Only way to get the cable is through a Linde dealer, if you have pathfinder you must be a linde dealer? I ran the number on TVH with no luck, there is no other way to get the fault code that I'm aware of, if a regulator and carb don't work the next stop would be control valve, assuming you've checked the basics, spark, compression ect..
