Hallo from Germany,
on my 5.9 ZJ i got half the problem.
Engine running imediately and fin. Bit no needle in the Cockpit is moving, all on zero, and turning on ignotion no Engine Check Light. Bulb ok, and my Instrument Cluster is checked also in an 5.2 Z.
ASD-relay also switched. Most Sensors disconnected, no change. And on my OBD2 Adapter I see Instrumentsinformation and live datas. The CCD has 2,3 V both channels, Ground Good, 12.8 V from battery. Any ideas?
best regards and a nice day
Marcus
