Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.

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.

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

ok. I need to get my papers on this. I will get back to you shortly.

ok
Expert:  Toyota Service replied 1 year ago.

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.
