Scan Tool Display

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:

FAIL THIS IGN.

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

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.

LAST TEST FAIL

Indicates that this DTC failed the last time the test ran. The last test may have run during a previous ignition cycle if an "A" or "B" type DTC is displayed. For type "C" DTCs, the last failure must have occurred during the current ignition cycle to appear as Last Test Fail.

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).

NOT RUN SCC

Not Run Since Code Clear. 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.

TEST FAIL SCC

Test Fail Since Code Clear. Indicates that this DTC that has reported a failure since the last time DTCs were cleared.
