    Im from Sri Lanka. Toyota aqua radiator cooling fan working continuously once I pressed the power button with maximum speed. this was replaced with a brand new radiator after a car crash. no fault in fan control module. no matter if the a/c is on or off fan is working maximum speed. no check engine sign. could it be inverter related fault?

    Wiring diagram. The circuit isn't complicated, and it's overwhelmingly likely a simple mistake was made while replacing the radiator, but finding the issue by referring to the wiring diagram would be the fast way, and trying to do so without it would, probably, not be.

    it would be the next step. not sure if the fan control module is working properly

    no any fault code for tempreture sensor. still could not diagnose

    Do you suppose there is a fan control module? You'd probably see it on the wiring diagram.

    There's a wiki page here where Elektroingenieur kindly collected a lot of information about access to the technical documentation including wiring diagrams.
