Solution

1. Preparation

Gather tools: Multimeter, socket set, battery terminal cleaner, OBD-II scanner, torque wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect the negative battery terminal using a socket wrench.
Clean the battery terminals with a battery terminal cleaner to remove corrosion.
Reconnect the battery terminals securely. If the battery voltage is low (below 12.4 volts), proceed to replace the battery.
Remove the old battery by loosening the hold-down bracket and lifting it out.
Install the new battery, ensuring correct polarity, and tighten the hold-down bracket.
Reconnect the negative terminal first, then the positive terminal.

3. Starter Relay and Fuse Check

Locate the fuse box under the hood and identify the starter relay and fuses related to the starting system.
Remove the starter relay and visually inspect for any damage; replace if necessary.
Check the corresponding fuse for continuity using a multimeter; replace if blown.

4. Starter Motor Inspection

If problems persist, locate the starter motor, typically found near the bottom of the engine near the transmission.
Disconnect the wiring harness from the starter motor.
Remove the starter motor by unscrewing the mounting bolts (usually two or three) and sliding it out.
Test the starter motor by connecting it directly to the battery using jumper cables to see if it spins.
If the starter motor does not engage, replace it with a new or refurbished unit.
