Solution

1. Preparation

Gather necessary tools: multimeter, socket set, battery terminal cleaner, wrench, and safety gloves.
Ensure the vehicle is parked in a safe, level area with the ignition turned off.

2. Battery Terminal Inspection

Sub-step 1: Disconnect the negative battery terminal using a wrench. Always remove the negative terminal first to prevent short circuits.
Sub-step 2: Disconnect the positive battery terminal in the same manner.
Sub-step 3: Clean the battery terminals and cable connectors with a battery terminal cleaner to remove any corrosion.

3. Battery Replacement (if necessary)

Sub-step 1: If the battery voltage is below 12.4 volts or the load test fails, remove the old battery. Use a socket set to unscrew any retaining brackets.
Sub-step 2: Install the new battery in the reverse order, ensuring it is securely mounted.
Sub-step 3: Reconnect the positive terminal first, followed by the negative terminal.

4. System Reset

Sub-step 1: With the new battery installed, turn on the ignition without starting the engine. This will reset any electronic systems.
Sub-step 2: Start the engine to ensure proper function.
