Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
• Safety Warnings: Disconnect the battery before working on electrical systems and ensure the vehicle is on a flat surface.

2. Battery Maintenance

• Step 1: Disconnect the negative terminal from the battery.
• Step 2: Clean the battery terminals and cable connections using a terminal cleaner to remove corrosion.
