Courtesy lights - Toyota Yaris Forums

I have a '08 Yaris S and the map lights used to gradually dim after exiting the car or brighten when opening the door. That feature no longer works. However, the map lights work manually, and so does the dome light. Could the cause be the module for the interior lighting? It's not the door switch or a fuse otherwise the other functions would be affected.

It could be. That function is controlled by the body ECU when the switch is in door mode. You do see the door ajar light come on in the cluster, correct?

Yes it does light up with door open. That's the first thing I looked at and tested a few times.
