Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper cables.
Disconnect the negative battery terminal to avoid electrical shorts.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion on the terminals and cable ends using a wire brush.
Reconnect the terminals securely (positive first, then negative).
Test the battery voltage again; if below 12.6 volts, consider a jump-start or battery replacement.

3. Starter Relay and Fuse Check

Locate the fuse box and identify the starter fuse and relay as specified in the owner’s manual.
Remove the starter fuse and inspect it; replace if blown.
Swap the starter relay with a similar relay from another system (e.g., horn) to test functionality.

4. Starter Motor Inspection

If the battery and fuses are functional, locate the starter motor.
Remove any necessary components for access (e.g., air intake duct).
Check connections to the starter motor; clean and tighten as necessary.
Test the starter motor by applying direct battery voltage using jumper cables; replace if it does not engage.

5. Final Assembly

Reinstall any components removed during the process.
Reconnect the battery terminals securely.
Ensure all tools and materials are removed from the engine bay.
