Solution

1. Preparation

Ensure the vehicle is parked safely, with the parking brake engaged.
Gather tools: multimeter, socket set, and cleaning supplies for terminals.

2. Check and Replace the 12V Battery

Remove 12V Battery Terminal Connections
- Disconnect the negative terminal first, followed by the positive terminal.
- Use a socket set to loosen the terminal bolts.
Inspect Battery Condition
- Check for signs of corrosion on the terminals and cables.
- Clean terminals with a mixture of baking soda and water if corrosion is present.
Test Battery Voltage
- Connect the multimeter leads to the battery terminals.
- Ensure voltage reads above 12.4V; if below, the battery may need replacement.
Replace Battery (if necessary)
- If the battery is faulty, replace it with a new 12V battery that meets manufacturer specifications.
- Reconnect terminals: positive first, then negative, ensuring tight connections.

3. Check Main Battery Connections

Inspect Main Battery Connectors
- Locate the main battery connection points and inspect for secure fittings.
- Ensure no debris or damage is present on connectors.
Check Fuses
- Identify the fuse box and check for blown fuses related to the starting system.
- Replace any blown fuses with the correct amperage.

4. Test the Start/Stop Button

Examine the Start Button Functionality
- Ensure the button is not stuck and is functioning properly.
- If malfunctioning, consider replacing or repairing the button.
