5.3 Connecting to a V ehicle
Make a selection from the systems available for testing list a nd instructions for co nnectin g the
Scanner to the vehicle with the data cable display on the scree n (Figure 5-9).
If an adapter and key are needed, the instructions tell you which one s to use, and also where to
locate the vehicle diagnostic connector to perfor m th e selected tests. Refer to the appropriate
Vehicle Communication Software Manual for additional details.
5.3.1 Cables
One of two data cables, one for OBD-II/EOBD compliant vehicles and one for no n-OBD-II/EOBD
models, are used to connect the SCAN MODULE to the test vehicle. The 26-pin end of either
cable attaches to the data cab le por t on t he SCAN MODULE and is secured with two cap tive
screws. The 16-pin end of the OBD-II cable directly plugs into the dat a link connector (DLC) of the
test vehicle. The 15-pin end of the non-OBD-II cable a tt ach es to a cab le adap ter a nd is secured
with captive screws, the adapter then plugs into the diagnostic connector on the te st vehicle .
On-screen instructions on the display device screen tell you which cable, and adapter if needed,
to use once a test vehicle has been identified. The screen message also includ es the loca tion of
the vehicle diagnostic connector that the cable attaches to fo r testing the selected system.
A replaceable 7.5 amp blade-type fuse is inst alled in the vehicle conne ctor end of the cable to
protect the unit from high circuit voltage and current. A green LED, also on the vehicle connector
end of the cable, illuminates whenever there is power supplied to the cable. An LED that fails to
illuminate indicates either a problem on the vehicle power circuit or a blown data cable fuse.
Figure 5-9 Sample vehicle connection message
All OBD-II/EOBD vehicles have vehicle battery power (B+) available on the DLC, so th e SCAN
MODULE should power on as soon as the cable is connected to the vehicle. The auxiliary power
cable supplies power for testing models that do not have B+ available on the diagnostic connector .
An OBD-I Data Cable and adapters (optional in some markets) are required for testing models that
are not OBD-II or EOBD compliant.
27
Page 37
Scanner Operations Navigation
The large end of the auxiliary power cable plugs into the vehicle accessory port. The small end of
the cable fits into a power port built into the side of the cable adapter. An in-line fuse on the
auxiliary cable provides circuit protection.
z To connect the data cable to the vehicle:
1. Follow the on-screen instructions for connecting to the vehicle (Figure 5-9).
2. Once connected, select Continue.
The Scanner establishes communication then displays a list of available tests. If the Scanner
is unable to establish a communications link, a “no communications” message displays.
3. Select from the available tests to open a submenu of te st options.
5.3.2 No Communication Message
When the screen displays a “no communication” message, it means the VERDICT unit and th e
vehicle control module cannot communicate with each othe r for some r eason.
The following conditions cause a “no communication” message to disp lay:
• The Scanner is unable to establish a communication link with the veh icle.
• You selected a system for testing that the vehicle is not equipped with (such as ABS).
• There is a loose connection.
• There is a blown vehicle fuse.
• There is a wiring fault on the vehicle, or in the data cable or ada pter.
• There is a circuit fault in the data cable, Persona lity Key, or adapter.
• Incorrect vehicle identification was entered.

The internal programming of the SCAN MODULE, known as the firmware, can be upda ted using
the VERDICT D7 Display Device. Firmware updates increase the Scanner diagnostic capabilities,
typically by adding new tests, new models, or enhanced application s to th e dat ab ases.
The display device automatically searches for available updates for all of the VERDICT
components when it is connected to the internet. Any updates that are found are downloaded and
stored on the device. However , the update must be inst alled in order to complete the process. This
section describes installing an update to the SCAN MODULE firmware.
When the display device has downloaded and stored a Scanner firmware upd ate it displays a
notification message when Scanner is selected from the VERDICT Home screen (Figure 5-28).
Selecting OK from the firmware update message begins the process as explained in the follo wing
procedure, selecting Cancel closes the message and launches the Scanner. Not updating the
firmware does not impact Scanner operations, the Sca nner remains fully functional but m ay not

