ECU TSB Update

They're all in the 1st Post. It is model year and transmission dependent.

 

Anybody knows if the Canadian 2021s run on AT ECU IDs 04C00 or 04C20?

 

Hey, Folks.

@dilbert created a handy spreadsheet to connect the TSBs to the Tacos and CUW files to flash. It looks a whole lot better than my mumbo jumbo.

Thanks!

 

alright, so I've been to AutoZone, Advanced auto, and o Reilly's. They all told me their readers will not read the Calibration Id or ECU ID. What's my next step to get this figured out? Already posted on a local forum and didn't hear from anyone whos able to update and help me out.

 

Did you test drive any of the autoparts store readers? Those guys probably don't even touch anything but DTCs.


The easiest way is to get an ELM327 OBD adapter and grab a phone app like Carista or OBD Fusion. Being universal, the adapter should be good for a long while. Mine was less than $15 and I got it over 6yrs ago.

If I was buying today:

Also, someone recently posted that the Autel adapter will show the ECU ID with the basic / free version of their app.

 

Or just buy a tactrix, then you’ve already got it when you see yours is old and need to apply a TSB

 

While that's a good idea, I'm not too sure if I'd be comfortable doing something like that myself.

 

If I were doing it all over again. That is the smarter play.

 

If I can do it . . .

 

If @Mooseditty17 can do it, I’m sure you can too!

 

Everyone is nervous their first time...



Pun intended. It's Friday after all.

 

Curious to see if I can get my local dealership to do this update as I don't have a laptop or anything to do it myself. Fingers crossed, maybe I can get it done over the holiday break.

 

I may have to go that route even if I don't want to because there's only one dealer in phoenix known to actually update it and I'm going to reno soon and I'm less hopeful for out there.

 

@G8R_Taco is up in Jacksonville?

 

Put it this way. The Tactrix hasn't lost value so far. Guaranteed that you could sell it locally.

 

I’m kind of surprised there isnt a community tactrix cable getting shipped around for TSBs yet like the ECGS bushing tool.

 

That was how I did my first TSB flash. Paid shipping and a refunded damage deposit on a borrowed Tactrix.

 

downloaded techstream because my dealer said that the tsb my tacoma 2019 doesnt qualify and my computer is different from the tsb statement...i think just dont wanto to do it...so after download tech the app give me a warning for a critical update...i cant get rid of the waning...any suggestion?

 

Use it offline, turn off Wifi.

 

Turn off WiFi. It will then give you a 30 Use countdown that will reset the next time that you accidentally try to connect with WiFi on.
