Solution

1. Preparation

Ensure the vehicle is in park (or neutral if manual transmission).
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Replacement (if necessary)

Remove the negative battery cable first, followed by the positive cable.
Unscrew and remove the battery hold-down clamp.
Carefully lift the battery out of the tray.
Place the new battery in the tray, ensuring proper orientation.
Secure the battery with the hold-down clamp.
Connect the positive battery cable first, then the negative cable.

3. Starter Motor Replacement (if necessary)

Locate the starter motor (typically near the transmission).
Disconnect the negative battery cable if not already done.
Remove the electrical connectors from the starter solenoid.
Unscrew the mounting bolts holding the starter motor in place.
Carefully remove the starter motor from its position.
Install the new starter motor by reversing the removal steps.
Ensure all connections are tight and secure.

4. Final Checks

Reconnect the negative battery cable.
Ensure all tools and debris are removed from the engine bay.
Start the vehicle to confirm the issue is resolved.
