We are in possession of a 2010 Camry and just today we noticed that our park lights are on and for some reason cannot be turned off. I have looked in the manual and find nothing of any help. I did try disconnecting the battrry, but to no avail. Before I go to the de aler for repair I thought I would try the Camry Forum and see if anyone else might have had the same problem. We have owned more than a dozen Toyota vehicles

 

You disconnected the battery and the lights were still on?

Are these fog lights?

Both front and rear parking lights?

 

- yes

 

No to the first 2 questions and yes to the third quesion Thanks for your interests!

 

Find the tail light relay located in the relay/fuse panel behind the far drivers side coin box. The owners manual should have the location.

Determine if the relay is stuck in the On position.

Note, one terminal of the relay solenoid coil is always powered by the Alt fuse. The other terminal grounded by the Main Body ECU to turn the solenoid on.

What also can turn the solenoid on is a short in the wire from the relay to the ECU.
