Lexus SC430 :: 2005 - Alarm Sounding Intermittently?
Sep 18, 2013
I have a 2005 SC430 and all of a sudden the alarm is going off. Twice today once at 6am and then at 7.30am. Since then (it's nearly 2.30pm) - nothing.
I've not changed anything inside the car since it went off this morning - and nobody was trying to get into the car. The problem of course is that it autolocks and turns on the alarm.
This has only just recently started happening. Is there anyway just to lock the car and disable the alarm?

My Lexus SC430 parking sensor alarm sounds intermittently while I am driving. (No, I do not tailgate the car in front.)
It has happened several times, all but once when it was raining. On that one occasion, the sun was shining. It happened again today while it was raining, and continued to sound after the rain had stopped, but the road was still wet.
What could be causing this to happen, and how can it be prevented. I have decided to fit an ON-OFF switch, if the problem cannot be solved conventionally.

We just bought a very clean 06 XL with low mileage. After getting home and getting out of the car, I went back and opened a door to retrieve some papers. The damn alarm went off, and of course the keys were in the house. The doors had not been locked. It does this every time. We don't lock the car in the carport, and if anyone opens an (unlocked door) the alarm sounds. I tried putting it into valet mode, but no difference. Called Toyota customer care, and they said according to the vin, it did not come with a factory alarm, so must be a dealer thing. How to disable this thing or change the settings? It sure looks like a factory alarm.

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.

My 2005 Ford Escape's alarm goes off intermittently throughout the day and night. This usually occurs after the door ajar light comes on while I'm driving. All doors are secure and I've even replaced the latch assemblies on the driver's door and rear hatch (these are the most used doors). There must be something in this circuit that is causing this to happen. It is frustrating having the alarm go off in the middle of the night when there are no obvious intruders. How can I resolve this issue without replacing any more latches or spending a large amount on diagnostic tools from Ford?

I left the lights on last night in our Santa Fe, and drained the battery.
Took the battery out and up to O'Reilly and they recharged it for me on their charger. When re-installing the battery the car alarm goes off as soon as I attach both battery cables. Turning the key in the ignition doesn't kill the alarm.
How do I reset the alarm and shut it up?

The navigation door stopped working about 6 months ago while the navigation screen still worked fine. Two weeks ago the door started to work as it should be, but today it stopped working again.
According to other threads people have published this could be from the door being off-track, a broken motor, and a blown fuse. Obviously none of these scenarios could be apply in our case.
Btw, I checked all fuses and could not find any problems with them.

On my 2007 SC 430 I have a passenger headlight that appears to have a mind of its own. It works intermittently. I know that it is programmed to go off when the car is in park, but that is not what I'm talking about. When I start the car after dark both sides will be on but at some point the passenger side will go out, not all the time, but quite often. I have checked for loos wires but have not found any.

I just got a beautiful red '06 with only 19k miles. It's my second SC, and I can't believe how much I missed it after a four year break.
However, there's already trouble. The roof only opens intermittently. When it works, it's all good, no vibrations, nothing off track, smooth operation all the way open and close.
When it doesn't work, the red light on the open/close button will NOT light up. Nothing happens at all. I will come back to the car a few hours (or minutes) later, and it works fine. The problem never occurs for closing, only opening. Also, several times now I have closed my roof, and then immediately tried to open it again, but no deal. Those symptoms make me think it's not the ECU, but one of the sensors.
BTW, there is no Luxlink installed yet. I have yet to find one that includes the double-click option

