnected the battery overnight and still nothing. I also checked in the glove box and the button is pushed in like it is suppose to be.
Is it possible to turn off antenna when CD is on?
View 7 RepliesA few months my AC starting blowing hot air. When I was at the dealer, they claimed the compressor was bad and wanted over a 1000 to replace. I looked online when I was there and said the new denso compressor was about 300 online. They wanted double. I just left and didn't worry about it since it was about winter then. Now I need to get it fixed.
A guy noticed the other day when I cut the AC button on, the clutch engaged and cut back off. He didn't have time to fully check it that day and wants me to bring back if I can another day.
I did some searching on this board, but haven't seen compressor issues with the SC430. I have a 94 ES300 and a 2004 RX330 and neither have had compressor issues. So I am shocked at this anyway.
I bought a relay, but that did not work. I just read on the LS forum that a lot of people have had problems with the AC pressure switch.
I understand that switch could prevent the compressor from coming on when the switch goes bad. Do we have that switch on the 06 SC430? If so, where is it? I can't find a part number listed in All data. I would love to check it before spending a ton of money on compressor replacement.
By the way, I have plenty of refrigerant. They checked that at the dealer and added some then. And I did AC diagnostics and show no codes.
I thought my top used to go down in drive when I was at 0mph, but recently it only goes down when the car is in park. Maybe my memory is just bad but does everyone's sc430 top go down in park only ? Or can you also drop the top when you are in drive at 0mph? Maybe it never could drop the top in drive at 0mph and my mind is playing tricks on me!

View 7 RepliesThe top of my 2004 SC430 got stuck halfway open and I put it up manually. Now it does not work at all. The dealer told me it would cost $8,000 to fix! I love this car. How I can get the top fixed without going bankrupt?
View 3 RepliesI thought I'd post an update about my front end shakes that I've been working on eliminating since I bought my SC. They used to occur anywhere between 55-70 mph. The remaining shake occurs around 65-70 mph. I should mention that when I added H&R 25mm wheel spacers in the back and 20mm spacers in the front. I had the shakes both before and after adding the spacers though. The following list is what I've done over the past couple of years to try to eliminate my shakes:
1) New tires - Bridgestone Potenza's, nice tires, better ride.
2) Replacement, chrome, OEM wheels. Look nice.
3) Road force balancing.
4) Steering rack was replaced with a rebuilt unit because the old one was leaking. Came with inner tie rods and I put on new outer tie rods at the same time. No change in shaking.
5) Daizen polyurethane lower control arm #2 bushings.
6) Daizen upper control arm and lower control arm bushings.
7) Daizen steering rack polyurethane bushings. Still not perfect, but this made a huge difference.
I did the steering rack bushings today. I've really, really developed a dislike for Lexus steering bushings!
Some background: I had issues with my '01 LS430 steering bushings @ 85K miles. My only choice was to replace them with OEM. I should have replaced them at 50K. They were really, really awful. The interesting thing, though, is that they physically looked pretty good. The result is amazing; nice and tight.
The bushing design of the SC is essentially the same as the LS. But luckily we have more choices with our steering rack bushings than the LS crowd. I began to hang around the GS guys because their front end is quite similar. The '98-'05 GS430 uses the same steering rack and bushings as our SC. Sewell sells both OEM and an aftermarket polyurethane solution for around $30 complete.
At this point my SC tracks very, very well. The polyurethane suspension bushings probably add a bit of harshness to my ride but I don't find it objectionable and it's a reasonable tradeoff for the added precision in the front end. I don't believe that the polyurethane steering rack bushings have any tradeoffs at all. The remaining shake that I'm experiencing is pretty darn subtle but I'm not done. I'm going to rotate the tires tomorrow and see if anything changes. I'm also looking at toe in. My front tire wear tells me that I don't have enough. I've been running factory settings but I'm going to experiment with a bit more toe due to the additional road forces created by the wheel spacers. I don't give up easily!
