1. Preparation

Tools Required: OBD-II scanner, socket set, inspection mirror, flashlight, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspection.

2. Fluid Replacement

If low or burnt fluid is found:
1. Drain the fluid: Use a fluid catch pan to collect any leaking or burnt fluid.
2. Replace with new fluid: Consult the owner's manual for the correct type and quantity of fluid.
3. Check for leaks: Ensure that all seals and gaskets are intact after replacement.

3. Component Inspection and Replacement

If any damaged components are located:
1. Remove affected parts: For belts, use a socket wrench to loosen and remove the tensioner.
2. Replace with new parts: Install new belts or hoses, ensuring proper routing and tension.
3. Reconnect any electrical connectors and ensure all connections are secure.

4. Brake System Check

If brakes are suspected:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect brake pads and rotors for excessive wear or glazing.
3. Replace worn components: Install new brake pads or rotors as necessary, following torque specifications for caliper bolts.
