Code B1516 2017 GMC Sierra Description

The Battery Current Sensor is a 3-wire hall effect current sensor. The Body Control Module (BCM) supplies 5 V and ground to the battery current sensor. The battery current sensor measures the amount of current flowing to or from the battery, and supplies a Pulse Width Modulation (PWM) signal to the BCM. The Diagnostic Trouble Code (DTC) will be set when the BCM detects a fault with the Battery Current Sensor.
