Code P0AEB 2015 Chevrolet Silverado Description
Each Hybrid/EV Battery Interface Control Module communicates the temperature sensor values to the Hybrid/EV Powertrain Control Module via serial data.
The Hybrid/EV Powertrain Control Module uses the battery temperature sensors to determine the Hybrid/EV Battery Module temperature in order to control the battery cooling system operation.
The Diagnostic Trouble Code (DTC) will be set when the hybrid battery temperature sensor is less than -69°C (-92°F).
