System Tests Using Scan Tool

System Tests, using the scan tool, allow for the display of values as actually seen or commanded by the various systems (i.e. PCM, IC, SDM, EBCM, or BFC). The Test Types available are dependent upon the System selected, but may include the following:
^ Data (Analog Inputs) - displays analog values as seen by the system.
^ Inputs and Outputs - displays digital values as seen by the system and provides an indication of whether the input or output has cycled.
^ Special Functions (Output Controls) - allows for outputs of the system to be set at a desired value (ON or OFF).
^ Clear Codes - will erase all DTCs stored for the system currently selected (Note: If the malfunction is still present, the DTC may immediately reset).
