Toyota Transmission Control Unit 89530-12210

**hrmotorsport** · 17th November, 2017, 12:57 PM

Hi all, i have a toyota transmission control unit with ref 89530-12210 with software damaged.

It comes from another workshop, they try to code with Launch but they bricked unit, then, they bought another one (used) and try to code, and bricked too.

I have readed 93c66 eprom from both units and are same code inside. I dont know if its normal, and individual code is stored in MCU or are wrong

Can somebody upload a working eprom dump of this unit? or tell me how to repair?

Thanks a lot!

Could you clarify from which ECU the firmware you posted? In the title of the topic, you indicated ECU 89530-12210, but in the uploaded files we see a different ECU number - 89530-12213.

Thanks

to make a long story short, thy did try "relearn" the MMT with launch thats why your file is empty as you say but actually its in relearning mode
the fact is that launch or what ever tool you use not does the relearn is that something (maybe) wrong with the transmission

so if you are verry sure that you did all the work correct on MMT and it still does not relearn you put in a file from a "relearned" MMT TCM as last sollution to get the N back on dash
