Thank you sir, I'll check to see if that's the case with my 5570.
Had the same issue with my 1533 (obviously a much smaller machine) and found it was tucked into the wiring harness on the left side of the engine. With everything being painted black including all the wiring, it was difficult to find. Mine uses a standard 16 pin OBDII connector. I also have a flashing MIL light, but the code is evidently an OEM specific code and I don't have a list and I haven't found another vehicle using a Bosch ECM which may reveal the code description. I am able to pull live data, most of which makes sense. I say mostly, because some of the live data refers to sensors not on this machine. In a perfect world, the software would be available at a reasonable cost and we could diagnose problems without a trip to the dealer. I have tried a few scan tools from basic to higher end, all with the same result more or less. Next step is to capture scope traces for known good sensors for comparison if a problem develops at a later date.