Chapter 6 OBD Direct Operations
This Home screen option allows you to access Generic OBD-II/EOBD Scanner tests without
completing a vehicle identification. This option presents a quick way to check for diagnostic
trouble codes (DTCs), isolate the cause of an illuminated malfunction indicator lamp (MIL), check
monitor status prior to emissions certification testing, verify repairs, and perform a number of other
services that are emissions-related. OBD Direct is also used for testing OBD-II/EOBD compliant
vehicles that are not included in the Scanner dat abase s.
OBD Direct is a Scanner function, and the SCAN MODULE must be connected to the test vehicle
and communicating with the display device. Keep in mind, this function on ly provides ge neric
OBD-II/EOBD information. T o acce ss enhanced OBD-II/EOBD functions, select Scanner from the
VERDICT Home screen.
Selecting OBD Direct on the VERDICT Home screen opens a menu with two options (Figure 6-1):
Figure 6-1

6.1.1 Global OBD II Code Check
This option displays any stored emission related generic DTCs reported by the ECM. Selectin g
this option opens a submenu with two choices: Codes and Pending Code s.
Select an option to display the code list. Refer to "Codes Menu‚" on page 37 and the Global OBD
Vehicle Communication Software Manual for additional information.
Codes
The Codes option displays a list of current emission related DTCs.
OBD-II/EOBD Codes have a priority according to their emission severity , with higher priority codes
overwriting lower priority codes. The priority of the code determines the illumination of the MIL and
the code erase procedure. Vehicle manufacturers have implemented the ranking dif ferently, so
there will be differences between makes.
Pending Codes
The purpose of this service is to enable the scan tool to obt ain “pen ding” o r maturing d iagnostic
trouble codes. These are codes whose setting conditions were met during the last drive cycle, bu t
need to be met on two or more consecutive drive cycles before the DTC a ctually se t s.
The intended use of this service is to assist the service techn ician af te r a vehicle r ep air and af ter
clearing diagnostic information, by reporting test results after a sing le driving cycle.
• If a test failed during the driving cycle, the DTC associated with that test is reported. If the
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically
cleared from memory.
51
Page 61
OBD Direct Operations OBD Health Check
• T est results repo rted by this service do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, then a DTC is set to indicate a
faulty component or system, and the MIL is illuminated.
6.1.2 Global OBD II Clear Codes
This option is used to clear all emission related diagnostic data such as, DTCs, freeze frame data,
and test results from the memory of the selected ECM. Although OBD Direct only displays generic
OBD-II data, clearing codes erases all of the stored data including any enhanced codes.
A confirmation screen displays when the clear codes option is selected to prevent accidental loss
of data. Select Yes on the confirmation screen to co nti nue. Refe r to "Cod es Menu‚" on page 37

certain attributes of the test vehicle must be entered into the VERDICT unit so that the correct data
can be retrieved. Vehicle identification information is carried over if you enter the Component T est
module either from the SCAN MODULE or from one of the records stored in th e Vehicle History
module. However , you may need to ente r additional a ttributes in some in st ances.
The vehicle identification sequence is menu driven, you simply follo w the scree n prompts and
make a series of choices. Each selection you make advances you to the next screen.
7.1.1 Creating a Favorites List
Once a Component Test database is loaded, a list of manufacturers displays. This list is often long
and includes makes that are not frequently used. A toolbar a t the top of the scr een allows you to
custom configure the manufacturer list to display only the makes you frequently service.

