The voltage sensor integrated within the TagID module is reported as defective. This sensor provides critical voltage measurements for the battery management system (BMS) functionality and accurate state-of-charge calculations.
Click steps to track your progress.
Perform internal diagnostics on the TagID module, if available, to confirm the sensor failure.
Compare the voltage readings from the TagID with a direct multimeter measurement of the battery's actual voltage.
Consider replacement of the TagID module if the voltage sensor is integrated and not field-replaceable.
