This summary uses the existing diagnostic information shown in full below.
This code means there is a problem with the car's system that tells you how much the battery is charged. It's like when a toy's battery light doesn't work right.
The P0E41 code indicates a low voltage condition in the control circuit for the Charge Status Indicator B.
The Charge Status Indicator B Control Circuit is responsible for monitoring and reporting the charge level of the vehicle's battery. A 'low' condition means that the voltage in the circuit is below the expected range, which could be due to wiring issues, a faulty sensor, or a failing battery management system.

This code has been reported in hybrid and electric vehicles, often related to sensor or wiring issues.
Moderate – It should be addressed soon to avoid battery charging problems.
Ignoring this issue may lead to battery performance problems, which can affect vehicle reliability.
• Vehicle in 'ON' position
• Battery fully charged
The charge status indicator sensor is typically located near the vehicle's battery or integrated into the battery management system.
