Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the engine off.
Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the negative and positive battery terminals using a socket set.
2. Clean the terminals and battery posts with a wire brush and terminal cleaner to remove corrosion.
3. Reconnect the positive terminal first, followed by the negative terminal.

3. Replace Battery (if necessary)

Sub-steps:
1. If the battery test indicates failure, remove the battery hold-down bracket using a socket set.
2. Carefully lift the old battery out of the vehicle.
3. Place the new battery in the battery tray, ensuring it is secure.
4. Reinstall the hold-down bracket and tighten to manufacturer specifications.
5. Reconnect the battery terminals (positive first, then negative).

4. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect the wiring harness leading to the battery management system for signs of wear or damage.
2. Disconnect and reconnect any connectors to ensure a secure fit.
3. Replace any damaged wiring or connectors as needed.

5. Clear Fault Codes

Sub-steps:
1. Use the OBD-II scanner to clear the B10D1 code from the vehicle’s ECU.
2. Start the engine and check for the reoccurrence of the code.
