Help Regarding Mazda 3 Battery Management System reset

Hi all,

I've just recently purchased a 2014 Mazda3 2.2 diesel.

Long story short, the guy had it sat on his driveway and the battery died, so in order for me to test drive he bought and installed a new battery.

This has thrown up a couple of lights on the dash:
- the TPMS warning
- the DSC warning
- the Smart Brake Support warning

Now, I've read that this can commonly happen when replacing a dead battery on a Mazda3 and I purchased FORscan in order to reset the BMS.

I can not, for the life of me, find a BMS reset option in the software! I've tried both FORscan for windows through the extended license option, and also FORscan lite on my android phone.

Can anyone shed any light on how I can perform this procedure please?

FYI, I'm using a vLinker FD to link.

Just to add, I've tried several manual button dances that have been suggested online and none have worked.
