Yaris HB RS 4 door 2010

Hi, i need help.

The fuses are ok. The car battery is ok. The battery of the key fob is good. The lights flash once when the lock button is pressed, and flash twice when I press unlock. The door ajar indicator light turns on when a door is open and turns off when closed. But nothing lock or unlock, with the control unit button or with the key fob, no door lock or unlock. Look for what is the problem. :help:

Sounds like it might be the 25A D/L fuse on the Main Body ECU block. Look under the dash panel by the OBD-II port. If the fuse is blown, that means there's a problem with one or more of the door lock actuators.

Thank you CrankyOldMan.

That was the 25amp fuse.
I was probably in the rush when I first searched.
Not easy upside down.

Yes, those are tricky to get to. Glad I could help!
