Code B1024 2016 GMC Sierra Description

The internal module circuitry temperature is monitored. If an over-heat condition that exceeds the maximum threshold of the internal circuitry or a malfunctioning temperature sensor is detected, the module will shut down until the internal circuitry cools. The Diagnostic Trouble Code (DTC) will be set when the module detects an over-heat condition or a malfunctioning sensor.
