Solution

1. Preparation

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

2. Check and Replace Battery

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Remove the positive terminal and then the negative terminal from the battery.
3. Inspect the battery for any signs of damage or swelling.
4. If necessary, replace the battery with one that matches the specifications of the vehicle.
5. Reconnect the positive terminal first, then the negative terminal.

3. Inspect and Replace Starter Relay

Sub-steps:
1. Locate the fuse box and identify the starter relay.
2. Remove the starter relay and visually inspect it for any signs of damage.
3. If no visible damage is found, swap it with another relay of the same type in the fuse box.
4. Reinstall the relay and check if the vehicle starts.

4. Check and Clean Battery Terminals

Sub-steps:
1. Clean the battery terminals and cable ends using a mixture of baking soda and water to neutralize any corrosion.
2. Rinse with clean water and dry thoroughly.
3. Reconnect the terminals securely to ensure good contact.

5. Inspect and Test Starter Motor

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Check the wiring connection to the starter for any damage.
3. Use a multimeter to test for power at the starter terminal when the ignition is turned to the start position.
4. If no power is detected, trace wiring back to the ignition switch and relay.
5. If power is present but the starter does not engage, replace the starter motor.
