Code P0C35 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 hybrid battery temperature sensor is greater than 160°C (320°F).
What are the Possible Causes of the DTC P0C35 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
How to Fix the DTC P0C35 2015 GMC Sierra?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0C35 2015 GMC Sierra code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

2. What are the symptoms of code P0C35 in a 2015 GMC Sierra?
Common symptoms include an illuminated check engine light, reduced hybrid/EV performance, limited battery charging or discharging capabilities, or activation of limp mode.
3. What causes the P0C35 code to appear on a 2015 GMC Sierra?
The code can be caused by a faulty battery temperature sensor, damaged or corroded wiring, poor electrical connections, or a malfunctioning battery management system.
4. Can driving with code P0C35 damage my 2015 GMC Sierra?
Continuing to drive with this code could lead to improper battery management, reduced efficiency, or potential damage to the hybrid/EV battery system over time.
5. How do I diagnose the P0C35 code on a 2015 GMC Sierra?
Diagnose the issue by inspecting the temperature sensor wiring and connectors for damage, testing the sensor's resistance, and using a scan tool to monitor live data for the battery temperature sensor.
6. How can I fix the P0C35 code on my 2015 GMC Sierra?
Repairs may include replacing the faulty battery temperature sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the battery management system.
7. How much does it cost to fix the P0C35 code on a 2015 GMC Sierra?
The cost can vary depending on the issue. Replacing a temperature sensor may cost $100–$300, while wiring repairs or additional diagnostics could increase the cost.
8. Is the P0C35 code specific to sensor 6 on the hybrid/EV battery?
Yes, P0C35 specifically refers to the temperature sensor for module 6 of the hybrid/EV battery pack, indicating a low voltage signal from that sensor.
9. Can a low hybrid battery charge cause the P0C35 code?
A low battery charge itself is unlikely to cause this code, but improper sensor readings due to wiring or sensor issues could affect the battery's performance and trigger P0C35.
10. Do I need special tools to repair the P0C35 code on my 2015 GMC Sierra?
Yes, specialized tools like a scan tool capable of reading hybrid/EV fault codes and monitoring live data, as well as a multimeter for electrical testing, are typically required.
