2. Battery Check

Sub-steps:
1. Reconnect the battery if previously disconnected.
2. Clean battery terminals with a wire brush to remove corrosion.
3. Tighten battery connections.
Tools Required: Wire brush, wrench set

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, typically found near the base of the engine near the transmission.
2. Disconnect the wiring harness from the starter.
3. Using a multimeter, check for voltage at the starter solenoid while attempting to start the vehicle.
4. If voltage is present and the starter does not engage, replace the starter motor.
