Hi all, I am brand new so please be kind and gentle

It's not an HR-V but I cannot find a Jazz forum. My mother's 72 reg e:HEV Jazz was left undriven and for the 12V battery to go flat.
I had the RAC guy out who jump started it, monitored the battery and then decided it was toast so fitted a new one.

He plugged in his diagnostics and cleared "as many codes as [he] could" and told me the rest of them would go away when the systems aligned themselves, namely:
  • Steering angle sensor
  • All assist systems (lane departure, ACC, front assist
  • TPMS warning lit
  • Auto hold park brake doesn't work
  • Econ mode doesn't work
  • Cannot calibrate TPMS
After the new battery was fitted, I drove it 60 odd miles and the warnings didn't go away.
This morning I have pulled the battery for 5 minutes, reconnected it and driven 11 miles - still the same issue.

The car drives fine - steering assistance is fine, brakes work as they should, ABS works as it should - just all the other stuff that's not right.

Any thoughts?
