2. If fluid is dark or smells burnt, drain and replace with appropriate transmission fluid.

3. Brake Inspection and Service

Tools Required: Jack, jack stands, lug wrench, brake cleaner
Raise the vehicle and remove the wheels:
1. Inspect brake pads for wear; replace if thinner than 3mm.
2. Check rotors for scoring or overheating; machine or replace if necessary.
3. Clean brake components with brake cleaner.

4. Electrical System Inspection

Tools Required: Multimeter
Inspect wiring harnesses and connectors:
1. Check for frayed wires or burnt connections.
2. Repair or replace damaged wiring as needed.

5. Exhaust System Inspection

Tools Required: Safety glasses, gloves
Inspect the exhaust system:
1. Look for holes, cracks, or signs of melting components.
2. Repair or replace any damaged sections of the exhaust system.
