Some battery-monitor designs use more than one measurement path to support diagnostic checking. A disagreement can therefore describe a measurement-integrity issue rather than simply a low cell.
What to check next
Identify the reported diagnostic and compare the available measurements in the correct operating state. A specialist should assess the sensing connections and electronics before deciding whether the evidence points to the cell, monitor or supporting circuit.
Useful information for an enquiry
Provide the full scan and any channel-level measurements already obtained through approved diagnostics.
Not every battery system exposes the same checks. A semiconductor example explains the principle, not the exact architecture of every vehicle.
