This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that changes electricity from one type to another, and it's not working right. It's like when a toy needs batteries, but the battery compartment is broken.
The code B012A indicates an issue with the circuit for the DC/AC converter, specifically for the high voltage power outlet labeled 'D'. This could mean the circuit is open or not functioning correctly.
The DC/AC converter is responsible for converting direct current (DC) from the vehicle's battery into alternating current (AC) to power certain electrical components. An open circuit in the high voltage power outlet 'D' suggests a disconnection or break in the electrical pathway, preventing proper function.
• Power outlet not working
• Electrical devices not charging
• Warning light on dashboard
• Faulty DC/AC converter
• Broken or disconnected wiring
• Blown fuse in the circuit
DC: Direct Current
AC: Alternating Current
Converter: A device that changes electrical energy from one form to another
• Inspect the wiring and connections for damage or disconnection.
• Check the fuses related to the DC/AC converter circuit.
• Test the DC/AC converter for proper operation.
• Replace damaged wiring or connectors.
• Replace any blown fuses.
• Replace the DC/AC converter if it is faulty.
• Multimeter
• Wire stripper
• Screwdriver set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly check electrical connections.
• Avoid overloading power outlets.
• Inspect fuses periodically.
Electrical Circuit Issue
• Avoid using the affected power outlet until repaired.
• Consult a professional mechanic for diagnosis and repair.
Check vehicle warranty for coverage of electrical components.
This code has been reported in hybrid and electric vehicles due to their complex electrical systems.
Moderate – It should be addressed soon to avoid further electrical issues.
Operating a vehicle with electrical issues can lead to safety hazards. Ensure repairs are conducted by a qualified professional.
• Vehicle ignition on
• Power outlet in use
The DC/AC converter is typically located near the vehicle's battery or within the electrical distribution center.
Q: Can I still drive my car with this code?
A: Yes, but avoid using the affected power outlet until it's fixed.
Q: Will this issue drain my car battery?
A: It might if the circuit remains open, leading to a continuous power draw.
