I have the J1708 bus and am connected ok to adapter and dash works but I have a constant fault of ABS
with a light on my MH dash.
Fault ID 84 FM 2 CNT 0 (Wheel Based Vehicle Speed Data)
The fault shows up on my old ScanGauge unit
I can clear it there and it will come right back in the ScanGauge
and I can get the BlueFire to see the fault and send it to my email
but it does not show up on the Faults Page in the dash.
When not connected to the adapter it will show sample faults on the Faults Page
and sent the demo faults to my email.
