Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, battery load tester, socket set, and wrench set.
Safety warning: Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Battery Replacement (if needed)

Locate the battery under the hood.
Remove Battery:
1. Disconnect the negative terminal first, then the positive terminal.
2. Unbolt the battery hold-down bracket and carefully remove the battery from the tray.
Install New Battery:
1. Place the new battery in the tray ensuring proper orientation.
2. Secure the battery with the hold-down bracket.
3. Connect the positive terminal first, followed by the negative terminal.
4. Ensure all connections are tight.

3. Starter Motor Inspection (if battery is fine)

Remove Starter Motor:
1. Disconnect the battery (if not already done).
2. Locate the starter motor, usually near the transmission.
3. Remove any protective covers if necessary.
4. Unplug the electrical connector from the starter.
5. Remove the mounting bolts securing the starter to the engine.
Test Starter Motor:
1. Use a multimeter to check for voltage at the starter terminal when the ignition is turned on.
2. If voltage is present but the starter does not engage, it needs replacement.
Install New Starter Motor (if needed):
1. Position the new starter in place and secure it with mounting bolts to the engine.
2. Reconnect the electrical connector.
3. Recheck all connections.
