Question about Lexus LS 430

1 Answer

Traction control light

My traction control and vehicle stability system goes off intermittently and the same is even a more chronic issue with my adaptive front headlight system. I do not want to take it to the dealer and have a big bill if the only issue is their hitting a reset button or something very simple.

SOURCE: ABS light and Traction control light stay on.

That "grindy" feeling is when the ABS kicks in. It's only suppose to activate when you slam on the brakes and the wheels would normally lock. Instead, ABS will very quickly pump the brakes on and off, to prevent the wheels from locking (making a giant skid mark) and stopping the car more effectively. Generally this only happens if you slam on the brakes or loose traction due to rain or snow while braking. If this is happening often and the brake light is on, on the dash, then you need to get this checked out by a qualified mechanic ASAP.

SOURCE: VW PASSAT 03 V6. EPC AND TRACTION LIGHT COME ON INTERMITTANTLY.

First, to read VW codes you will want to get yourself a $50 VAG tool. It will read all your systems, not just the ECU.
Electronic Power Control can go out for several reasons. Check your brake lights with the car running. Check you radiator fluid level. If the car is running bad, you could have bad spark plugs/ wires or ignition coil.
The traction control is tied into the ABS system and often causes problems here as well. Each wheel has a speed sensor and magnet wheel in the hub. You can check these for damage by removing the tires for access. The sensors come out by hand, and inside the hole they come out of is the place to check the magnets with a flash light. Apply a small amount of wheel bearing grease to the sensor.
The control unit goes out in these systems at an alarming rate. They can be easily removed, and repaired for under $200 at modulemaster.com
Since it is intermit, I suspect most likely a loose sensor, or electrical connector.
If your brakes feel squishy at all, bleed the brake lines of air and contaminants.
Good Luck!

SOURCE: service stability system control message came on.

Hi. Go to the nearest AAMCO repair shop where they now do a free computer scan. OR call around to a few auto parts stores until you find one that does a free car computer scan. The scan will tell you what issue the computer is identifying. Many times the only problem is that the sensor is bad. In your mom's instance, chances are that the sensor is bad and could be replaced. When the car's computer is scanned, ask that that the computer be reset. Regarding driving, not to worry. If it is only the sensor, then the stability system is still ok. If there is an issue with the stability system, it will show up and can be fixed. Regards, Joe

Get your system checked for malfunction codes. Sounds like there is water entering the sensor harnesses under the vehicle. Doesn't take much to set off the malfunction light.

I have a wrench with a car swerving light up every once in awhile but I have no idea what it means and I have no idea what stabilitrak is


{: ) A car swerving light on the instrument cluster is the StabiTrak indicator, sometimes called the traction control indicator. A wrench beside it tells it requires servicing.

Your vehicle is equipped with StabiliTrak, which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
Traction control activates when the controller senses wheel spin. StabiliTrak will selectively apply the brakes and reduce engine torque to help regain traction.
Stability control activates when the controller senses a discrepancy between your intended path and the direction the vehicle is travelling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help guide the vehicle in the direction which you are steering.
When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing.
When the StabiliTrak system is both on and actively controlling the stability of the vehicle, the StabiliTrak light will blink for the duration of the event.
You may also feel or hear the system working. This is normal.
StabiliTrak will turn off automatically if a problem is detected in the system. The StabiliTrak light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak service light) does not clear itself after restarting the vehicle, you should see your dealer for service.

What does the indicator light above the odemeter mean when it flashes- it the light that is shaped like a triangle with a almost complete circle around it.


If the light you are seeing is yellow/orange in color (see below example), and flashes intermittently when you're driving, that is the Dynamic Stability Control indicator.

DSC is always turned on, by default, unless you turn it off. The indicator light will flash whenever the DSC system detects any loss of traction or stability (oversteer/understeer), when your vehicle is in motion.

I have a 1994 camry, last night a warning lamp came on in the lower left of the instrument cluster showing a car with lines coming out the back of the car, I have no idea what it was trying to tell me and...


Really it is not an issue but you might want to confirm by running a scan.

The signal you have on your Toyota is:-

1. If the lines are straight it means some of your tail lights are bad;

2. If the lines are not straight then it is VSC (Vehicle Stability Control) which indicates that the vehicle is not well balanced.

Good luck and rate this solution.
