This code means that the car's battery charger is not working properly. Sometimes it works, and sometimes it doesn't, like a light bulb that flickers on and off.
The P0D84 code indicates that there is an issue with the battery charger's input circuit, where the signal is not stable and is fluctuating.
The P0D84 code is triggered when the vehicle's onboard computer detects an intermittent or erratic signal from the battery charger input circuit. This could be due to wiring issues, a faulty charger, or other electrical problems affecting the circuit's stability.
• Battery not charging properly
• Warning light on the dashboard
• Vehicle may not start
• Loose or corroded wiring connections

Electrical Circuit Issue
• Have your vehicle checked by a professional if you notice charging issues.
• Avoid using high-power electrical accessories until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage related to electrical components.
This code has been reported in various hybrid and electric vehicles due to the complexity of their charging systems.
Moderate – It is important to address this issue to prevent battery failure and ensure the vehicle starts reliably.
Driving with a malfunctioning battery charger can lead to unexpected vehicle shutdowns, which may pose safety risks.
• Vehicle in 'ON' position
• Battery charger connected
The battery charger is typically located near the vehicle's battery or within the engine compartment.
Q: Can I drive my car with a P0D84 code?
A: It's not recommended to drive with this code active, as it can lead to battery drainage and potential vehicle shutdown.
Q: How can I prevent this issue from happening again?
A: Regular maintenance of the battery and charging system can help prevent this issue.
