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 RepliesI am hearing a single BEEP, about every 4 minutes, when I am driving. What the heck is it? I can't figure it out, looked in the Manual.
I found the Internal Alarm on Page 432, don't think it is that. The key is in my pocket, the car is on, I am driving! I've also removed the key from my pocket and set it on the front passenger seat, darn BEEP continues.
Yesterday, my SC430 started screeching and the VSC lights came on. I had never heard this alarm before -- sort of between a whistle and a screech. I was a few blocks from home, so I continued on. I did not notice if the ABS light was on at this time, but I don't think it was, because I would have noticed an unusual light on the dash.
I disconnected the battery briefly, but not 3 minutes, and the alarm continued when I switched the car on. This morning, I disconnected the battery again, this time for more than 3 minutes. Again, the alarm screeched when I started the car and pulled out of the garage. I switched it off, and then back on, and the alarm stopped. I thought I had solved the problem. I was wrong.
Later this morning, I drove to the bank, and when I took it out of drive after visiting the ATM, the alarm started again. It continued until I got home. This time, the ABS light is on, in addition to the VSC lights.
On the way to the bank, I made one fairly hard stop at a yellow light, but I have made far harder stops without any lights -- and especially annoying alarms -- coming on.
None of the posts I have found here mention this alarm when the ABS light is discussed.
I have checked the brake fluid level, and it was full. The car was in a Toyota dealership last month for its 120,000-mile timing belt, and the rear brake shoes and rotors were replaced then.
I have yet to begin checking the fuses, but I don't really think this is the problem. Before I try bridging the post in the computer terminal, I plan to visit the local auto-parts store that will read the computer for trouble codes.
I have a beep-beep-beep noise which is coming (I think) from behind the right side of the dashboard, and it occurs every minute.
I had this noise a couple of years ago, and it went away. Now it comes on every time I start up, and there are no indicator lights or gauge problems. I don't have to have the car in motion either.
I had the dealer disable the run-flat computer about 5 years ago, so I don't see how it could be that.
I just recently purchased a 2011 RX 350 AWD SFP w/ ebony interior for the wife. She loves the car and it drives like a dream.
However lately there's been a weird single beep that occurs every 15 minutes or so. I've tried replacing the key fob battery, making sure no interior/exterior lights are on, and making sure all doors/sunroof are closed. I tried locking the door to see if it works as well but no dice. It doesn't affect anything in anyway as everything is operating as it should.
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 RepliesI have done hours of searching about the rough idle on the SC430. What I haven't been able to find is any information about an intermittent rough idle. I have cleaned my MAF sensor twice.
I am having my mechanic replace the radiator tomorrow because of a leak and he is also replacing the idler pulley and the belt tensioner (one of them is making a noise and I purchased an extended warranty!) At the same time he will be doing a throttle body cleaning. I had my timing belt replaced as well as the water pump and had my mechanic check all the spark plugs and all were fine.
I am going to have him check the motor mounts as well. The RPM's are fine with the AC on or off and I have used Lucas fuel treatment on this current tank of gas without any results and my next tank I will try Seafoam as suggested by my mechanic.
I've been having an intermittent stall-out problem with my 2003 F250 5.4L (160k miles). The truck has been retired from DD to farm duty, hauling, and towing only. Over the past 9 months, the truck has stalled-out on me 3x while driving. I will be driving along sometimes at highway speed, sometime slower, and everything will die: no PS, lights go on all over the dashboard. It will not restart right away. I have to wait at least 20-30min to restart it and then everything is fine for several weeks and hundreds of miles.
There are no codes and I have been unable for reproduce it/cause it to happen purposely. My mechanic has changed the Crankshaft Position Sensor, and checked the fuel rail pressures. I also checked all the harnesses and fuses, cleaned the battery terminals, looked for vacuum leaks, and gave it a good look-over. The following are new: battery, IAC valve, fuel filter. After searching the forum I also pulled the fuse box and examined the integral fuel pump relay: it and the board looked perfect, no bulges, cracks, discoloration, etc.
My mechanic thinks this is more likely an ignition problem than a fuel delivery problem.
One channel (FM 90.3) delivers perfect sound for two seconds, then complete silence for a half sec. then two more seconds of perfect reception. No fade, no static, just on and off regular as a clock. This station broadcasts on two other frequencies which are behaving and 90.3 comes in fine on my other vehicle.
View 2 Replies2002 ... I've been getting a soft engine fault all three lights on and reduced power. This usually occurs if I accelerate hard but also happens if I take a small pot hole in the front, a little bump seems to trigger it as well. Also engine resets to normal after removing key.
It's not logging the fault as had dealer read ECU and said was not logged.
