This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected that the electric motor is using too much electricity in one of its parts, which might cause problems if not fixed.
The code P2C71 is triggered when the vehicle's control module detects a higher than normal current in the Phase Z of Drive Motor 'A'.
The drive motor in an electric or hybrid vehicle is divided into phases, labeled as X, Y, and Z. Each phase carries electrical current to power the motor. If the current in Phase Z is too high, it can indicate an electrical fault such as a short circuit or a problem with the motor's control system.
• Reduced vehicle performance
• Warning light on the dashboard
• Unusual noises from the motor
• Short circuit in the motor winding
• Faulty motor control module
• Damaged wiring or connectors
Drive Motor: An electric motor that powers the vehicle.
Phase: A division of the electrical power supply to the motor.
• Check for any error codes related to the motor control system.
• Inspect the wiring and connectors for damage or corrosion.
• Test the motor phase currents with a multimeter.
• Repair or replace damaged wiring or connectors.
• Replace the motor control module if found faulty.
• Inspect and repair the motor winding if necessary.
• OBD-II scanner
• Multimeter
• Insulation resistance tester

Difficult
• Tesla Model S
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks on the electrical system.
• Avoid driving through deep water to prevent electrical shorts.
• Ensure proper cooling of the motor and its components.
Electrical System Issue
• Do not drive the vehicle until the issue is resolved to avoid further damage.
• Consult with a certified electric vehicle technician.
Check with the vehicle manufacturer; electric motor components may be covered under warranty.
This code is relatively new and primarily affects electric and hybrid vehicles as they become more prevalent.
High – Immediate attention is required to prevent potential damage to the motor.
Driving with this code active may lead to vehicle breakdown and poses a safety risk.
• Vehicle must be in 'Ready' mode.
• Ensure the battery is fully charged.
The drive motor is typically located in the engine bay or near the axle in electric vehicles.
Q: Can I drive with this code?
A: It's not recommended to drive with this code active as it can lead to further damage.
Q: Is this a common issue?
A: This issue is not very common but can occur in electric and hybrid vehicles.
