    Hi people. Been battling with a 2015 Prius, that I need to get the dashboard light, and the ignition to turn on, but without success.

    When I turn on the ignition switch, the dash lights are blank, with only "key not detected" displaying, and the key sign blinking.

    I recently replaced the HV ECU, driver side fusebox, smart key module, etc, because the vehicle was a flooded one.

    I am trying to get access to the ECU ID CODE module, but without success.

    A colleague told me, the ECU ID CODE is behind the AC evaporator. If so, it appears , I need to remove the dashboard again.

    I want to confirm if that is correct. Does anyone has the body main wiring harness, that can point me to where the module is?

    Thanks for the help.
