The Description column of the DTC lists gives a detailed
description of what the DTC means. The descriptions are carefully
written to be unambiguous and to give you a great deal of informa-
tion about the specific fault.
Sometimes the DTC has multiple descriptions, or the descrip-
tion is too lengthy to display on one line. To view the DTC descrip-
tion in a window by itself, double-click the left mouse button on the
row of the description you’d like to view.
Check Engine and Clear
The ability to clear the MIL is as important as it is to view the
DTC that caused it. Clearing the MIL does more than turn off the
indicator light on the vehicle. It also:
• Clears the Stored and Pending DTC codes.
• Clears the Freeze Frame data related to a specific DTC.
• Clears oxygen sensor test data.
• Resets status of system monitoring tests.
• Clears OnBoard monitoring test results.
To clear the MIL and reset all the systems enumerated above,
click the Clear button and select Yes.
Warning: Never clear DTCs without first
determining if repairs are required. Ignoring
necessary repairs could be costly and/or
dangerous.
