• Power outlet not working
• Warning light on the dashboard
• Inability to use electrical devices plugged into the outlet
• Faulty DC/AC converter
• Damaged wiring or connectors
• Blown fuse in the power outlet circuit
DC: Direct Current
AC: Alternating Current
Converter: A device that changes electrical energy from one form to another
• B012A
• B012C
This code means there's a problem with the car's power outlet system. It's like when a plug in your house doesn't work because the wire is broken or not connected.
The code indicates an issue with the circuit related to the DC/AC converter's high voltage power outlet, specifically outlet 'E'. This could mean the circuit is open or not functioning correctly.
The B012B code is set when the vehicle's control module detects an open circuit or malfunction in the high voltage power outlet 'E' of the DC/AC converter. This converter is responsible for converting direct current (DC) from the vehicle's battery to alternating current (AC) for use in various electrical components.
• Check the fuse related to the power outlet circuit.
• Inspect wiring and connectors for damage or disconnection.
• Test the DC/AC converter for proper operation.
• Replace the blown fuse.
• Repair or replace damaged wiring or connectors.
• Replace the faulty DC/AC converter.
• Multimeter
• Screwdriver set
• Wire repair kit

Electrical Circuit Issue
• Avoid using the affected power outlet until repaired.
• Consult a professional mechanic for diagnosis.
• Check vehicle warranty for coverage.
Repairs may be covered under the vehicle's electrical system warranty. Check with the manufacturer or dealer.
This code has been associated with vehicles using advanced electrical systems, particularly hybrids and electric vehicles, due to their reliance on DC/AC converters.
Moderate – While the vehicle can still be driven, electrical components relying on the outlet may not function.
Ensure all repairs are conducted by a qualified professional to avoid electrical hazards.
• Vehicle ignition in the ON position.
• Power outlet in use or tested with a compatible device.
The DC/AC converter is typically located near the vehicle's battery or electrical distribution center.
Q: Can I still drive my car with this code?
A: Yes, but the affected power outlet may not work, so avoid using it until repaired.
Q: Is this a common issue?
A: It's more common in vehicles with advanced electrical systems, such as hybrids and electric cars.
