Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Screwdrivers
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Identify and Repair Faulty Components

Sub-steps:
1. Locate the Source of Parasitic Draw: Reconnect the multimeter in series with the negative battery terminal and the battery cable to isolate the draw. Remove individual fuses one at a time to identify the circuit causing the draw.
2. Inspect and Repair the Faulty Circuit: Once the faulty circuit is identified, inspect the wiring and components connected to it for shorts, corrosion, or wear. Repair or replace any damaged components.
3. Reinstall Fuses: If any fuses were removed during testing, reinstall them once repairs are completed.

3. Battery Replacement (if necessary)

If the battery is found to be faulty or unable to hold a charge:
1. Remove the old battery by unbolting the battery hold-down clamp and disconnecting the positive terminal first, followed by the negative terminal.
2. Install the new battery in reverse order: connect the negative terminal first, then the positive terminal, and secure the battery with the hold-down clamp.

4. Reconnect Battery and Test

Reconnect the negative battery terminal and start the vehicle to ensure all systems are functioning correctly.
