Solution

1. Preparation

Gather tools: Multimeter, socket set, battery terminal cleaner, safety gloves, and safety glasses.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect Battery
- Use a socket set to disconnect the negative battery terminal first, followed by the positive terminal.
Clean Battery Terminals
- Use a battery terminal cleaner to remove corrosion from battery terminals.
- Ensure both terminals are clean and free of debris.
Test and Replace Battery
- Use a multimeter to check the voltage. If below 12.4 volts, replace the battery.
- If replacing, carefully remove the old battery and install the new one, connecting the positive terminal first, followed by the negative.

3. Starter Motor Inspection

Locate Starter Motor
- Refer to the vehicle's manual for the exact location of the starter motor.
Check Connections
- Inspect the wiring and connections to the starter motor for any loose connections or damage.
Test Starter Motor
- Use a multimeter to check for voltage at the starter terminal while attempting to start the vehicle.
- If there is no voltage, replace the starter motor.

4. Check Relay and Ignition Switch

Inspect Starter Relay
- Locate the starter relay in the fuse box and swap with a similar relay to test functionality.
Test Ignition Switch
- Use a multimeter to ensure continuity when the key is turned to the start position. Replace if faulty.
