Code P0ACB 2015 GMC Sierra 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 difference between a single battery temperature sensor and an average of the other battery temperature sensors is greater than 25°C (45°F).
What are the Possible Causes of the DTC P0ACB 2015 GMC Sierra?
- Faulty Hybrid/EV Battery Assembly
- Hybrid/EV Battery Assembly harness is open or shorted
- Hybrid/EV Battery Assembly circuit poor electrical connection
- Faulty Hybrid/EV Battery Interface Control Module
