This code means that the car's computer has detected a problem with the part that tells you if the battery is charging properly. It's like the light that shows if your toy is charging isn't working right.
The vehicle's computer monitors the battery charger coupler status indicator. If the signal is lower than expected, it sets this code.
P0D87 indicates that the control circuit for the battery charger coupler status indicator is reporting a low voltage condition. This may be due to a fault in the wiring, a defective indicator, or a problem with the control module.
• Warning light on the dashboard
• Battery not charging properly
• Inability to determine charging status
• Faulty battery charger coupler status indicator
• Damaged wiring or connectors
• Malfunctioning control module
Battery Charger Coupler: The component that connects the charger to the vehicle's battery.
Control Circuit: The electrical pathway that manages the operation of a component.
• Check for any visible damage to the wiring or connectors.
• Test the battery charger coupler status indicator for proper operation.
• Use a multimeter to check for voltage at the control circuit.
• Repair or replace damaged wiring or connectors.

Electrical Circuit Issue
• Avoid using the vehicle until the issue is resolved.
• Consult a professional mechanic for diagnosis.
Check with your vehicle manufacturer for warranty coverage on electrical components.
This code has been more common with the rise of hybrid and electric vehicles, as they rely heavily on battery charging systems.
Moderate – It is important to address this issue to ensure the battery charges properly.
Driving with a malfunctioning charging system can lead to battery failure, which may leave you stranded.
• Vehicle in 'On' position
• Battery charger connected
The battery charger coupler is typically located near the vehicle's charging port.
Q: Can I drive my car with this code?