When I take off from a start it will intermittently stumble or hesitate, seems to be around 1500 rpm. have also noted it at higher speed while cruising. its more like a momentary power cut than a miss fire.
So far I have done the following
new fuel filters
clean MAF
new PCV valve
new spark plugs
check all hoses and plugs etc
injector clean
checked techstream for codes. there is one for a heated O2 sensor but dont think thats it.
2002. SC430
Lexus has diagnosed a ground fault with an intermittent connection.... I am not sure how to proceed ... Could it be a light bulb connection... or does it even have these? Can the part be serviced in place... or must I replace the whole assembly?
View 4 RepliesI'll sometimes transport item that are long and I need them to stick out of the glass hatch. Unfortunately then the warning light comes on and continually buzzes. Is there any way to turn this off?
View 3 RepliesSo my sc430 keeps giving me trouble and all the lights come on while i am driving and then it shuts off on me. I could be wrong but i think it has something to do with a iphone connection that i have. I originally thought it was the battery so i replaced that and it was running fine for a day with no issues. Then today shortly after i tried to use the iphone connector the same thing happened.
View 1 RepliesIts not super cold but in Tampa ever since I installed my headers and its 60 or below i've gotten the VSC and ABS lights on in the dash after driving a little bit. Typically this is a cold morning type thing.
I reset the lights and it went away for a few days (it also got 30 degrees warmer) once it got down to 55 the lights came back on. Parked the car went in to work and when I drove home the lights were off (without re-setting the lights).
I know the codes can mean different things. The car is driving the same as always too- I have PPE headers, Ingen Intake, and a muffler delete.
I have a 2007 and I've just developed my first problem since I purchased the car new in 2007. While driving, my headlight(s) will turn off by themselves.
Sometimes it's the right one, sometimes it's the left one, and sometimes they will both stop working. Turning the headlight switch off and then on brings them back to life.
What part in the headlight system is causing this?
I had a issue today and it made me scared to drive the SC ever again. While I was driving this light came on that kept blinking and making a beeping noises, after a while of blinking (approximately 30 seconds) the steering wheel jerked to the left and right really fast, luckily there was no car around me. I immediately pulled over to the shoulder. After a couple minutes I drove home on the service road without incident. Why this happened.
View 6 RepliesI have a 2007 and lately the driver's side headlight goes out sometimes when I'm driving. If I turn the lights off, and then back on, it will light up again and stay lit. Sometimes it will work for weeks and then all of a sudden it will go out. So I'm thinking of replacing the bulb(s)
Are the headlight bulbs in the 2007 SC regular light bulbs that I can purchase at a local automotive store?
I own a 2003 SC 430 w / 133K miles. It has been serviced regularly since purchased. While driving in rain , only the engine may suddenly growl and shake. No check engine light or other warning lights illuminate. When I pull over and restart the engine , it runs fine again. There are never any such problems when driving in dry weather conditions. What the issue might be?
View 4 RepliesI have an 02 SC430 and I recently noticed that my temperature gauge rose to 3/4 high after driving pretty hard on the interstate and then coming to a complete stop on side street traffic (mind you, it was like 95F outside) After traffic cleared and i started to move, the temp gauge went down to 1/2 and never rose again.
I tried to replicate the problem by having the car on idle and revving for a few minutes, but she stayed at half. I told my brother to watch the temp gauge if he drives it. He said the coolant was low and added coolant. Driving today, storming like hell, on the exit, i pull up to the red light and notice my temp gauge is to the cold position, but i have a check engine light on, VSC light on and VSC off light. I also noticed I'm smoking like hell, so i pull over to the nearest covering and pop the hood. My rad cap has popped off and coolant has spewed all over the engine. let it cool down and put the car on accessory.
At this point, my temp gauge is still at the cold position. started it up with no problems and the temp gauge shoots to the overheating position. I shut it down, let it cool. After a few minutes, i fire it up and drive it to the nearest gas station maybe 1000 ft away. Filled up almost 2 gallons of water and let it run with the rad cap off to get the air bubbles out. I notice a lot of air purging itself out of the coolant system. after running for 5 minutes with no variation in my temp gauge, i drive it for 5 minutes with no problems, no funny sounds, no funny misfire, no smoke (front or rear). The lights still have not come off... I can only attribute the overheating to air being in the cooling system.
I bought a 2002 SC430 about 6 months ago. The car has been flawless, until today. Twenty minutes into the drive while on the freeway at 75 mph the speedometer went to 0 and the ABS and Brake warning lights came on. The car and brakes seemed fine, I returned home. In the driveway I turned the car off and then restarted, all was good. No warning lights, and the speedometer worked on a drive down the street.
