Solution

1. Preparation

Tools Required: Torque wrench, socket set, multimeter
Ensure the vehicle is in "Park" mode and on a flat surface.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect Electrical Components

Sub-steps:
1. Remove the access panel to the battery compartment.
2. Visually inspect all electrical connections for corrosion or loose fittings.
3. Tighten any loose connections to ensure proper contact.
4. If corrosion is found, clean the terminals with a wire brush and apply dielectric grease.

3. Check Cooling System

Sub-steps:
1. Inspect the coolant lines for any signs of leaks or damage.
2. Verify that the cooling fans are operational by manually activating them from the vehicle interface.
3. If fans are not functioning, check the fan fuses and replace any that are blown.

4. Evaluate Battery Management System

Sub-steps:
1. Reconnect the 12V battery.
2. Use a multimeter to check the voltage levels of the battery packs.
3. If voltage is low, consider recharging or replacing the battery pack.

5. Reassemble and Test

Sub-steps:
1. Reattach all access panels securely.
2. Perform a soft reset of the vehicle by holding down both scroll wheels on the steering wheel until the screen refreshes.
3. Monitor the vehicle for any abnormal noises during the next park cycle.
