Jazz Hybrid - 2021 - No communication with IMA
 

I have a Hybrid Jazz 2021 which needed a new HV battery I was told by the dealership. The car has no warranty due to a engine change by previous owner.

I replaced the HV battery and it showed 7 bars.
I let it idle for few minutes and then started to reverse it where the HV battery went down from 7 to 0 bars. Then the car stalled.
The car will try and start for a few seconds if I try but then stalls.

After replacing the HV battery do I need to program anything or is it a plug and play after connecting it back up?

I have connected the HDS diagnostics and cleared the errors it was bringing up: P06af.

In the diagnostics when I try and go to the IMA/Powertrain section it says "No communication with IMA" which I think may be the issue?
Or am I getting that due to the HV battery going too low?

Any suggestions and ideas please.
