Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and any necessary replacement parts.
Ensure the vehicle is parked in a safe area with the ignition off.
Disconnect the negative terminal of the 12V battery to prevent electrical shorts.

2. Inspect High-Voltage Battery Connections

Remove the cover or access panel for the high-voltage battery.
Visually inspect all connections for signs of corrosion or looseness.
Tighten any loose connections and clean corrosion using a wire brush and electrical cleaner.

3. Check the 12V Auxiliary Battery

Reconnect the negative terminal of the 12V battery.
Use a multimeter to measure the voltage of the 12V battery; it should read between 12.4V and 12.8V when fully charged.
If the voltage is below 12.4V, replace the battery.

4. Test the Charging System

With the vehicle in "Ready" mode, use the OBD-II scanner to monitor the charging system's performance.
Check for any discrepancies in charging voltage and current.
If the charging system is malfunctioning, consult the service manual for further diagnostics or component replacement.

5. Clear Fault Codes

After completing repairs, use the OBD-II scanner to clear the P0562 code from the vehicle's memory.
Monitor the vehicle's performance in subsequent tests to ensure the issue does not return.