"Sample active menu select mode screen‚" on page 71.
The displayed values continue to update until the Min/Max key is pressed again, then:
• A short press of the Min/Max key resets the readings
• A long press of the Min/Max key returns to normal V olts DC mode.
S Key, Special Functions
The S key is used to activate special time measurement functions available when sampling
voltage. Each press of the S key advances to the next function in the following order:
1. The screen changes to show the frequency, period, and duty cycle of the test sig nal.
2. The screen changes to show the frequency, period, and pulse wid th o f the test sign al.
When displaying frequency, the period (abbreviated PRD on the screen) represen t s the
percentage of the duty cycle, or the “on time” of the signal. Readings are displayed in milliseconds.
The Freeze (F2) and Range (F3) sof t keys remain active in this mo de. Figure 8-5 shows a typical
frequency display following a single press of the S Key. Press the S Key a second time and the
duty cycle (DTY) reading changes to show the pulse-width (PWD) of the signal in milliseconds.
i Press and hold the S key at any time to instantly return the display to a voltage readi ng.
In this special time measurement mode, the readings shown on the scre en are integr ated, or
filtered. This means that the displayed values show average time-based measurements with great
accuracy, but do not capture fast signal anomalies such as instant aneous “g litches” o r timing
shifts. However, these types of fast signal changes can be seen using the Graph key.

M2 Data Acquisition Device Digital Multimeter Operations
Graphing Voltage Measurement Screens
The VERDICT M2 can generate a graphical history of a voltage sign al over time, which is called a
histogram. Pressing the Graph button when oper ating in Volts DC or Volts AC range causes the
display to change from a digital reading to a graphical disp lay.
While viewing a histogram, the function keys operate as follows:
• F1—switches peak detection on and off
• F2—freezes and unfreezes the histogram (pauses and re sumes data collection).
• F3—incrementally increases the me asureme nt range . The Range key increment ally
decreases the measurement range.
• F4—incrementally increases the timescale of th e histogram. T he Graph key incrementally
decreases the timescale.
A digital value of the signal displays in the upper-right corner of the display wh ile operating in
graphing mode.
Graphing with Min/Max Function
In the Volt s DC graphing function you can capture and store the minimum and maximum voltages
by pressing the Min/Max soft key. The readings appear in the upper-left portion of the LCD. The
VERDICT M2 device captures and reports very fast events (as fast as 50 microseconds) in this
mode, which is only available in Volt s DC.
Press the Min/Max key and the display shows both the instan t aneou s volt age reading ( large
characters) and the minimum and maximum volt ages that occurred since the last time the key was
pressed. The displayed values continue to update until the “Min/Max” key is pressed again. Then
the values reset the readings on the display begin the process again. Press and hold the Min/Max
key to cancel this function, and return to the normal volts DC mode.
z To exit graph mode:
• Press and hold the Graph key for two se cond s.
Graphing Time-Based Measurement Screens
z To access time-based measurement graphs:
1. Press the Graph key.
2. Press the S key.
The VERDICT M2 is now in time-based measurement mode.
In this mode, the VERDICT M2 uses a specialized strategy called “cycle-by-cycle” (C-B-C)
time-based measurements to capture signal glitches. To do this, the VERDICT M2 unit examines
each cycle of the signal under test, calculates its period, duty cycle and pulse width, and generates
a graphical history of that signal (called a histogram). Any significant variation of the signal is
visible on the histogram.
When you initially enter this mode, the system shows frequency histograms (the default setting).
A press of the S key switches the display from frequency to duty cycle. A second press of the
S key switches the display from duty cycle for pulse width.
There three items displayed on the LCD in the graph mode:
73

M2 Data Acquisition Device Digital Multimeter Operations
• A histogram of the signal being measured displays across the screen
• The averaged result of the timing measurement appe ars on the upper-right side of the screen
• The minimum and maximum value readings display on the upper-left side of the screen (after
first pressing the Min/Max key).
Range
A press of either the Range or F3 key takes the meter ou t of the automatic volt age scale fun ction

NOTE:
With the scope in the trigger mode the soft keys perform the fo llowing functio ns:
• F2 Slope—pressing the F2 key switches triggering back and forth betwe en the rising
(positive) edge and trailing (negative) edge of the waveform. A graphic in the upper-right
corner of the display screen shows the currently selected slope.
• F3 Level—short presses of the F3 key incrementally increase the trigger voltage level. An
indicator to the right of the screen graph shows the current trig ger voltage level. Short presses
of the Range key incrementally decrease th e trigger voltage level. Press and hold either key
(F3 or Range) to return to the default setting.
• F4 Channel—a press of the F4 key switches triggering between chan nel 1 (CH1) and channel
2 (CH2). The channel currently selected for triggering is shown at the top of the screen.
i Triggering is not available when the timebase setting is between 1 seco nd and 10 se conds.
Preset Selections
These options allow you to select from already configured scope setups for commonly tested
items. Six preset configurations are available; three for Preset A and three for Pre set B. These
preset conditions are permanent and cannot be erased or modified. However, you can construct
and store additional presets within the D7 Display Device as explaine d in the Scope and
Multimeter chapter of this manual.

