Malfunction Codes after Battery Replacement?

Alright folks, some good news. I paid 140 to have it fixed at the dealer and got a somewhat breakdown on how to fix it. First bit of good news you did nothing wrong aside from possibly having the ignition cycle on and off within 20 seconds of the battery, a low battery, or an ignition cycle without the room fuse installed. So this results in DTCs that cannot be cleared from memory.

So the to perform a reset,
Remove the room fuse
Changing the miles to kilometers and the Temperature Celsius to farenheit.
Then holding the trip button for 5 seconds
reinstalling the room fuse and then clearing the DTCS with what I am assuming is a OBD scanner.
(Disclaimer: This is what the tech wrote in the summary, I have no idea if this is the whole process. Honestly do this at your own risk.)

I hope this helps someone. I was freaking out thinking I broke a confuser(Computer).

According to the Owners manual, it protects the overhead light in the car. Insane to me that it is apart of a process to reset the car in some fashion. I wrote to Mazda corporate how ridiculous it is that I may have to go to a dealership next time I want to change my darn battery.

I'm glad I read this while I still have my OEM battery. I think I'll rig a battery saver.

Don*t keep pressing the TPMS button or it will lock you out and only the dealer can reset it. It will initialise after a period of running. You only get two presses before lockout.

The EPB can lose its memory after battery replacement. Put it into maintenance mode then reset it.

There is a number of procedures to follow after battery replacement but I haven*t got time to post them now.
Please post official Mazda procedure for battery replacement if you have time.

I replaced the battery without a memory saver, and I had no issues at all other than opened and closed the driver side power window for a reset. I do have revised rear disk calipers installed by the TSB.

So does this mean that NOT removing the Room Fuse would prevent your situation from happening?

Finally had a chance to give this a shot. Unfortunately no dice. When you pull the room fuse it kills the radio/display so you can't change the miles to kilometers and the temperature Celsius to Fahrenheit. I did try this in different ways like changing them first and then pulling the room fuse and clearing the codes, but to no avail. The home solution search continues...

Regardless, thanks to VobraZero

I'm sorry to hear that man, that is what my technician wrote. I best you could do is insist that you know what it is and have them simply reset it and charge you no diagnostic fee. I had a feeling it has some things exempted from it. Honestly it should be in the damn owners manual on how to change the battery. From what I gathered turning the car on too soon after putting the new battery in doesn't let the car reset properly.
@concept I really have no clue to be honest, I wouldn't wanna speculate on angry pixies and confusers. (Electrics and computers) I wish Mazda would just give us a definite answer.
 
No worries man...I may give it a few more tries in different orders. If I have any luck I'll be sure to report it. I doubt that the 3 (you, me, the OP) will be the last to have this issue. About the time when 2016 owners start replacing their batteries...

I had Sams replace the battery in my early 2016, no problems. I do not think they used a minder...
