WARNING
Use of the ScanGauge while driving could lead to an accident and serious injuries.
The primary attention of the driver should always be on safe driving. As with any
gauge or other instrumentation system in a motor vehicle, the information should
be observed as part of a normal sequence of observations performed in the
operation of the vehicle. Changes to the selections in the ScanGauge should
only be made when it is safe to do so. The driver must remain attentive to driving
the vehicle.
The mounting of the ScanGauge and the routing of the cable connecting it to
the vehicle should be done with suitable caution so it does not create an unsafe
condition. This includes but is not limited to the following restrictions:
• Do Not mount the ScanGauge where it can obstruct the
view of the driver.
• Do Not mount the ScanGauge in a manner that could cause
it to be propelled through the vehicle during an accident
causing injury, such as over or near an air bag.
• Do Not route the cable in a manner that would interfere
with the operation of the vehicle controls.

Installing the ScanGauge
The ScanGauge is simple to install and requires no additional power
source other than the OBD II connector.
There are, however, some important considerations when choosing
a location for your ScanGauge. Please see the Installation section
for detailed information.

ScanGauge Overview
Overview 5
Basic Operation and Features
Menu and Selection Buttons
The ScanGauge 3 has a capacitive touch display. At the bottom of every screen is a small icon, pressing
this button will bring you back to the home screen at any time. There are tabs at the top of many pages
that help to navigate different menu and gauge screens.
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.
User Customizable Gauges
Up to 50 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.

Flash Memory
The ScanGauge uses a type of memory that doesn’t require batteries or a source of power to maintain
settings. 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 tapping the
ScanGauge twice will automatically wake the ScanGauge, and it will return to the gauge screen and
display 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 trip information to be saved in Flash memory and re-
stored when it is reconnected.
Customizable Color Display
Choose from 16 preset colors or program your own for millions of possible colors. The backlight intensity
is also adjustable by swiping up or down with 2 fingers from any screen.
SCAN
Use the Scan Tool feature to view and clear trouble
codes and turn off the check engine light.
GAUGE
Use GAUGE to display up to 9 real-time
Digital Gauges
TRIP
Press the trip button to access the built-in Trip comput-
ers. The built-in Trip computers give you the ability to
view and track useful information about the trip you take
as you drive.
MORE
Press the MORE button to access the
settings and configuration options for the
ScanGauge.
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 Deluxe Window Mount supplied with the
ScanGauge to attach it to the location you have chosen. The
magnetic 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 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:
Connecting Screen Home Screen
Up to 60
seconds
If it does not stop saying “Connecting...” or the screen goes blank after 60
seconds, refer to Troubleshooting on page 34.
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 tapped twice. When communication
has been established, the display will change back to the gauge screen you were on, or to the
Home Screen if it was on another page.
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 12.
Overview 9
Important Installation Considerations
The ScanGauge has an operating temperature range of 0˚F to 160˚F (-18˚C to 71˚C). At higher tem-
peratures, the display will become dark and difficult to read. At lower temperatures, the contrast will be
reduced. As long as the temperature doesn’t exceed –22˚F to 176˚F (-30˚C to 80˚C), the display will
return to normal operation when the ScanGauge temperature returns to the normal operating tempera-
ture range.
• A location in direct sunlight on the dashboard in a closed vehicle could exceed the normal operat-
ing temperature. The use of windshield shades or covering the ScanGauge with something can
significantly reduce this temperature. If attached with Deluxe Window Mount, 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 deploy-
ing 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.
