Hello. Welcome to Just Answer. Please allow me to assist you. Normally, when we see a 'no communication" issue, we suspect a bad electronic control unit. This is, of course, assuming that the scanner is compatible with this vehicle. Not all scanners work on Toyotas.

Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

Then I would be looking for an interruption of power to the ECU. Most likely a blown fuse.

You need to see if you have battery voltage at the socket for the 5 amp EFI 2 fuse. Fuse panel under the hood.

If EFI 3 fuse is blowing, this fuse powers the Oxygen sensors. Unplug them and see if a new fuse does not blow. The oxygen sensors are the ones after the catalytic converter.
