There are different types of DTC's (diagnostic trouble codes) that modules can set and depending on the severity of the code it can turn on your check engine light. If the problem solves itself within a certain number of ignition cycles it will clear itself. If the code is coming and going it is probably severe enough to have it checked by a professional...Hope this helps!!

Control off traction the trac off button lights up that wont let me turn it on what might be the problem


The light comes on and goes off when you start the engine as a test. If the light comes back on, there is a problem and you need to get the body computer scanned for trouble codes. The traction control uses the engine and ABS braking system to work.

My check engine light doesn't come on but my check trac light comes on but goes off


No, your check trac light is used to monitor the traction control system. It is sensing an issue in the traction control system, which is pretty complex. There may be a code saved in the computer that a dealer could pull for you.

Hello, VSC, Trac OFF and Check Engine lights turn on when i was driving. Whats means ? In Autozone said me that problem is with the catalyst system. Thanks for your advise.


when ever the check engine light is turned on for any reason the vsc and trac light also comes on to let you know they are not working, whenever the engine light is on the other systems can not operate if the engine is not working correctly, so its programed to shut down the trac and vsc when the engine light is on. the catalyst system means the catalic converter is no longer cleaning the exhasut to specs, this is caused by a weak bad converter or bad o2 sensors giving false readings you will need to have the sensors checked to see if they are the problem or the converter is the problem good luck.

The trac off light goes on and the engine light is blinking


This is common, when ever the computer sees a fault it will turn the light on and shut down the trac, the trac cant operate correctly when engine is not running good, you will need to have the computer scanned for codes, whenever the engine light comes on the computer stores a code with the problem, a flashing light means it needs attention asap, this mean its misfiring like a bad plug or sparkplug wire, the flashing is because you can cause damage to converter in the exhaust system, many autopart stores will scan the codes for free, for example they may pull a code that says po301 cylinder 1 misfire, this would mean cylinder 1 is misfiring, this take about 5 min, to get the codes, they use a small hand held scanner that plug in inside the car under the dash to the diagnostic connector which comunicates with the computer, hope this is helpful.

Trac off and check engine light for lexus es 300 check engine & trac control off lights & engine stutters while revving in park. Engine seems fine in drive... Reset lights without them returning...


A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.
