Hi, can I replace the hv ecm with a used one?
2007 toyota camry hybrid.

you can but it will need to be reflashed by either the dealer or a local ecu flashing service.

Thank you. So no other sccaner will do it? Or locksmith? Also when plugging the battery back, wich battery do i connect fist.

disconnecting a battery is negative first. reconnecting is negative last always. and i doubt a locksmith would be able to do it. but a local airbag service may be able to do it and there are some local ecu flashing services around. but the best bet is always the dealer.
