2002 lexus RX300 125,000 miles. Service lights are coming on and staying on. I reset everything once by disconnecting the battery and they came back on after a day or so. Where do I start and what should I look for?

thanks in advance!

Go to auto zone and get the codes read for free, come back with codes.

 

Check to see if the vacuum hose is disconnected.

I had this happen before. Those three lights came on. Took it to the dealership to have the code read and they said it was the vacuum hose.

 

ok thanks guys, gonna check the vac hose and then reset computer by disconnecting battery. If no change there then I will go to autozone and have codes pulled.

thanks again so much,

Sully
