Code P0C85 2016 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 hybrid battery temperature sensor is intermittent or has changed by 10°C (18°F) or greater for 4 out of 5 seconds.
What are the Possible Causes of the DTC P0C85 2016 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
