Oh, ok.
Thank you for your quick response though.
Well, what I am looking for according to the service manual, appears to be the T-PL relay.
I will keep on looking

OK - The T-LP relay is located within the body ECU, so theoretically the only way to replace it is to replace the entire body ECU assembly, which is that whole under-dash fuse panel piece.

Ouch! This sucks.

The good thing is that looked further into the technical manual, and T-LP doesn't fit 100% the symptoms of my problem.

Could you please have a look into my problem?
Hopefully it might be something simple for someone with your experience.

Also when I turn the lights stick to the first position, not even the dashboard's lights dim down as it always did.

I believe this narrows down my problem to either issue with the stick itself, relay/fuse, or the wiring between the 2.

Thank you

Thank you

You can do an easy test to see if it is the relay or the headlight switch. The picture below is of a US Yaris headlight switch connector, but your looks the same, with possibly some wires in different positions.

To test the relay with bypassing the switch, using a paper clip or piece of wire, jump the position 10 and position 13 wires. In the picture below that would be the bottom left wire and the wire 3 positions to the right of it.
