This summary uses the existing diagnostic information shown in full below.
This code means that the car's air conditioning system is having trouble because too much electricity is going through one part of the motor that helps cool the car.
The code indicates that the current in the U phase of the A/C compressor motor is higher than expected, which could lead to overheating or damage.
The A/C compressor motor uses three phases (U, V, W) to operate efficiently. If the current in the U phase is too high, it can indicate an electrical fault or overload condition, potentially leading to motor failure.
• A/C not cooling effectively
• Unusual noises from the A/C system
• Warning light on the dashboard
• Faulty A/C compressor motor
• Short circuit in the wiring
• Defective motor control module
A/C: Air Conditioning
Compressor: A component that compresses refrigerant and circulates it through the A/C system
• Check for any stored codes and freeze frame data.
• Inspect the A/C compressor motor and wiring for damage.
• Test the motor control module for proper operation.
• Replace the faulty A/C compressor motor.
• Repair or replace damaged wiring.
• Replace the motor control module if defective.
• OBD-II scanner
• Multimeter
• Wiring diagram

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance of the A/C system
• Inspect wiring for wear and tear
• Ensure proper operation of electrical components
Electrical Issue
• Avoid using the A/C until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been associated with hybrid and electric vehicles due to their complex electrical systems.
Moderate – It is advisable to address this issue soon to avoid further damage to the A/C system.
Ignoring this code could lead to A/C system failure, which may affect comfort and safety during driving.
• Vehicle in a safe, stationary position
• A/C system activated
The A/C compressor motor is typically located in the engine compartment, connected to the A/C system.
Q: Can I still drive my car with this code?
A: Yes, but it is recommended to avoid using the A/C until the issue is fixed to prevent further damage.
Q: Will fixing this code improve my A/C performance?
A: Yes, resolving the issue should restore proper A/C function.
