Basic Operation and Features
Menu and Selection Buttons
The ScanGauge interface is made up of 5
buttons; one HOME and 4 function/select
buttons. The HOME button, located in the lower
right corner of the front face and marked with a
red circle, has a single function — to display the
Home Screen. Pushing the HOME button will
always display the Home Screen as shown to
the right.
The function/select buttons are located at each corner
of the display. The function of these buttons will vary
depending on the particular screen you are currently
viewing.
In general, when a “<” or “>” is displayed next to the
button, pressing the button will move you to the next or
previous selection for the currently selected feature .
To the left are a few examples of screens you may
encounter while using your ScanGauge. Use the
diagram for an explanation of possible button functions.
Automatic Mode Recognition
Different vehicles use different types of signaling from
their computers. In most cases, the ScanGauge can
quickly determine which type your vehicle is using. You
don’t have to know which type it is for it to be used.
Automatic Repeat Buttons
Pressing the buttons and holding them for more than a
second will cause them to automatically repeat at a rate
of about 2 times a second. This allows for rapid step-
ping to a value without a lot of button pressing.
User Programmable Gauges
Up to 25 trip, vehicle specific or special gauges can be
entered into the ScanGauge. These are stored in Flash
memory and will be retained even if there is a power
loss, but the user can change them as often as desired.

User Programmable Commands
Up to 10 commands can be generated, edited, saved and sent to the vehicle computer. This allows for
future codes and some special commands to be added by the user.
Flash Memory
The ScanGauge uses a type of memory that doesn’t require batteries or a source of power to maintain.
This means that your settings will not be lost if you disconnect the vehicle battery or disconnect the
ScanGauge.
Automatic Sleep Mode
About 12 seconds after turning off the vehicle or pressing a button after the vehicle engine is turned
off, the ScanGauge will automatically power down into a sleep mode. Starting the engine or pressing
the HOME button will automatically reactivate the ScanGauge, and it will return to the screen and lamp
settings it had just before it went to sleep.
If you need to disconnect the ScanGauge, wait until it has gone to sleep before
you do it. This will allow all settings and trip information to be saved in Flash
memory and restored when it is reconnected.
Customizable Backlight Color
Choose from 7 standard backlight colors or program your own for 63 possible colors. The backlight
intensity is also adjustable and can be set to Off, Low and High intensities.

Overview 7

1. Locate the OBDII connector.
This connector is normally located under the dash on either side of
the steering column. It can also be located under the dash on the
passenger side in some vehicles. On rare occasions it is behind the
ashtray in the dash or in the armrest. It may have a cover on it that
can be pulled off by hand.
2. Locate a place for the ScanGauge.
You can use the sticky-back Velcro®supplied with the ScanGauge
to attach it to the location you have chosen. The Velcro®attachment
allows you to easily remove it and use it to troubleshoot another
vehicle and then return it to this vehicle.
The location should be where it can easily be seen from the normal
driving position. It should not be placed where it will obstruct the
driver’s view outside the vehicle or of other gauges.
DO NOT mount the ScanGauge over an air
bag cover where it could be propelled by a
deploying air bag.
3. Route the cable.
Route the cable from the OBDII connector and plug the small end
of the cable into the back or side of the ScanGauge.
IMPORTANT: A pin in the cable is connected
to the vehicle’s 12V system. Do not short any
pins of the small connector to metal or other
ground when the OBDII plug is plugged into
the OBDII connector.
4. Turn the vehicle on.
If the vehicle can be run, start it. If it cannot be run, turn the key
to the Run position. This is the position it is normally in when the
vehicle is being driven.
5. Plug the ScanGauge plug into the OBDII socket.
The ScanGauge derives all the power it needs from the OBDII
connector. No other connections are needed for its operation.
Wait for the ScanGauge to connect. When the ScanGauge is first connected, it attempts to

communicate with the vehicle. Communications can be established with the key in the Run position,
even if the engine is not actually running. It could take up to 60 seconds for the connection to be
made after the unit is plugged in with the key in the Run position.
While establishing communications, the screen will display:

