Check Engine/Traction Light

[kerrih74]

I have a 2010 Lexus RX 350. Yesterday I was leaning over to get something out of the passenger side floorboard and I heard 3 beeps. I wasn't sure what made the beeping noise. The next time I was driving the car the car, the check engine light and traction light came on. Any ideas how to clear it? The traction is on.  Thanks!

You should be able to check the code number and then clear it with an OBD II scanner. But also check the water level in your battery, and it's date of manufacture. Knowing the code and looking up what it means is important.
