Abstract
A diagnostic system for a vehicle includes a traction battery including a plurality of cells, and a controller configured to indicate an overcurrent condition in response to battery current being greater than a value of an upper limit of a current sensor and a difference between a measured battery voltage and an estimated battery voltage, that is based on the value, being greater than a threshold.
