An automobile diagnostic system monitors in real-time sub-system components. The system has a plurality of acoustic and video sensors in combination for audibly detecting and visually monitoring critical noise levels and/or vibrations in sub-systems such as brakes, shocks, universal joints, exhaust and transmission systems, etc. Each combination sensor is attached a particular sub-system component for monitoring. The data is recorded on a (VCR) system for visual identification and the recording transmitted to a television and Video Cassette. A control panel has a series of Light Emitting Diodes (LEDs) and audible alarms as respective visual and audible alert indicators of tuned frequencies for a particular sub-system component.
