1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe and level work environment.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminal connections (negative first, then positive).
2. Remove the battery from the vehicle using a socket set.
3. Inspect the battery for signs of damage or swelling. If defective, replace with a new battery that meets OEM specifications.
4. Reinstall the battery, connecting the positive terminal first, followed by the negative terminal.
Tools Required: Socket set, battery terminal cleaner.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor; typically found near the transmission bell housing.
2. Disconnect the wiring harness and battery cables from the starter motor.
3. Remove the starter motor from the mounting bracket using a socket set.
4. Test the starter motor by applying direct voltage from the battery. If it fails to engage, replace it with a new starter motor.
5. Install the new starter motor, ensuring all connections are secure and properly torqued.
Tools Required: Socket set, wrench set, multimeter.

4. Ignition Switch and Fuse Inspection

Sub-steps:
1. Inspect the ignition switch for wear or damage; replace if necessary.
