Hello, we do not have this vehicle listed here in the US. A request was sent in to All Data but they did not have any information on a 2006 Toyota Crown 2.0 liter V6. We can try to send in the VIN number if you have it and resubmit the request that way.

The VIN number usually will be a 17-digit number. Is there a tag on the inside of the driver's door frame? And what country is this vehicle from? I will try one other location in the meantime. If you're able, the google play store has an app called "Carmin". It has your vehicle listed, but it's not in English. So, I can't identify the different sections in the wiring diagrams, but you may be able to. We do not have any affiliation with the app or the play store, but it's the only location that listed your vehicle. So, if possible, give that a try, and I will continue looking as well.
How many harness plugs does your ECM have?

Attached also find the ECU front view to know how harness plugs it has. I've tried Carmin but it's not available.

The closest ECM I've found was by part number but it was not the exact number. The 2005 Lexus GS300 3.0L uses the ECM part number 89661-3F340 and you are looking for the 89661-3F330. So, there is a difference in the ECM here. It has the same 6 connector setup, but the only way to know if it is even remotely close to your ECM would be to try to match up the wire colors, wire location on each ECM connector, and where each wire goes. I searched for hours, and this was all I could find. This Lexus has a different engine number as well.
But I'm going to ask some other technicians if anyone can come up with this ECM pin out or diagram,
is your vehicle really a 2.0 liter V6? That liter size seems small for a V6 although I did see a 2.5 liter V6 which surprised me.
Also, can I ask what kind of issue you are working on? Are you getting a code for a specific sensor or circuit?
