That indicates the OFF switch isn't really an off switch at all, if voltage monitoring remains active.
Since many electronic stuff has an electronic "Toggle" action to change it's state from ON to OFF or OFF to ON, then it is possible a small voltage fluctuation may toggle the switched state of some auxiliary items like scan gauge and make it switch on.
I know in a Dmax, sometimes, not always, when the key unlock is activated the ScanGauge lights up and the only situation which changed is the central locking was operated. Mine does exactly that, sometimes.
Any fridge, on off, or some vehicle systems periodic electronic
check pulse may also possibly activate the scan Gauge.
On board cameras toggle, (switch on) when the power is connected ie key on.
