System tests, using the scan tool
, allow for the display of values as actually seen or commanded
by the following systems:
The test types available are dependent upon the system selected, but
may include the following types:
| • | Data (analog inputs) -- displays analog values as seen by
the system |
| • | Inputs and outputs -- perform the following functions: |
| - | Display digital values as seen by the system |
| - | Provide an indication of whether the input or output has cycled |
| • | Special functions (output controls) -- allow for the outputs
of the system to be set at a desired value (ON or OFF) |
| • | Clear codes -- erases all DTCs stored for the system currently
selected. If the malfunction is still present, the DTC may immediately reset |
