This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that measures the amount of electricity going into the battery from the charger. It's like the car is saying, 'Hey, something's wrong with how we're checking the battery's power!'
The P2D84 code is triggered when the vehicle's onboard computer (ECU) detects an unusually high signal from the input current sensor of the battery charger B. This sensor is responsible for monitoring the current flowing into the battery to ensure it's charging correctly.
The Battery Charger B Input Current Sensor Circuit High code indicates that the input current sensor for charger B is reporting a voltage or current reading that is higher than expected. This could be due to a malfunctioning sensor, wiring issues, or a problem with the charger itself.
• Battery not charging properly
• Warning light on the dashboard
• Possible reduced vehicle performance
• Faulty input current sensor
• Wiring issues or poor connections
• Malfunctioning battery charger
ECU: Engine Control Unit, the computer that manages engine functions.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Check for any loose or corroded connections in the wiring.
• Test the input current sensor for proper operation.
• Inspect the battery charger for any faults.
• Replace the faulty input current sensor.
• Repair or replace damaged wiring or connectors.
• Repair or replace the battery charger if necessary.

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect battery connections.
• Ensure proper maintenance of the charging system.
• Avoid overloading the vehicle's electrical system.
Sensor Issue
• Have the vehicle inspected by a professional if the warning light appears.
• Avoid using high-power electrical accessories until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on the charging system components.
This code is relatively uncommon and usually associated with specific vehicle models that have complex charging systems.
Moderate – While the vehicle may still be operable, it is important to address this issue to prevent battery charging problems.
Driving with a malfunctioning charging system can lead to battery failure and potential vehicle shutdown.
• Vehicle in 'ON' position
• Battery charger connected
The input current sensor is typically located near the battery or integrated into the charging system of the vehicle.
Q: Can I drive my car with this code?
A: It's possible to drive, but it's not recommended as it could lead to battery charging issues.
Q: How do I reset the code?
A: Fix the underlying issue and then use an OBD-II scanner to clear the code.
