OBD-II scanner
Jumper cables

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery using a socket wrench.
Sub-step 2: Clean the battery terminals with a wire brush to remove any corrosion.
Sub-step 3: Reconnect the battery and ensure the terminals are tight.

3. Starter Motor Check

Sub-step 1: Locate the starter motor, typically found near the transmission.
Sub-step 2: Disconnect electrical connectors from the starter motor.
Sub-step 3: Use the multimeter to check for voltage at the starter motor terminal while a helper turns the key to the start position.
Sub-step 4: If there is voltage but the starter does not engage, replace the starter motor.

4. Relay and Fuse Inspection

Sub-step 1: Locate the fuse box and identify the starter relay.
