Toaf Airbag faults

[STUBIE]

So I have managed to get a TOAF scan of my ongoing airbag light issue and its giving the following faults;

9144 Side Sensor Right: Communication Error
9142 Side Sensor Right: Plausibility Error
9001 Supply Voltage: Low voltage
9036 Ignition Circuit (SideBag Front Seat Left) :Resistance too high
9016 Ignition Circuit (Belt Pretensioner Left) : Resistance too high

So am i right in thinking I have 2 issues to resolve,
One the passenger seat, both the airbag and tensioner connections which I have taken apart and cleaned a good few times
Secondly the drivers side side impact sensor which I will need to check connection or replace.

Not to sure of the Low voltage error but I did just put the battery back on after it went flat checking the airbag light after twiddling

Any assistance most gratefully received
