Int-sl+ worked fine for a bit then quit working

Question

Everything worked fine for a bit but then my instrument cluster quit and displayed a "no bus" message.  Tried to reprogram Int-sl+ but it wom"t program.  Led stays lit all of the time.

Answer 1

The LED is on because something is telling the INT-SL to turn on, this can be from either datalink or the (-)ground-while-running connection causing this. If using datalink remove the white and blue from the datalink connector and reprogram the unit without doing step 5 of the programming.
