#### Passthrough CAN Mode
-The `passthrough` command controls the passthrough mode for each of the CAN
-buses. There are three passthrough modes:
-
-* `off` - Only the specified simple vehicle messages are processed and output
- from the VI.
-* `filtered` - If the CAN acceptance filter is not otherwise disabled, only the
- pre-defined CAN messages (i.e. those compiled with the firmware) will be
- output in the low-level CAN format from VI.
-* `unfiltered` - All received CAN messages will be passed through from the bus
- to the VI's output.
+The `passthrough` command controls whether low-level CAN messages are passed
+through from the CAN bus through the VI to the output stream. If the CAN
+acceptance filter is in bypass mode and passthrough is enabled, the output
+stream will include all received CAN messages. If the bypass filter is enabled,
+only those CAN messages that have been pre-defined in the firmware are
+forwarded.
