Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, ammeter, socket set, battery terminal cleaner, safety gloves.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Replacement (If Needed)

Sub-steps:
1. Remove the battery terminal clamps (negative first, then positive).
2. Unscrew and remove the battery hold-down clamp.
3. Carefully lift the old battery out of the vehicle and place it in a safe location.
4. Install the new battery in reverse order: place it in the battery tray, secure the hold-down clamp, and connect the positive terminal first followed by the negative terminal.

3. Address Parasitic Draw (If Detected)

Sub-steps:
1. Identify the circuit causing the draw using the ammeter readings.
2. Disconnect fuses one at a time while monitoring the ammeter until the draw drops to an acceptable level.
3. Inspect and repair or replace the component associated with the circuit that caused the excessive draw.

4. Clean Battery Terminals

Sub-steps:
1. Use a battery terminal cleaner to remove any corrosion from the battery terminals.
2. Reattach the terminals securely and ensure a tight fit.
