J1939 CAN BUS CONNECTION
The J1939 CAN (Controller Area Network) Bus is a
communications standard designed to permit vehicle devices
to communicate with each other. To enable the full range
of the Autovue
®
LDW system by Bendix CVS features, the
designated wires in the harness need to be connected to
the J1939 CAN Bus.
NOTE: For vehicles built since 2005, the J1939 CAN Bus
is almost always activated. In rare cases where J1939 CAN
Bus is not found, see the Troubleshooting section.
Most vehicles have a 6- or 9-pin diagnostic connector, near
the driver-side door, typically low down on — or under —
the dash. See Figures 4 and 5. This connector is used by
PC Diagnostics to examine engine performance data and
Diagnostic Trouble Codes (DTCs), and is an ideal point to
connect the AutoVue LDW system harness.
Gain access to the wires behind the connector. A yellow
and green twisted pair of wires is the Standard for J1939
CAN Bus wiring; see the AutoVue LDW system harness
