Is This The Right Diagnostic Cable ?

    • Thanks Thanks x 1
  2. Thanks to @chrisw and numerous threads on here I have managed to get the diagnostic software up and running. I can power up various circuits, have played with the flashy lights on the dash and reset the Pin code.

    I did notice that my Home Screen differs from those shown in forums & on YouTube as it doesn’t give me the option to choose the bikes year, just any bike or M3C. Is this normal?

    Also, when I choose the DTC tab to look for fault codes, the following appears:

    Despite various searches, I can’t seem to fathom what these lines mean or if I should do anything about it. Anyone have any ideas?
     
  3. This is not part of the JPDiag software I have experience of.
    Do you use the JPDiag Forum. Lots of answers on there.
    Looks like JP has improved the software so you do not have to select bike.
    I have found that
    7E0 is main ecu
    7E2 is BBS ecu
    So you probably have to select the ECU for DTCs
    From what I have read another of the ECUs could be the dash

  4. I am on the JP forum, will put a post up later. So the button ‘DTC on 7E2’ should bring up any fault codes on the BBS and the ‘erase 7E2’ button resets the codes? Makes sense.

    I haven’t pressed either for fear of messing up the settings
     
  5. Thanks once again @chrisw you are bang on.

    DTC found several faults on 7E2.

    7E0, 7E1, 7E3, 7E4 and 7F0 had no answer.

    Have now reset 7E2 and will put a few miles on the bike at the weekend and run the test again to see what faults, if any are current.

  6. So i cleared the fault codes on 7E2 and then took the bike for another test run to see if i could replicate the cutting out problem and then subsequently run the diagnostics again to see what pops up.

    I took the exact same test route and as last time and the bike was running like a train, no problems whatsoever. Then, like clockwork, the engine light came on and the bike cut out in almost the exact same place as it had done the previous two times (around the 35 mile mark) Turned of the ignition, listened for the main relay to click off, turned her back on and she fired up and ploughed on home as if nothing had happened.

    Having rerun the diagnostics once more, the following codes pinged Melcodiag:

    P0600 is prevalent on various Google searches and suggests low battery voltage, poor connection on the loom or (worst case) a faulty ECU. The first 2 I can check myself.

    Moving on to the second code, C1003, I can’t seem to locate a Ducati specific diagnosis for this code (Other manufacturers suggest maybe MAP sensor) Has anyone had this code before? Is it connected to the P0600 code? Can it be successfully rectified without resorting to a main dealer visit?

    I’m glad I rode the bike on the road a bit to shake out the nuances prior to tracking it. I doubt this fault would have appeared in a 20 min track day session.

  7. P0600 could be a CanBus error. Canbus is transmitted over just two wires. Identify the two wires and check for continuity.
    C1003 is possibly linked to the exhaust gas recirculation valve.
    If you download the handbook from the Ducati site the wiring diagram is at the end. It is in PDF so you can zoom in.
