J1587 Packet Detection Problem
Problem: J1587 Packet Detection Fails
Ignition must be ON for the truck to broadcast/supply vehicle data.
Note
: If the
Core Data Items
and
J1939
tests pass (i.e. green check), it’s acceptable for the
J1587 Packet Detection
test to fail. This would mean that the MC P50 system is getting its
vehicle data from the J1939 link. Some 2012 and newer trucks do not submit J1587 packets.
In order to get J1587 data, a truck’s engine must be supplying the J1587 data, a connection
must be made to the J1587 wires (Power/IO cable). Many new trucks/engines do not transmit
J1587 packets.
If packets are not detected, check the connections to the J1587 data link and verify that it is
properly configured.
In 8xx code and higher, the MCP50 will auto detect J1587 bus traffic.
