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 form to another, like when you plug in a phone charger. It's not working right.
The code indicates an issue with the circuit for the DC/AC converter, which is responsible for converting direct current (DC) to alternating current (AC) for power outlets in the vehicle.
The B0127 code is set when the vehicle's control module detects an open or malfunction in the circuit of the DC/AC converter responsible for powering high voltage outlets. This can affect the functionality of power outlets used for charging or powering devices.
• Power outlets not functioning
• Warning light on the dashboard
• Inability to charge devices using car outlets
• Faulty DC/AC converter
• Open or shorted wiring in the circuit
• Blown fuse related to the power outlet circuit
DC: Direct Current
AC: Alternating Current
Converter: A device that changes electrical energy from one form to another
• Check the fuse related to the power outlet circuit.
• Inspect wiring and connections for damage or disconnection.
• Test the DC/AC converter for proper operation.
• Replace any blown fuses.
• Repair or replace damaged wiring.
• Replace the faulty DC/AC converter if necessary.
• Multimeter
• Fuse puller
• Screwdriver set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly check and replace fuses as needed.
• Avoid overloading power outlets.
• Perform routine inspections of electrical systems.
Electrical Circuit Issue
• Avoid using the affected power outlet until repaired.
• Consult a professional mechanic for diagnosis and repair.
Check with your vehicle manufacturer for warranty coverage on electrical components.
This code has been associated with issues in hybrid and electric vehicles where high voltage systems are more prevalent.
Moderate – While not critical, it should be addressed to restore functionality to vehicle power outlets.
Ensure all repairs are conducted by a qualified technician to prevent electrical hazards.
• Vehicle ignition in the ON position.
• Power outlet in use or tested with a device.
The DC/AC converter is typically located near the vehicle's power distribution center or under the dashboard.
Q: Can I still drive my car with this code?
A: Yes, you can drive your car, but the power outlets may not work until the issue is fixed.
Q: Will this issue drain my car battery?
A: It's unlikely to drain the battery, but it's best to fix the issue to ensure all systems are working properly.
