Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, and wire brush.
Ensure the vehicle is in a safe environment with the transmission in park or neutral.

2. Battery Check and Replacement

Check Battery Voltage
- Disconnect the battery negative terminal.
- Use a multimeter to measure the voltage; if below 12.4 volts, charge or replace the battery.
Clean Battery Terminals
- Use a wire brush to clean any corrosion from the battery terminals and cable connectors.
- Reconnect the terminals securely.

3. Starter System Inspection

Test Starter
- Locate the starter motor (usually near the transmission).
- Disconnect the starter wiring harness.
- Use jumper cables to connect the starter directly to the battery; it should engage and spin.
Replace Starter (if necessary)
- If the starter does not engage, remove it by unscrewing the mounting bolts and disconnecting the wiring.
- Install the new starter and connect the wiring harness, ensuring secure connections.

4. Fuse and Relay Check

Inspect Fuses
- Locate the fuse box and check the fuses related to the starting system (refer to the owner's manual).
- Replace any blown fuses with the correct amperage.
Check Starter Relay
- Locate the starter relay in the fuse box and test it for continuity.
- Replace if it is faulty.
