Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper wires, wrench set
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Check and Replacement

Inspect Battery:
- Assess for corrosion on terminals; clean if necessary using a mixture of baking soda and water.
Test Battery Voltage:
- Connect a multimeter to the battery terminals; if voltage is below 12.4 volts, proceed to jump-start or replace the battery.
Replace Battery (if needed):
- Remove the battery hold-down bracket using a socket set.
- Disconnect positive terminal first, followed by the negative terminal.
- Replace with a new battery, ensuring proper terminal connection (positive first).

3. Starter Motor Inspection

Check Connections:
- Inspect all connections at the starter motor for looseness or corrosion.
Test Starter Motor:
- Use jumper wires to bypass the ignition switch and directly supply power to the starter motor. If it cranks, replace the ignition switch; if not, replace the starter motor.

4. Relay and Fuse Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box; test for continuity using a multimeter.
- Replace if defective.
Inspect Fuses:
- Pull each fuse related to the starting system and visually check or test with a multimeter. Replace any blown fuses.
