Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the ignition is off.

2. Battery Inspection

Disconnect the negative terminal of the battery to prevent any electrical shorts.
Clean the battery terminals and cable ends using a wire brush.
Reconnect the battery and ensure the terminals are tight.

3. Starter Relay and Fuses

Locate the fuse box under the dash or hood.
Remove and visually inspect the starter relay; if damaged, replace it.
Check and replace any blown fuses related to the starting system.

4. Testing the Starter

Disconnect the wiring from the starter motor.
Use the multimeter to check voltage at the starter solenoid while a helper turns the key.
If voltage is present but the starter does not engage, replace the starter motor.

5. Reassembly

Reconnect all components in reverse order of disassembly.
Ensure all connections are secure.
Reconnect the battery terminals.
