  • VEHICLE DIAGNOSTIC CODE COMMUNICATION DEVICE AND A METHOD FOR TRANSMITTING DIAGNOSTIC DATA UTILIZING THE VEHICLE DIAGNOSTIC CODE COMMUNICATION DEVICE
    Publication number: 20080201032
    Abstract: A vehicle diagnostic code communication device and a method for transmitting diagnostic data utilizing the vehicle diagnostic code communication device are provided. The vehicle diagnostic code communication device includes a diagnostic link connector configured to receive signals indicating a diagnostic code associated with vehicle operation and a microprocessor operably coupled to the diagnostic link connector. The microprocessor is configured to determine at least one of diagnostic textural data and diagnostic audio data based on the diagnostic code and to induce an RF transmitter to transmit a first RF signal having at least one of the diagnostic textual data and the diagnostic audio data.

  • Enhanced vacuum decay diagnostic and integration with purge function
    Patent number: 6722187
    Abstract: The present invention relates a method of detecting leaks and blockages in a fuel system. The leaks are detected using a RAMPOFF mode and a TANK mode. The RAMPOFF mode modifies the evaporative diagnostic purge logic to increase the ramp down rates of the evaporative purge duty cycle to aggressively shut off the purge solenoid valve for tests used to detect leaks as small as 0.02 inches in diameter. The TANK mode modifies the evaporative diagnostic purge logic to support aggressive purging requirements for tests used to detect larger leaks of greater than 0.04 inches in diameter. The MASS FLOW mode modifies the evaporative diagnostic purge logic to hold a constant purge mass flow rate necessary to detect blockages across a vent solenoid valve. The RAMPOFF mode, TANK mode, and MASS FLOW modes support evaporative diagnostics that are run continuously within a fuel system when acceptable engine operating conditions are present.
