Solution

1. Preparation

Gather necessary tools and parts for repair.
Ensure the vehicle is in a safe location, and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection

Tools Required: Multimeter, wrench set, wire brush or battery cleaner.
Sub-steps:
1. Reconnect the battery to take a voltage reading. It should be above 12.4 volts for a healthy battery.
2. If the voltage is low, proceed to charge or replace the battery.
3. Clean battery terminals using a wire brush to remove corrosion.
4. Tighten the battery connections to ensure a secure fit.

3. Starter Relay and Motor Check

Tools Required: Multimeter, socket set.
Sub-steps:
1. Locate the starter relay in the fuse box; refer to the owner's manual for the exact location.
2. Swap the starter relay with another relay of the same type to test for functionality.
3. If the relay is functional, proceed to check the starter motor.
4. Disconnect the starter motor wiring and check for continuity using a multimeter.
5. If continuity is present, the starter may need replacement.

4. Final Steps

Reconnect all components and terminals securely.
Reconnect the negative battery terminal.
Test the vehicle to see if it starts.
