Solution

1. Preparation

Gather tools: multimeter, battery tester, jumper cables, socket set.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery cable if planning to remove the battery.

2. Clean Battery Terminals

Sub-steps:
1. Use a wire brush to clean any corrosion from the battery terminals and cable ends.
2. Ensure connections are tight and secure before reconnecting.

3. Replace Battery (if necessary)

Sub-steps:
1. Use a socket set to remove the battery hold-down bracket.
2. Carefully lift the battery out of the tray.
3. Place the new battery in the tray, ensuring it is oriented correctly.
4. Reattach the hold-down bracket and tighten to manufacturer specifications.
5. Connect the positive terminal first, then the negative terminal.

4. Test Electrical Systems

Sub-steps:
1. Reconnect the negative battery cable securely.
2. Turn on the ignition and verify all electrical systems are functioning (lights, windows, dashboard indicators).
3. Attempt to start the engine.
