Customer Question

Trying to use dr zx to check a engine alarm warning code. I bought a palm pilot version and it has a six pin plug with three pins in it. Should it have all six for my zx270 LC-3? When I plug it in it says communication error check serial cable or harness between dr zx and icf.
JA: What is the complete model and serial number of your machine?
Customer: ZX 270 LC-3 ff01v440030316
JA: Anything else you want the construction mechanic to know before I connect you?
Customer: Yes. I had a mechanic put a new head and head gasket on machine. It fires with starting fluid but is not getting fuel. We checked everything to the injector pump.. All checks out. I feel if I could read the code its throwing I could avoid replacing parts that don't need replaced.

These cables aren't right. I have a six pin dr zx plug in my machine. I don't have a part number for the cable I have as I bought it as a package from simco. It fits the plug in my machine but has three pins.

It will not need all pins to read the data. Click on this link

those are the two cables shown in the diagram I posted.

Customer: replied 1 month ago.
My zx270 LC-3. Has two black fuse boxes and one six pin plug bolted in front of those. The diagram showed a 4 pin and skinny 3pin. Even if it would only use 3 it would have to be the size of the 6 pin to work.
Expert:  Dan replied 1 month ago.

So your cable plugs in but it just wont communicate. There could be a problem with the cable itself, the ECU, the datalink harness of the machine, or a power/ground issue with the ECU on the machine side. Too bad there was not a way to test your dr zx on another machine to see if it will read.

Customer: replied 1 month ago.
I will see if there is a hitachi or Deere near me I can test.
Expert:  Dan replied 1 month ago.

Keep me posted. Since this is a new diagnostic tool, there could be a problem with it.

Expert:  Dan replied 1 month ago.

If your dealer is close by there may be some in the lot you could test.
