2.4 Verification
Please follow these steps to verify the installation:
1.
Before securing the OBDII converter under the dash, ensure
the LEDs are visible to support a quick operational test.
2.
With everything connected properly, turn the ignition to the
ON position, and start the engine.
3.
Watch the LEDs on the OBDII converter. You should see the
OBDII converter in “detecting vehicle” mode and then
transition to “normal operation” mode. LED definitions are
shown in section 2.5 for reference.
4.
Once the OBDII converter enters normal operating mode,
it should begin to transmit data via the J1708 link to the
TND
™
760 (this may take several seconds).
5.
You will need to login to the TND
™
760. From the 760 main
menu, click on
SYSINFO, DIAGNOSTICS
, and then
JBUS
to
verify the 760 is receiving JBus data. It is normal to see a
message that says “
MISSING PARAMETERS
” since not all
vehicles support all the necessary parameters. Also, the
OBDII converter computes some messages, and those
messages may take additional time to initialize before they
can be sent.
2.3 OBDII Converter Installation Process
1.
Unmount the vehicle OBDII connector.
2.
Mount the OBDII connector on the OBDII Y cable where the
vehicle OBDII connecter was located.
3.
Plug the OBDII Y cable to the OBDII converter, and secure it
by tightening the two screws on the cable.
4.
Connect the OBDII plug on the OBDII Y cable to the vehicle
OBDII port.
5.
Connect the TND
™
760 flying lead cable to the OBDII
converter, and secure it by tightening the two screws on
the cable.
6.
Connect the TND
™
760 cable to the TND
™
760.
7.
At this point the installer should perform the verification
test identified in section 2.4.
NOTE: If there are any issues
with the connections, it will be easiest to trouble shoot
before securing the OBDII converter and the cables.
8.
Mount the OBDII converter in a secure location.
9.
Secure all loose cables, with the zip ties or double-sided tape
provided in your converter kit.
