Dear Members,
I hope you can help me with my issue. I’m a proud owner of Lexus RX 450h 2012 and have issue with the Remote Engine Start module PT398-48112.Recently I bought this Module from Lexus dealer and got it installed it in Lexus RX 450h 2012.
Does anybody have the instructions for Lexus RX 450h 2012?

I went to the dealer to get the item registered in board computer and activate it.

Unfortunately, the dealer Germany Lexus Leipzig couldn't do it because the instructions were incorrect for Lexus RX 450h 2012.

Dealer told me some technical information below that you may find useful.

After trying to register the module with TechStream without using 1p diagnostic connection that is not present in my car, there was an error that the module cannot be connected and upon inspecting data stream, the error B2779 is present.
