Solution

1. Preparation

Tools Needed: Socket set, multimeter, battery terminal cleaner, OBD-II scanner.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection and Testing

Clean battery terminals using a terminal cleaner to remove corrosion.
Reconnect the terminals securely and ensure they are tight.
Use the multimeter to measure the battery voltage; if below 12.4 volts, charge or replace the battery.

3. Starter and Solenoid Inspection

Locate the starter motor; it is typically mounted on the engine block.
Check the wiring harness connected to the starter for any signs of wear or disconnection.
Use a wrench to remove the starter motor's electrical connections, ensuring no dirt or corrosion is present.
If necessary, replace the starter motor if it shows signs of failure (e.g., burnt smell or physical damage).

4. Relay and Fuse Check

Locate the fuse box and check the starter relay and associated fuses for continuity.
Replace any blown fuses and ensure the starter relay clicks when power is applied.
