Hello, I just purchased an 09 Prius. The previous owner told me that all the door lock/unlock suddenly stopped working. I was hoping it would be an easy fix, but no luck. From research here, I've tested the battery and it's testing 12.5V. I've checked the switch under the steering wheel. I've replaced the fuse under the dash (no. 11 door locks).
Is there a relay somewhere?
None of the doors lock/unlock either with the door lock switches(driver and passenger door) or the remotes. I can't even open the back hatch, it's locked and I can't find a way to manually unlock it.:headbang: I can get into the front doors with the manual key and manually lock and unlock the back doors from within the car. The remotes turn on the alarm. Any help would be much appreciated.
I'm going to look online for a downloadable service manual. Any ideas on that?

Ok, got it fixed. Turned out to be the Body ECU. Replaced it with a used one and all is working fine.
