i installed a TU600-25 trackunit in november 2023 in a 2023 SANY SY50U excavator, with can connected to can3, now, a year later, when i start the machine, 10 seconds after starting the engine, a P802 code appears on the screen. i unplug the trackunit, start the machine, no codes, i replaced the module, no P802, until i activate the device in verify, then P802 reappear on the screen. i double checked the wiring, i’m connected on CN-201F deutsch plug, canh and canl are on the right wire, i have 60 ohm so it’s non-terminated. and voltage is 2.3v and 2.6v. seems that we have the same issue on SY60 and SY80 models. anyone came across similar issues?
