1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean any corrosion on the battery terminals using a mixture of baking soda and water.
3. Tighten the battery terminals securely.
Tools Required: Wire brush, wrench set.

3. Starter Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box.
2. Remove the starter relay and visually inspect it for damage.
3. Swap it with another relay of the same type to test functionality.
Tools Required: Relay puller (optional).

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Inspect the wiring harness connected to the starter for any signs of damage or loose connections.
3. Using a multimeter, check for voltage at the starter terminal when the ignition is turned to the start position.
Tools Required: Multimeter, socket set.

5. Replace Battery or Starter (if necessary)

Sub-steps:
