Here are pictures of my drive unit inverter.

I apply 70 psi of air pressure and it holds well. This thing must be leaking when it got hot. It looks like the leak is from one of the three coolant ports in the center.
The following is the invoice from Autonation Toyota

My next question is can I just clean this inverter with contact cleaner and install it back? It is probably fried from the coolant!
If it is bad can someone tell me where can I get it? Thanks.

Call Quick Charge Power and ask for Tony. Explain what happened and ask his advice.

Just done talking with Tony and he has one available for my car. I am considering it, not sure yet.

I sold this RAV4 EV owner a used motor out of another car. Hopefully, he can get it installed in his car, and take it to the dealer to have the computer programmed to accept the new motor.

He should be up and running in no time. Hopefully, he will want to install JdeMO on his car, so that he can drive the car throughout the area without constraints. There are about 300 compatible fast charge stations in Southern California that can charge his car in 30-45 minutes.

I have the old motor, so perhaps I will make it a display unit.

Tony,
I got it installed these weekends and now I am waiting for a tow truck to bring it Carson Toyota dealer to have it flashed for the new motor, not Autonation Toyota Buena Park who has never responded to my email about how much they would charge to do the job.
I will keep you posted.

Was (self-)revised. ...
Note. SAFETY RECALL F0I "EV GATEWAY CONTROL ECM SOFTWARE UPDATE" (March 11, 2015) recommended to update the software to new calibration 1.3.101 and "This update will be performed at No Charge to the vehicle’s owner".

The dealer has had my car since Monday, May 14th and I have not got it back yet. The adviser said they had a hard time to get the car to accept the software after installing a new 12 volt battery, will keep everyone post it.

That’s not a “recommendation”. That firmware update is actually a result of a US Government recall. They are REQUIRED to update the firmware.

It is known which codes are stored?
For example, DTC P312F and Current Active Alert GTW_d001?

They all the more (especially the fact that), they must to update the software during the previous visit, for which a lot of money was paid. Or, at least, REQUIRED (necessarily) inform the client about the need for such a "modernization" of Teslas firmware to version ID 1.3.101 (UDS Drive Inverter: 0.25.13 = > 0.25.20, UDS BMS: 0.21.26 = > 0.21.29, Gateway: 0.61.31 = > 0.61.49, UDS Pedal Monitor: 0.5.10 = > 0.5.12).

Dear TonyWilliams, now is known the cause of the malfunction (the cause coolant leaked) of the "native" Traction Motor Assembly of RAV4EV of respected rav4evuser?
