What is a Diagnostic Trouble Code (DTC)?
When the OBD system determines that a problem exists, a corresponding trouble
code is stored in the computer's memory and triggers the MIL. These codes help to
identify the problem with the vehicle.
1. The Information Summary screen (Fig.7) tells
you if the check engine light is on, the
number of DTCs and how many
readiness tests are completed.
2. Arrow to the right to view the DTCs (Fig.10).

Manufacturer Specific Codes

NOTE: The list of vehicle types in the vehicle menu is dynamic, based on the text
available for the codes seen on the vehicle.
If the DTC says "The vehicle type is required to display the code description. ENTER
selects vehicle", there is a manufacturer specific DTC present and some configuration
is necessary.
1. Press ENTER to continue.
2. Arrow down through the list and select the
appropriate vehicle type. Selecting a vehicle
type that does not match the connected vehicle
results in the tool displaying incorrect text. If
the connected vehicle name is not listed, select
NOT IN LIST (Fig.11).
3. Continue viewing codes by pressing the right
or left arrows.

Readiness monitors are indicators used to find out if emissions components have
been evaluated. In other words, if all monitors are set to ready, the emissions
components have been tested. In some cases, complex driving patterns need to be
followed to complete these monitors.

NOTE: Clearing the DTCs will remove any DTCs from the vehicle computer and reset
readiness monitors. You can use this feature to make sure vehicle repairs were done
correctly by doing a new read after clearing the codes.
WARNING: Once you reset the readiness test monitors, it may take several days of
driving for those to complete again.
