Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the battery to ensure safety before starting any repairs.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cables, starting with the negative terminal.
2. Clean the terminals using a wire brush and baking soda solution if corrosion is present.
3. If the battery voltage is below 12.4 volts, recharge or replace the battery with a new one (ensure it meets manufacturer's specifications).
4. Reconnect the battery terminals securely.

3. Starter Motor and Relay Inspection

Sub-steps:
1. Locate the starter motor, typically found near the engine's bottom.
2. Check the wiring and connections to the starter motor for damage or loosening.
3. Remove the starter motor if testing is required; use a wrench to unbolt it.
4. Test the starter motor using a bench test method, connecting it directly to the battery.
5. Replace the starter motor if it fails the test.

4. Replace Relay (if necessary)

Sub-steps:
1. Identify the starter relay in the fuse box diagram.
2. Remove the faulty relay and replace it with a new one of the same specifications.
3. Recheck all connections before attempting to start the vehicle.
