DTC Settings


Reported DTCs

The DTC dialog shows what the ECU reports as error conditions. Use the Clear All button to tell the ECU to clear its current set of error codes.  These may come back, however, if the problem that was causing them to be thrown in the first place has not been resolved.  Use the Update All button to re-read the data displayed in the DTC dialog.

Enabled DTC Checks

Checked boxes indicate which ECU error code check is active.  Uncheck (clear, deselect) the box corresponding to any DTC checks you do not want the ECU to perform.

OBD II Readiness (2G ONLY)

Displays the readiness state of the various OBDII readiness monitors inside the ECU.  Check that these values are listed as COMPLETE and ready before you take your car up to be emissions tested.
