Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, cleaning brush for battery terminals.
Ensure the vehicle is in 'Park' mode and the ignition is off.
Disconnect the negative terminal of the battery as a safety precaution.

2. Check and Replace the 12V Battery

Remove Battery Terminals
- Use a socket set to loosen the nut on the negative terminal and then remove the positive terminal.
Test Battery Voltage
- Connect the multimeter leads to the battery terminals; a healthy battery should read around 12.6V or higher.
- If the reading is below 12.4V, consider charging or replacing the battery.
Replace the Battery if Necessary
- If the battery is faulty, replace it with a compatible 12V battery (check the owner’s manual for specifications).
- Reconnect the positive terminal first, followed by the negative terminal.

3. Inspect and Clean Battery Terminals

Clean Terminals
- Inspect for corrosion; clean the terminals using a brush and a mixture of baking soda and water if necessary.
- Dry the terminals thoroughly.
Reconnect Terminals
- Ensure that both terminals are securely tightened.

4. Check and Replace Fuses

Locate the Fuse Box
- Find the fuse box (refer to the owner's manual for location).
Inspect Fuses
- Remove and check each fuse related to the starting system; replace any that are blown with the same amperage rating.

5. Test Ignition and Relays

Inspect Ignition Switch
- Use a multimeter to test for continuity when the ignition is turned to the start position.
- Replace the ignition switch if there is no continuity.
Check Relays
- Swap the starter relay with another relay of the same type in the fuse box to test functionality.