I own the above described vehicle; I'm at about 196k and I'm the original owner. It's a quad cab, 2002 7.3L with power everything. I believe it's the XLT package (it's not in front of me... I'm at work. CONFIRMED... XLT package).
Currently, it's the workhorse and back-up for the family, not my primary driver - luckily. I've had failure if the automatic door lock on the rear pass. door, and a sticky lock on the rear driver's side lock - they've both been in this state for at least the last four years, no problems beyond the hassle of manual manipulation of the door lock from the inside - otherwise no electrical issues really to speak of.
Three weeks ago, we went to the snow. I rarely use the 4x4, but found that I had to use it that day to get out of some mud - it worked fine, no issues. In addition, I also used the cruise control... something I do rarely, but have not had any issue with it either.
In exiting the area some hours later at the end of our day, I noted two things... the "door ajar" dash light was illuminated and did not shut off through the drive home, and the dome light remained on until the battery saver shutdown shut it down... quite some time (where normally a key in the column turned past the insertion would shut it off).
When I drove home I used the cruise control, as mentioned, and it worked fine.
In exiting the vehicle while at home, as soon as the door was opened the horn started blaring panic alarm style - honk, honk, honk, honk... - and when the batteries are attached, there is nothing that stops the honking, except the battery saver timeout. BTW... no key in the ignition.
I don't use the FOBs... the batteries were dead anyhow (and I moved the FOBs out of range of the vehicle).
Attempted fixes:
- Lubing the lock/WD-40, then shutting/opening the doors (no luck/no change).
- Pulling door panels, removing locking mechanism, removing door ajar switches (I don't know what they're called), manually manipulating the piston AND checking each with a multimeter. (NOTE: One "seemed" not to work properly, so I purchased one from dealer and placed it back... still, no luck resolving the issues overall).
-Checked the wiring looms supplying all four doors - no broken wires noted.
- Replaced the two vehicle batteries.
I'm at a loss and I'm hitting up this forum before I move forward...
I've read that there are issues with the VSM for this year's model, but I'm hesitant to purchase the module without further feedback from a tech. I've read some general posts about alarm systems (doesn't apply to me) and horn issues (but those were horn constantly blaring... not the intermittent horn blasts of a "panic alarm sounding."
I've heard that the GEM and clockspring could be an issue, but I have to look more closely at the associated problems (like recheck to see if the cruise works... door windows go up/down like some threads have mentioned...). I have also read that the door ajar sensor switches attached to the automatic locks could be culprit, as they may "work" when pulled out, but not work when they're installed in the vehicle.
Ultimately, what the cause to the panic horn beeping, dome light and door ajar instrument indicator being on.

I hope I didn't just happen to notice this today if it has been going on for any length of time now. I started up our '05 this morning and she's definitely whirring at idle. I do not recall hearing this sound at all recently and we've been on a couple lengthy trips with it. Fluid levels all appear normal.
Had my wife start it up too and she agreed that the whirring was not there previously. What are the most likely candidates into which I should look first? It' not high pitched, but a steady muted whir of the type I might expect to hear when two gears spin while making contact.

I have an '05 Lexus SC430 with 53,000 miles on it. For the past couple of years, I have noticed an intermittent antifreeze smell (sweet odor) when driving. It never lasts for long and is apparently coming out of the vents. I can not figure out any common denominator to cause this, other than the radiator was replaced in Nov. 2014. My long-time mechanic has ridden with me a few times and I am unable to recreate for him to diagnose.

I bought my 2004 SC 430 used in 2005. The seat belt "reminder" buzzer or ding was silent and I have left it that way. Now that I am a member of this forum (just joined mid February) and after having so many questions answered solving problems I have been living with (like a steering wheel squeal when it retracts to let me out of the car, and a knocking above and behind the back seat, which turned out to be the shell that goes over the top when it is down, and lots of other solutions to things I did not want to go to the dealer about) I decided it is time to see if I can reconnect the seat belt warning. So, might that be a fuse?,Or maybe some wire under the dash that has been unplugged?

drive an '05 sc430 and the steering wheel shakes at above 50mph when I lightly step on the brakes. I have recently had my brakes done and an alignment done as well as both rear shocks replaced.

Just 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.

Weird seat heater issue on my 05 TAP/Ecru. Drivers side seat heater tends to fail intermittently after I apply leather care liquid on the seat. Does not happen on the passenger side. In winter, it failed for nearly a week before coming back to life. Yesterday it failed for the evening, then started working again today. Each time right after I applied leather care to the seats. Same amount applied to passenger and driver's seat and the passenger seat is always OK.
What is causing this ? Of course each time I go to the dealer, it is working fine !!!!

I have a 2004 Prius with 191K miles. When purchased in November of 2008 the 12V battery was replaced (mileage at the time was 70K). Over the last 2 weeks my alarm has been going off daytime, nightime with no regularity.
I have replaced the battery in the FOB (I only have one) and did this yesterday. Last night the alarm went off 4 times between 11pm and 1am until I disconnected the 12V battery.

I have a 2003 Camry. Recently, the dash board signal has started to turn on i.e. Battery,abs,brake, etc. when I accelerate. Around 1000 rams the light come on,then will turn off below the 1000 rpms. Now, at 2000 rpms the heater fan will increase speed to maximum.
I had the battery tested and it checked out ok. Could this be the alternator?

Experiencing a plastic sounding rattle (exterior) when hitting road bumps? This noise appears to emanate from around the wheels and can only be heard when the windows are rolled down. Model is 2014 250 fsport. The car sounds cheap when this happens.

I have a 2004 Hyundai Accent. The factory alarm goes off intermittently and the central locking engages at times without warning.
I took it to an Auto Electrician who checked it over but couldn't work out the problem. So i took it to the dealer who said it was most likely the bonnet sensor. I wasn't convinced but they went ahead and charged $150 to diagnose and adjust the sensor and said everything would be fine.
Within one day of being 'fixed' the problem has reappeared. I am getting sick of disconnecting a battery terminal every night....
