This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the battery in a hybrid or electric vehicle. It's like when your toy's battery isn't working right and it can't power the toy properly.
The vehicle's control module has detected an issue with the internal isolation of the hybrid or electric vehicle's battery voltage system.
The P2C86 code indicates that the vehicle's control system has identified a fault in the internal isolation of the hybrid or electric vehicle's battery voltage. This could mean that the insulation that keeps the battery's electrical system safe and separate from the vehicle's body or other components is compromised.
• Warning light on the dashboard
• Reduced vehicle performance
• Inability to charge the battery
• Damaged or degraded battery insulation
• Faulty battery management system
• Corrosion or moisture in battery connections
Hybrid: A vehicle that uses both an internal combustion engine and an electric motor.
EV: Electric Vehicle, a car powered entirely by electricity.
• Perform a visual inspection of the battery and its connections.
• Use a diagnostic tool to check for additional codes.
• Test the battery insulation resistance.
• Replace damaged battery insulation.
• Repair or replace the battery management system.
• Clean and secure battery connections.

• Regularly inspect battery connections.
• Keep battery compartment dry and clean.
• Schedule routine maintenance checks.
Electrical System Issue
• Avoid driving the vehicle until the issue is resolved.
• Consult with a certified hybrid/EV technician.
• Regularly monitor the vehicle's battery health.
Check if the battery or electrical system is still under warranty, as many manufacturers offer extended warranties for hybrid/EV components.
This code has become more common with the increased use of hybrid and electric vehicles, highlighting the importance of proper battery maintenance.
High – This issue can lead to safety hazards and should be addressed immediately.
Driving with this code may lead to vehicle malfunction or safety hazards. It is advised to seek professional assistance promptly.
• Vehicle in 'ON' mode
• Battery fully charged
The hybrid/EV battery is typically located beneath the vehicle floor or in the trunk area.
