I have power at my OBDII port in my 04 Rodeo but no connectivity to the ECU. Is there a fuse in line between the port and the plug somewhere? I've examined all the fuses under the hood and in the fuse compartment and they're all good.

+12 Vdc to the DLC is on Pin 16. On my 01 & 02 Rodeos and on 04 Axiom the power to pin 16 is supplied by a 10 Amp fuse labeled "Horn" I expect a 04 Rodeo would be the same.

Thanks, 10A Horn fuse blown, not sure what caused it, but can get inspected now. :)
