The charger was unable to write data to the TagID module. This prevents the charger from storing updated information or configuration settings (e.g., charge cycles, maintenance data) on the battery's identifier.
Click steps to track your progress.
Check the TagID module for any physical switches or software settings that might enable write-protection and disable them.
Verify the TagID's memory health using diagnostic tools to identify any defective memory sectors.
Inspect the CAN bus connection and wiring, then retry the data write operation.
