Abstract

To permit physical separation and movement between an automotive vehicle and a test or diagnostic apparatus, the transducers transmitting signals representative of vehicle operating characteristics are coupled to a wireless transmitter, for example operating in long-wave, ultra-short-wave, infrared or ultrasonic mode; the signals are received in a wireless receiver constructed to receive the respectively transmitted signals, for application to a test or diagnostic apparatus. The system permits relative movement between the vehicle and the normally stationary diagnostic or test apparatus, for example to carry out diagnosis during movement of the vehicle.
