Lexus ES 2007-12 :: Trac And VCS System Malfunction Warning
Nov 15, 2014
I checked the air in the tires on my 2008 350 ES with an outside temperature of around 40 degrees. Pressure gage read 25 lbs. I decided to add pressure to bring up to 30 lbs. Subsequently while driving, the Trac & VCS System malfunction warning symbol came on (the picture of a car with wavy lines behind the tires). Of course, the warning symbol of a red triangle with an exclamation symbol in the middle as well as a check engine light also came on.
I figured that the problem was that the combination of cold weather (for Houston) and the added air pressure resulted in the system interpretation of an increased skid or lack of control situation. So I let some air out to where the pressure in each tire is 27 lbs. Then I drove it 5 miles or so at speeds up to 50 mph. Made no difference. Warning symbols still there.

C1241 is low voltage warning and C1223 is an ABS control system malfunction.
Are or could these be related? Where should I start to troubleshoot the issue?

I have the VSC light, ABS Light, BRAKE light all on.
Check VSC System, Check ABS System, Check Brake System, Brake Malfunction.
I went to start the car this morning, battery was dead. Jump Started, and all these messages came up.
I have disconnected the battery for a good 2 hours, still no luck. I charged the battery. So its starts right up now.
The Brake Pedal is really HARD. When you brake, the car leans to the front Right Side.
When I reconnected the battery, The Brake Pedal is soft, but is instantly hard when Started.

I have a 2007 ES350, Navigation, climate control, touch screen all works, radio powers on and functions as if it was working. back about 6 months ago the sound audio began having a mind of its own and working randomly, very annoying to say the least. Well, now it quit all together, no sound for a couple months now.
I am knowledgeable in the area of car audio, electronics, engines etc... I think this car has a factory OEM amplifier, although I have not located it in the car yet. I know the amp is getting power because I can hear a turn on thump when I power the head unit on and off.
So I think there is a cable/connector between the head unit and the amp that was loose causing the erratic behavior, and now the bad connection = no connection as if someone yanked the RCA jacks on an aftermarket system.
FYI, I already pulled the head unit from the dash and looked for any loose connections, found none, put the thing back together and am getting really frustrated with no sound.

After driving most of a day on the road a red triangle warning light came up on the dash and a PCS System Check light lit together with a Check PCS System message in the display site. I checked the fuses and they seem to be Ok. The car runs fine and I don't feel any effect on driving the car due to this message.

My 2015 Lexus RX 350 has been indicating "Check AWD system, TRAC off" for sometime now. It all started when I overfilled the tank and it spilled over. The indicator came on after about 12 hours. What may be responsible. The car is barely 6 months old and don't know what to do right now.

Or to go for a second hand one..! I did some search and find out that this part it is not that easy to be damage..

My parking assist warning system has suddenly stopped working. (2007 LS460) I'm thinking I may have disabled it while pushing some other buttons or doing something else. I changed the distance to farthest but that didn't work. It was working perfectly last week. I did disable the auto down tilt on the steering wheel. Could this have also disable the parking assist?

Just noticed that the passenger side daytime running light is out. There is no warning message shown on the dash? Is this normal?

I have a 2007 RX350 and these lights come on intermittently --> TRAC & VSC LIGHTS ON. ALSO ABS, BRAKE LIGHT. When I turn the car off and on again they would disappear. So I cannot take it to Autozone (For code read) because the problem goes away when car is shut off/on.
I believe it is tied to the front brakes which are new but the steering wheel shakes when braking. I had the rotors turned a year ago and it seemed to have fixed the problem but now the shakes are back and so is the light problem.
This makes me think that there is a loose connection (Wire / connector) around the front brakes.

My wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?

Alternator on my 2006 GX failed, caused battery to discharge and vehicle stopped. Alternator was replaced, battery (was new) is testing fine. All electronics and indicator lights normal except Nav system. Display reads insert proper disc. I have ejected and reloaded disc multiple times, no change. Disc is OEM, one release back.

I have a 130K+ 2002 SC430 in which I recently started to smell gas in the cabin when air vents were set to pull air from outside. Within two weeks, I got the check engine light with two codes, P0440 and P0446, which mean "Evap Emission Control System Malfunction".
In doing some research the check light light could be everything from a gas cap which is not tighened properly, to a bad "charcoal canister " (whatever exactly that is), to a cracked or disconnected "Evap Hose". The only other SC430 related thread I could find on this topic is [URL] ....
If it factors in, I only use 93 octane gas. Interestingly enough, the check engine light came on within 30 seconds of me using the window washer to clean the windshield (at highway speeds), likely a coincidence.

I have Lexus 460 LS L 2007. Few months back changed the battery and every thing was ok. 2 months after I had problem in the sound system ( radio and dvd ) which was on and off. One month back suddenly I had all the warning lights in the dashboard on with massage saying that that the brake system is malfunctioning and check the ABS system.
I took the car to LEXUS dealer and they reprogrammed the computer abd then every thing went back to normal and the problem fixed. Two days after I had these warning lights again with the same massege. I do not know what to do ??

I own a 2002 SC430 with 20,200 miles on it which I purchased new. The other day the check engine light came on. I checked it with the code reader and got the following 2 codes. P0300 (random multiple misfired detected) and C1201 (engine control system malfunction). The car ran great before, now running real ruff and when you drive it has less power.

I have a 2005 Century that show ABS and No Trac warning lights. I use an electrical cleaner spray (without lube) on the front passenger side ABS connector spraying male & female ends. The warning lights don't reappear and brakes seem to function normally.
Then a few months later the same warning lights appear, I repeat the spray and everything seems to return to normal again. This process has been going on for about a year.

I have never had this experience in 33 years of car ownership and driving in snow. Have a 2012 v and absolutely no traction in snow. Got stuck in my flat driveway, on 1" of snow in parking lot, up a hill that required pushing all the way up the hill by two people. Is there any way to disengage the TRAC system? There is no moment in which the car bites into the snow and moves. It basically just rocks (too strong a word, because there is no movement) in place with the TRAC light on. I basically can't drive it.
