Obd Connector - Vision 1480 Series Owner's Manual

OBD CONNEC TOR
PURPOSE
An OBD2 connector is included with most 1480 systems, and the following
4 wires are already connected to it:
1)
2) (–) Ground Input
3) CAN-H
4) CAN-L
Toyota, Lexus and Nissan cars allow you to merely connect the OBD2 plug
to your car's OBD2 connector, and then you need only connect the BROWN
wire to the Siren (plus any optional connections — see page 13).
Other cars like Honda allow you to connect the OBD2 plug to your car in
CAN wires will need to be cut off from the OBD2 plug and connected manu-
ally using the included PosiTap connectors. In addition, some Honda cars
use a 1-wire CAN system, so CAN-H and CAN-L are not used at all, and the
1480's GREEN wire is used instead.
WARNING!
If you connect the OBD2 connector with all 4 wires attached to HONDA
cars that have 1-wire CAN, you will cause a fault in the car's body
computer. Such will result in a Warning light that can only be reset
at the dealer, at your expense. READ ALL 1480 DOCUMENTATION
BEFORE CONNECTING ANYTHING!
ORIENTING WIRES
The OBD2 connector included with the 1480 has a special feature that al-
lows you to decide from which end the wires exit the connector, as shown in
the diagram atop on the next page. This is useful because the direction you
must insert the OBD plug varies from car to car.
Once you have oriented the wires as you like, simply slide the cap back over
the circuit board and then use a wire tie to secure the wires as shown.
