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...
<TRIP MORE>
Connecting Screen
<SCAN
<TRIP
GAUGE>
MORE>
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 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.
