Welcome To TD!!!
I have never used an Actron scanner, however...
I was a Commercial Manager at AZ for 6 years after I retired from wrenching and they sold Actron products which I am sorry to say are not very good or reliable.
I have used an OTC Monitor 2000/4000, Snap On MT2500 and Chrysler DRB 2 on FWD Fuel Injected Chrysler vehicles from 84-94.
There is nothing special about a 94 Lebaron, it came with a 3.0L V-6 which was the same engine used previously in the Acclaim/Spirit, Daytona, LeBaron Coupe/Convertible, Shadow/Sundance.
84-94 Chrysler built FWD Fuel Injected vehicles all use the same style diagnostic connector.
(This does not include Mitsubishi built vehicles and Eagle, not sure about the early LH body cars)
You are basically stuck with two options...
1)Try another known good scanner (Other than a Actron) on your vehicle to see if it will communicate properly.
2)Try your Actron scanner on another 84-94 Chrysler FWD vehicle and see if it will communicate properly.
