Lexus LS 2007+ :: VSC / ABS And Brake System Malfunction
Mar 19, 2015
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 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.

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.

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 ??

1. I think my battery is getting weak.... when i cranked it, it didnt sound strong and the original battery eye says to add distilled water. I am thinking about getting a replacement battery at Costco.
2. so right after it started, the message of "Check Brake System" shows up. Tried to restart but no go. Drove about 15 miles and all seems fine but message is still there.
* is it OK to replace with a Costco brand battery (they have a great returns policy) and is there anything i need to do before or after replacement?
* could the Check Brake System be due to the weak battery? How can I reset it?
* Anything else that can cause this error message?

This morning, during a routine drive to work in my 2007 Toyota Prius, my instrument panel lit up with the brake light and ABS light. The car braked normally, although when I tested the anti-lock brakes in a parking lot, the car slid and the ABS did not engage. I brought it to a shop - they ran a diagnostic and came up with a Malfunction of the Hydraulic System - right rear. They said I need to take it to a dealer for repairs. This car has cost me a lot in repairs over the last year...and with 170,000 miles, I'm not willing to put in a lot more.

I have a 2006 prius I got used and in good condition about 3-4 years ago. I never had any problems until a cop pulled me over and it turned out my parents had decided not to notify me they hadn't renewed my registration and my insurance they've been paying had ran out. I've since learned my lesson on keeping up with the dates.
I "luckily" got to go home with just some tickets. It sat about 2-3 months until I could get the money to line everything out. I ran it at least once a week but apparently that wasn't enough? Now that everything's up to date I started driving it and the yellow circle with the (!) in it is on. The Master system light, the check malfunction light, and the hybrid system light is on.
It seems like it applies the brake when I'm driving constantly now. It stalls when I first try to speed up. And the fan? on the passenger side of the back seat is always running for some reason. I tested my battery volt and it's at 9.2.
I took it to an auto shop today in town. I live in WV in the backwoods. And they wouldn't hook it up to check for codes and referred me to a dealer about 30 min. away... I've never had any problems with this car before.

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?

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 was having ABS Brake Malfunction alarms. After turning the car off/on it would reset. It took the dealer time to figure it out because it would not leave any error code on the computer. They finally got it to have the issue while their computer was connected and could see the error code. They then discovered there is a technical bulletin for this issue. The ABS Actuator Assembly needs to be replaced.

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 own a GS450h and I've had a "Brake Malfunction" display message with various lights and messages. It tells me to Check ABS, VSC, and other items. The brake light and a couple next to it are also lit. I connected Techstream and these codes were found. I've had the wheel bearing changed, however that was a month before these codes popped up.

My wife loves this car except when it won't start, and unfortunately that's happened from time to time recently. The first time was when we were out of town, when we got home, it wouldn't start. No big deal. But since then, it's developed the habit of draining the battery over very short times. We put in an after-market stereo a couple years ago, I thought that must be the problem. Pulled the fuse so it wouldn't play. Overnight the battery ran down. The battery is almost new. I took it back to the seller of the battery and had it checked. It's fine. My nephew told me that when he had a 1998 ES300, it had a similar problem. Obviously some type of battery drain, but I'm at a loss. The Lexus dealer cannot diagnose the problem.

Issues:
1. Just put her in for the SECOND brake actuator replacement at 45k miles. First failed at 22k miles, so they DO have that consistency thing nailed.
2. Also had to replace BOTH B-pillar trim pieces which have soft facing material that cannot withstand the constant barrage of seat belt buckles banging into them during retraction. They start by showing marks, then dents, and finally the material gives up altogether and begins to shred.
3. Brake shudder due to "rotor warpage." I believe this problem is due to production engineering (or lack thereof) during final assembly. Hub runout at maximum combines with rotor runout at maximum, even though both are within tolerance, to produce a stackup tolerance outside the spec which results in warpage given enough thermal cycles. The reason the problem occurs only rarely is due to hub and rotor tolerance variations AND the various stackup combinations arbitrarily selected during final assembly of rotors to hubs.
4. The recirculation-biased AC causes mold (and odor) buildup in the AC system. Since this "choice" was made by Toyota to gain U.S. CAFE credits, the fault lies more with EPA and DOT than with TMC. Still, the unsuspecting Lexus customer is the one who suffers.
I'll buy an extended factory warranty on the car, run it for another year (20k), then sell it before the chickens come home to roost.
