Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during inspection and repairs.

2. Inspect and Clean Brake Components

Tools Required: Jack and jack stands, lug wrench, brake cleaner.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads and rotors for signs of wear or overheating. Replace components if they are excessively worn or damaged.
Clean the brake assembly with brake cleaner to remove any debris or contaminants.

3. Check Engine Components

Tools Required: Socket set, torque wrench, engine oil, coolant.
Inspect the engine oil level using the dipstick; top off or change if low or dirty.
Check the coolant level in the reservoir; refill if necessary.
Look for any oil leaks around gaskets and seals; replace any faulty gaskets as needed.

4. Evaluate Electrical System

Tools Required: Multimeter, electrical cleaner.
Inspect wiring harnesses and connectors for signs of damage or overheating.
Use a multimeter to test the voltage and ensure all electrical components are functioning correctly.
Clean any corroded electrical contacts with electrical cleaner to ensure good connections.