If it does not stop saying “Connecting...” or the screen goes blank after 60
seconds, refer to Troubleshooting on page 52.
The TRIP and MORE buttons can be used even if a connection is not established. If communication
with the vehicle ECU is not completed within about 75 seconds, the ScanGauge goes to sleep. It will
continue to attempt to connect when the vehicle is restarted or the HOME button pressed. When
communication has been established, the display will change over to that which was displayed the
last time it went to sleep or to the Home Screen.
6. If this is the first time it has been used on this vehicle, follow the
procedures outlined in Setting Up Your ScanGauge, on page 11.
•A location in direct sunlight on the dashboard
in a closed vehicle could exceed the normal
operating temperature. The use of windshield
shades or covering the ScanGauge with a
piece of paper can significantly reduce this
temperature. If attached with Velcro®, you can
also move it temporarily to a location away
from the sun.
•DO NOT mount the ScanGauge over an air
bag cover where it could be propelled by a
deploying air bag.
•A pin (pin 16) in the cable is connected to the
vehicle 12V system. DO NOT short any pins of
the small connector to metal or other ground
when the OBDII plug is plugged into the OBDII
connector.
•The location should be where it can easily be
seen from the normal driving position. It should
not be placed where it will obstruct the driver’s
view outside the vehicle or of other gauges.

Currency Type CURRENCY $, £, ¥, € Choose the currency symbol ScanGauge
should use to display monitor values.
Tips for Setting the Tank Size
The size will use Gallons or Liters depending on the selection you made in the Fuel Units Screen (FUEL
UNITS). If the size in the manual is not in whole units, use the next lower value. For instance, if the
capacity is 17.5 gallons, use 17 gallons.
It is dangerous to run a vehicle out of fuel and can damage the fuel pump. Do
not rely on the fuel gauge or ScanGauge at low fuel levels or low remaining
distance or time.
12 — www.ScanGauge.com

Can the ScanGauge use Imperial Gallons?
ScanGauge uses gallons as a unit label, not a unit of measurement. Because of this, it can read in either
US or Imperial Gallons without conversion. Make sure all units entered into ScanGauge are consistent,
and the readings should remain accurate for US or Imperial Gallons.
Can ScanGauge Display Liters per Hundred Kilometers?
By default, ScanGauge will express fuel economy in Liters per Hundred Kilometers (LHK), provided you
have set fuel to LITERS and distance to KILOMETERS. For more information see LHK under Advanced
Setup on page 14.
Diesel Vehicles: Determining the Diesel Type
If your vehicle uses diesel fuel and you’re not sure which setting to use in the FUEL TYPE parameter,
you can determine the type by performing the following procedure:
•Set the ENGINE SIZE to match the liter size of your vehicle’s engine
•Set FUEL TYPE to DIESELa.
•Run the engine until warmed up to operating temperature.
•Park the vehicle and set it in Park or Neutral.
•While the engine is idling, select GAUGE from the Home Screen, and set one of the gauges to show
RPM and another to show GPH. You can set the gauges by pressing the function buttons next to the
gauge position you wish to change.
•Make note of the GPH value.
•Next, use the throttle to raise the engine
RPM to about 1500 RPM. If the GPH reading
increased, you have a DIESELa vehicle. If
the GPH dropped or stayed the same, you
have a DIESELb vehicle and should change
the FUEL TYPE to DIESELb.

UPDATE RATE
You can adjust the rate in which ScanGauge reports
data. The effect of this setting is most visible in the
Gauge Screen.
The update rate defaults to NORMAL. In some cases, a faster update rate can be used. If this causes
some updates to be skipped or irregularly operate, FAST should not be used. In some cases, even
NORMAL can be too fast and lead to poor operation.
In these cases, SLOW should be used. PWM and all the CANxx modes can usually use FAST rate. VPW,
ISO and KWP modes may have a problem with a rate higher than NORMAL.

