The Ehubo displays the system checks on engine speed and
hours, as well as vehicle speed, distance, and VIN. This means that
it has retrieved all required data from the ECM.

This example uses the J1939 protocol, which displays for new
trucks. Vehicles using the older communication standard J1708
would also display data on this screen.

6. Tap the Continue button.

NOTE: Contact EROAD at [email protected] if you see a red

X rather than green check marks or if the screen displays the

"Something is not quite right" message.

7. Physically turn OFF the truck. Notice the key icon has turned

red, which is located on the upper right corner of the Ehubo.

8. Tap the Engine O button.

9. The Ehubo is now testing the external power source to ensure

8. OBD-II Installation

Using the OBD-II Bluetooth® connection allows light vehicles to use
ELD technology. A dongle provides the connection to the ECM and
plugs into the OBD-II port. Ground, permanent power, and ignition
are accomplished using the three-wire installation procedure.

Use these instructions if you are installing the Ehubo into a lighter
class vehicle (class 1-6) with an OBD-II diagnostic connector.
Review the instructions and diagrams carefully before you begin.

NOTES

• The engine must be turned o prior to installing the Ehubo.

• Power supply must not be taken from any anti-lock braking
system/electronic braking system (ABS/EBS).

8.1 HARDWARE

1

Connect the 10-way connector (Q) on extendable cable (N) to

the corresponding connector on the Ehubo wiring harness (E).
Secure with cable clamp (J) included in your cable kit.

2

Connect the black wire on the Ehubo wiring harness (E) to an

appropriate grounding location that is fit for that purpose.

3

Connect the red wire on the wiring harness to the inline 2A fuse

(D) (included), and then to a permanent power source.

27

NOTE: Ensure there is a constant 12-24V when the key is
inserted, with the engine running, and also when the key is not
inserted and the engine is o.

4

Connect the yellow wire to an inline fuse (D), then to the

engine or ignition switched power source. Do not connect to an
accessory wire.

NOTE: It is strongly recommended to connect to a source with a
constant 12-24V when the engine is running, and zero volts when
it is not for accurate idle reporting.

You may connect to an ignition source with a constant 12-24V
when the key is in the ON position, and zero volts when the key is
in the accessory (ACC) and OFF positions, if this is not possible.

5

(Optional) If additional wires (orange, brown and gray) (R) from

the wiring harness are required for monitoring activity on the
three digital inputs, connect to their respective sources with an
inline 3A fuse.

6

Insert the EROAD OBD-II wireless adapter into the OBD-II port

of the vehicle ensuring that it is fully seated in position.

7

Finalize by following the on-screen instructions. (See section

8.2) After the checks are successfully completed, the Pending
Assignment, or the Ehubo home screen (if unit is assigned to a
vehicle) is displayed.

8

Store all unused wires neatly, insulated, and secured using cable

ties. Reinstall any dashboard pieces or panels removed during
installation. Remove the screen protection film from the Ehubo
display screen. Ensure the driver-required manual and visor
cards are in the vehicle.

28

NOTE: Electronic logs are activated in Depot after installation.
Contact your Customer Success Account Manager for more
information, if needed.

The Ehubo needs a
permanent power source
and a good view of the
sky to operate optimally.

The curly cable must
remain above the dash.
