Scan Tool Display

WARNING: This page is about a different car, the 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: OBD-II vehicles have options available in the scan tool DTC mode to display enhanced information available. However, to fully utilize information and procedures requires the use of a Tech 2 scan tool. See scan tool operator's manual for additional information.

The following are Tech 2 scan tool sub-menus in the DTC INFO and SPECIFIC DTC modes:

  1. DTC INFO MODE

    Used to search for specific type of stored DTC information. There are 7 choices in this mode. Technician may be instructed to test DTCs in a certain manner. Follow the affected DTC test procedures. To get complete description of any status, hit ENTER key before pressing the desired "F" key.

  2. DTC STATUS

    When the scan tool displays a DTC, the status of the DTC is also displayed. The following DTC statuses are indicated only when they apply to the DTC that is set.

  3. FAIL THIS IGN.

    This selection will display all DTCs that have failed during the present ignition cycle.

  4. HISTORY

    Indicates that the DTC is stored in the PCM History memory. Type "B" DTCs will not appear in History until they have requested the MIL (failed twice). History will be displayed for all type "A" DTCs and type "B" DTCs (which have requested the MIL) that have failed within the last 40 warm-up cycles. Type "C" DTCs that have failed within the last 40 warm-up cycles will also appear in History.

  5. LAST TEST FAIL

    This selection will only display DTCs that have failed the last time the test ran. If type "A" or "B" DTCs are displayed, the last test may have ran during the previous ignition cycle. For type "C" DTCs, the last failure must have occurred during the current ignition cycle to be displayed as LAST TEST FAIL.

  6. MIL REQUEST

    Indicates that this DTC is currently requesting the MIL. This selection will report type "B" DTCs only when they have requested the MIL (failed twice).

  7. NOT RUN SCC

    DTCs will be listed in this category if the diagnostic has not run since DTCs were last cleared. This status is not included with the DTC display since the DTC can not be set if the diagnostic has not run. This information is displayed when DTC Info is requested using the scan tool.

  8. TEST FAIL SCC

    Indicates that this DTC that has reported a failure since the last time DTCs were cleared.

  9. FAILED SINCE CLEAR

    This message indicates the DTC has failed at least once within the last 40 warm-up cycles since the last time DTCs were cleared.

  10. NOT RUN SINCE CL.

    Not Run Since Cleared message indicates that the selected diagnostic test has not run since the last time DTCs were cleared. Therefore, the diagnostic test status (passed or failed) is unknown. After DTCs are cleared, this message will continue to be displayed until the diagnostic test runs.

  11. NOT RUN THIS IGN.

    Not Run This Ignition message indicates the selected diagnostic test has not run this ignition cycle.

  12. TEST RAN AND PASSED

    This message indicates the selected diagnostic test has:
    • Passed the last test.
    • Ran and passed during this ignition cycle.
    • Ran and passed since DTCs were last cleared.
    • Check has not failed since DTCs were last cleared.

    If this message is displayed, repair is complete. If FAILED THIS IGN. message is displayed, repair is incomplete and further diagnosis is required.
