DTC Selections

DTC Status

This selection will display any DTC(s) that have not run during the current ignition cycle or have reported a test failure during this ignition cycle up to a maximum of 40 DTC(s). DTC tests which run and pass will cause that DTC number to be removed from this scan tool display.

Fail This Ign. (Fail This Ignition)

This selection will display all DTC(s) that have failed during the present ignition cycle.

Last Test Fail

This selection will display only DTC(s) that have failed the last time the test ran. The last test may have ran during a previous ignition cycle if an A or B type DTC is displayed. For type C DTC(s), the last failure must have occurred during the current ignition cycle to appear as Last Test Fail.

MIL Request

This selection will display only DTC(s) that are requesting the MIL. Type C DTC(s) cannot be displayed using this option. This selection will report type B DTC(s) only after they have requested the MIL. (failed twice).

Not Run SCC (Not Run Since Code Clear)

This selection will display up to 40 DTC(s) that have not run since DTC(s) were last cleared. Since any displayed DTC(s) have not run, their condition (passing or failing) is unknown.

Test Fail SCC (Test Failed Since Code Clear)

This selection will display all active and history DTC(s) that have reported a failure since the last time DTC(s) were cleared. DTC(s) that last failed over 40 warm-up cycles will not be displayed.

History Code

This selection will display only DTC(s) that are stored to the PCMs history memory. It will not display type B DTC(s) that have not requested the MIL. It will display all type A DTC(s) and type B DTC(s) (which have requested the MIL) that have failed within the last 40 warm-up cycles. In addition, it will display all type C DTC(s) that have failed within the last 40 warm-up cycles.

Capturing DTC Info (Capture Info)

Selecting this option on the scan tool allows the technician to record the Freeze Frame and Failure Records that may be stored in the PCMs memory. This can be useful if the PCM or battery must be disconnected and later review of the stored information may be desired.