The F2, F3, and F4 fields on the screen are acronyms for the type of test the preset is configured
to perform. Interpret as follows:
• Preset A:
– CGI&S—ground controlled injectors and solenoids
– LF AC—low frequency alternating current s ign als
– HF AC—high frequency alternating current signals

Special Selections
The Special settings allow you to alter the way the trace is d isplayed in order to readily spot signa l
anomalies and to compare signals. A short push of the F2, F3 , or F4 key activa tes the ind icated
special mode, a long push of the key cancels the special mode.
Peak
Pressing the F2 key switches on the peak capture function, which allows you to see very fast
signal transitions or glitches. When peak capture is active, “P1” displays at the top of the screen.

During normal operation, the scope collects just enough da ta sam ples to plot a waveform across
the screen. When peak is active the scope samples data at the maximum highest r ate, which
collects more data than what is nee ded to simply construct a waveform across the screen .
Therefore, any signal glitches or fast events are captur ed.
Invert
Pressing the F3 key inverts, or switches, the polarity of the signal trace so that it appears
upsidedown on the screen. This is typically used to sample ampera ge or hi gh-volt age sign als.
Coupling
Pressing the F4 key switches the input to the meter from DC coupling (default) to AC coupling. In
this mode the average value of the waveform is subtracted so that small signal variations become
apparent. AC coupling blocks the DC portions of an input signal in order to amplify the AC portions
without driving them off of the screen. Use for viewing alternator ripple or fuel pump amperage.
Position Selections
The Position selections allow you to reposition the baselines of the channel 1 and channel 2 tr aces
vertically on the screen.
Figure 8-16 Sample screen with both traces repositioned
Channel 1 Trace
Use the F2 and Min/Max keys to reposition the channel 1 trace as follows:
• Short pushes of the F2 key moves the trace increment ally up.
• A long push of the F2 key places the trace at the midpoint of the scale.
• Short pushes of the Min/Max key moves the trace incrementally down.
• A long push of the Min/Max key places the trace at 10% of the scale.

Channel Selections
The channel selection mode allows you to switch the trace on an d of f. T he F2 key controls th e
channel 1 trace and the F3 key controls the channel 2 trace. Pressing the key the first time turns
this channel “off” and the sweep signal is removed from the display. Pressing the key a second
time puts this channel back onto the display. The previous characteristics for this channel are
saved during this process. The indicator at the base of the screen appears as inverse video (white
lettering on a black background) when a channel is on.
Bluetooth Discovery Selection
A special Bluetooth Discovery mode is available when operating in oscilloscope mode. Bluetooth
Discovery allows the M2 unit to be “paired” and connected to a host computer . This function is only
used when the VERDICT M2 has not been previously paired with a host, or if it becomes
necessary to pair with a new host. The VERDICT M2 can only be p aire d with one ho st at a tim e.
When Bluetooth Discovery is enabled, the VERDICT M2 seeks a compatible host computer, such
as the D7 Display Device. If a compatible device is within range, the VERDICT M2 recognizes its
presence, and can initiate pairing if so instructed by the operator. The pairing function requ ires
active participation of an operator . Once p airing has been established, the ope rator must exit from
the Bluetooth Discovery mode.

Although the discovery mode has been disabled, the two-p aired devices automatically seek and
find each other when they are powered on. The VERDICT M2 becomes “invisible” to other
Bluetooth devices whenever discovery is disabled.
8.2.8 Remote Functions
With the Rotary Switch in the Remote Functions position the VERDICT M2 attempts to
communicate with a host computer. This could be either a display device with which the
VERDICT M2 has been paired, or one that it wants to pair to.
