Advanced Diagnostic Techniques

For tricky diagnoses, combine tools. If the OBD Scanner gives a generic engine code, follow up with a Compression Tester or Fuel Pressure Tester to narrow down the issue. For suspension noises, use the Test Path to pinpoint the exact wheel, then visually inspect components for wear or damage. check fluid levels and for leaks, as these are often overlooked. Sometimes, simply removing a part and inspecting its condition (hovering over it) can reveal the problem without needing a specialized tool. Trust your instincts and methodical approach.
