Abstract
A vehicle has a memory which stores operational data regarding the vehicle'"'"'s performance. When the vehicle malfunctions the operational data can be transmitted from a control circuit in the vehicle by a radio frequency signal using the Digital Enhanced Cordless Telecommunications protocol. That radio frequency signal is received at a telephone and the operational recovered. The telephone transfers the operational data via a telephone network to diagnostic computer system which analyzes the operational data to diagnose the cause of the malfunction. The results of the diagnose can be transmitted back to the vehicle.