wear or any other factor that may affect the accuracy of your vehicle’s speedometer. It is important to note
that this adjustment only affects the ScanGauge’s indicated speed and distances, and it does not affect
the vehicle speedometer or odometer readings.
While viewing the SPEED Screen, the lower left and right function buttons can be used to increase or
decrease the selected adjustment in 1% steps.
The upper line displays the word SPEED and a percentage. The percentage is the adjustment factor. The
lower line displays 2 numbers: the left number is the speed reported by the vehicle and the number on the
right is the speed that will be shown by the ScanGauge after applying the correction factor.
One accurate way to set the speed is to use a GPS. With one person driving, the other person observes
the speed on the GPS and adjusts the percentage until the lower right number agrees with the speed the
GPS indicates.
For more information about the various methods of calculating your speed adjustment, visit us online at
www.ScanGauge.com/quick-tips/.
IMPORTANT: OBSERVE ALL SPEED LIMITS AND DRIVE SAFELY WHILE MAKING
THESE ADJUSTMENTS. THE DRIVER MUST NOT BE DISTRACTED BY TRYING TO
MAKE THESE ADJUSTMENTS WHILE DRIVING.
Set the Fuel Cutoff Level
Some vehicles will turn the fuel injectors off while
coasting – this is known as Fuel Cutoff. ScanGauge
attempts to detect the fuel cutoff condition by
comparing the open/closed loop indicator and the
throttle position. If ScanGauge improperly detects fuel cutoff, then you may see fuel economy being
reported as 9999 MPG or 0.00 LHK.
The CUTOFF parameter allows you to set the point at which ScanGauge can determine the throttle is
closed and in the fuel cutoff condition. The default value of 24 is usually correct for most vehicles but may
need to be adjusted. This setting is not critical but is best at about 4 above the no-throttle TPS value. You
can choose to disable the fuel cutoff sensing feature of the ScanGauge by setting the value of CUTOFF
to 0.
Set PID Method
Use the PIDS menus to set the method ScanGauge
uses to store Parameter Identifications Descriptors
(PIDs) codes.
Most vehicles use ALL, which is the factory default. But some vehicles will not work properly unless
SUPPORTED is used. This is the case for 1995 to 1999 Subaru vehicles. If the ScanGauge connects but
then goes to sleep after showing little or no data on the GAUGE display, change this to SUPPORTED.

LHK
Liters per Hundred Kilometers (LHK) is a popular way to
express fuel economy in Europe.
By default, ScanGauge will express fuel economy in
LHK, provided you have set fuel to LITERS and distance
to KILOMETERS as outlined in the Basic Setup procedure (see page 12).
If you would prefer fuel economy to be express as Kilomiter Per Liter (KPL), set the LHK parameter to
OFF. With LHK set to OFF, and fuel and distance set to LITERS and KILOMETERS, the ScanGauge will
now express fuel economy in Kilometers Per Liter (KPL).
IMPORTANT: Lower LHK values represent a higher fuel economy, unlike KPL
where a higher number represents higher fuel economy.
DTC
Some vehicles may not respond properly when
attempting to retrieve or clear Diagnostic Trouble Codes
(DTC). By default, this parameter is set to NORMAL. If
you experience trouble, set this parameter to ALT.
Set the Sleep Event
By default, the ScanGauge will shut down when it sees 0
RPM. This may not be the desired setting if your vehicle
is a Hybrid, which will report 0 RPM when the vehicle
is stopped. When you select HYBRID in the fuel type
(TYPE) parameter in the Basic Setup procedure (see page 11), ScanGauge will automatically set the
Sleep Event parameter to NO COM.
When using ScanGauge with the Sleep Event parameter set to NO COM, there is a small risk that the
vehicle’s ECU and ScanGauge will stay on and drain the battery. You must be sure the ScanGauge goes
to sleep properly when the engine is turned off.
Set a Horsepower Adjustment
ScanGauge reports Horsepower (HP) as a built-in digital
gauge. This parameter allows you to make adjustments
to the HP reading ScanGauge reports.
Set the Manifold Pressure Method
If your vehicle is equipped with a turbocharger or
supercharger, you may want your vehicle’s manifold
pressure calculated and reported as Boost (BST)
as opposed to Manifold Absolute Pressure (MAP). This parameter allows you choose the method
ScanGauge should use to calculate and display manifold pressure.

Calibrating Your ScanGauge
Improving the Accuracy of Your ScanGauge
The accuracy of your ScanGauge can be improved by calibrating the fuel consumption. Calibrating
your ScanGauge to accurately report fuel consumption is a 2-step process: your first fill-up and your
second fill-up.
While both steps involve using the FILLUP function of your ScanGauge, the procedures for Step 1 and
Step 2, vary slightly from each other. Please read carefully.
Access the FILLUP Menu
To access the FILLUP screen, press the function button next to MORE on the Home Screen. The next
screen will be the FILLUP screen. Press the upper right function button to enter the Fill-up function.
Before proceeding, read through the tips below for some helpful information and the procedure for your
first fill-up.
Follow these calibration instructions only when
you are filling your fuel tank. If you do not fill your
tank to its capacity, then the calibration process will
not produce accurate results.
1) Fill up the tank, letting the pump shut off automatically.
2) Use the FILLUP function to tell ScanGauge you have
filled the tank. From the Home Screen, follow the
sequence shown to the right.
3) On your first fill-up, DO NOT make any
adjustments to the indicated fuel. Simply press the
lower right button to move to the next screen.
