 Diagnostic Trouble Code Library
Look-up library of DTC definitions
Diagnostic Functions and Data - EEC-V
 DTCs and several diagnostic
tests are available from this
menu
 KOEO and KOER
self-tests are selected
on EEC-V using the scan tool
 Current status of all monitor
Readiness Tests is selected by scrolling
up and down the menu list until the item is
highlighted and hitting Trigger
(More on this later)
Receive/Clear Continuous Codes - EEC-V
 The scan tool will
display any
Continuous Codes
stored in memory
 Use the Rotary dial
to select the DTC you want
information about and hit
the Trigger bar
Code
Description
 The code description
for the highlighted DTC
will be shown in the lower box of the display window
Preparing Vehicle for KOEO and KOER
On Demand
Self Tests EEC-V
This screen prompts
you to prepare the
vehicle for either
KOEO or KOER
On Demand Self-Tests
by bringing the engine
to normal operating
temperature
Displaying DTCs from On Demand
Self-Test EEC-V
If any DTCs
are stored
during the
On Demand

they will be shown
in the display window
Options:
START - Repeats
code retrieval
PRINT - Prints DTCs
STORE - Places all DTCs in the NGS memory
C-ALL - Clears all codes
C-ONE - Clears the highlighted code
System Readiness - EEC-V
If you select
On Board System
Readiness Tests
A display will
appear to inform
you of the system’s
current
Readiness Status
More test information available from the
System
Readiness
Display
TESTS - Displays
current status of
all monitors
MIL - Displays a window telling you which module
triggered the DTC and turned on the MIL
CONT - Sends you to the Generic OBD II functions list
Readiness Status Display
The Readiness
Status Display
gives you the

run to completion
Using Active Command Modes - EEC-V
Select
ACTIVE
COMMAND
MODES with the
Rotary Dial and
hit Trigger
QUESTION: What does Active Command Modes do?
ANSWER: It allows you to activate components.
A separate set of commands in this menu also lets you

Output Test Mode - EEC-V
OUTPUT
TEST
MODE
is available from the
ACTIVE MODES
menu
When you select OUTPUT
TEST MODE, the PCM starts
to activate all actuators it can
control by alternately turning
them ON and OFF
Output Test Mode with PID Monitor
If you hit START,
the PCM will begin
to operate actuators
To view an actuator’s
response, you must first
select it from the list
of all devices by marking
its PID
Select PIDs
In this slide, NO devices have been selected for
monitoring. No PID data will be displayed until
a PID (or PIDs) is selected
Identifying and Selecting PIDs to View
To select a PID
for viewing
in Output
Test Mode:
 Scroll to the

 DIAGNOSTIC MONITORING RESULTS lists all test data
from the last oxygen sensor tests
 PENDING TROUBLE CODES lists any maturing codes
that may store a DTC and turn on the MIL if they are
detected again on the next trip
 ON BOARD SYSTEM READINESS TEST RESULT
lists the pass/fail status of the monitors the last time they ran
 EXPANDED DIAGNOSTIC PROTOCOL
allows you to manually enter or retrieve and existing
numeric string
Readiness Tests - OBD II Interface
TESTS lists
all system

 BLOCK - Selects
a Block of PIDs. Highlight one
PID. Hit the BLOCK key.
Rotate the scroll dial until all
the PIDs in a series are highlighted
DEFN
Button
The DEFN is very
useful since
there are so many
PIDs to identify.
The definition of the
highlighted PID is displayed
at the bottom of the screen
so you don’t have to look
up each definition separately
in a reference manual
