Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

1.1. Disconnect the negative terminal of the battery first, followed by the positive terminal.
1.2. Clean any corrosion from the terminals using a wire brush and a solution of baking soda and water.
1.3. Tighten the battery terminal connections securely.

3. Battery Testing

2.1. Use a multimeter to measure the voltage across the battery terminals.
2.2. If the voltage is below 12.4 volts, recharge the battery or replace it if it cannot hold a charge.

4. Starter Motor Inspection

3.1. Locate the starter motor, typically found near the transmission.
3.2. Disconnect the electrical connectors from the starter.
3.3. Check the connections for tightness and inspect the wiring for damages.
3.4. If necessary, remove the starter motor (usually requires removing a couple of bolts) and test it separately.

5. Testing the Starter Relay

4.1. Locate the starter relay in the fuse box (consult the owner’s manual for the exact location).
4.2. Swap the relay with another identical relay in the fuse box to determine if the relay is faulty.
4.3. Replace the relay if it is found to be defective.
