The following is a brief description of each of the sub
menus in DTC Info and DTC. The order in which they
appear here is alphabetical and not necessarily the way
they will appear on the Tech 2.
DTC Information Mode
Use the DTC info mode to search for a specific type of
stored DTC information. There are six choices. The
service manual may instruct the technician to test for
DTCs in a certain manner. Always follow published
service procedures.
060RW221
DTC Status
This selection will display any DTCs that have not run
during the current ignition cycle or have reported a test
failure during this ignition up to a maximum of 33 DTCs.
DTC tests which run and pass will cause that DTC
number to be removed from Tech 2 screen.
Fail This Ignition
This selection will display all DTCs that have failed during
the present ignition cycle.
History
This selection will display only DTCs that are stored in the
PCM’s history memory. It will display all type A and B
DTCs that have requested the MIL and have failed within
the last 40 warm-up cycles. In addition, it will display all
type C and type D DTCs that have failed within the last 40
warm-up cycles.
Last Test Failed
This selection will display only DTCs that have failed the
last time the test ran. The last test may have run during a
previous ignition cycle if a type A or type B DTC is
displayed. For type C and type D DTCs, the last failure
must have occurred during the current ignition cycle to
appear as Last Test Fail.
MILSVC or Message Request
This selection will display only DTCs that are requesting
the MIL. Type C and type D DTCs cannot be displayed
using this option. This selection will report type B DTCs
only after the MIL has been requested.
Not Run Since Code Cleared
This option will display up to 33 DTCs that have not run
since the DTCs were last cleared. Since any displayed
DTCs have not run, their condition (passing or failing) is
unknown.
Test Failed Since Code Cleared
This selection will display all active and history DTCs that
have reported a test failure since the last time DTCs were
cleared. DTCs that last failed more than 40 warm-up
cycles before this option is selected will not be displayed.
Miscellaneous Test
This test consists of eight menus-Lights, Relays, EVAP,
IAC System, Fuel System, EGR Control, Variable Intake
Manifold Solenoid, and Injector Balance Tests.
In these tests, Tech 2 sends operating signals to the
systems to confirm their operations thereby to judge the
normality of electric circuit.
To judge intermittent trouble,
1. Confirm DTC freeze frame data, and match the
freeze frame data as test conditions with the data list
displayed by Miscellaneous Test.
2. Confirm DTC setting conditions, and match the
setting conditions as test conditions with the data list
displayed by Miscellaneous Test.
3. Refer to the latest Service Bulletin.
Check to see if the Latest software is released or not.
And then Down Load the LATEST PROGRAMMED
SOFTWARE to the replacement PCM.
