Po1860 will cause a false p0741. The diagnostics for p0741 requires that
po1860 is not a current code.

Po1860 is the Torque Converter Clutch circuit.
It means that the converter isn't locking up. Your mileage will suffer, but running without the converter locked will cause excessive heat and eventually will kill the transmission...that would be what i'd be most worried about...
there could be a number of reasons for this...could be as simple as the tcc solenoid, or as complex as the converter itself failing...which would mean you'd have to drop the cradle and seperate motor and trans to replace the converter...

What does mil cmd fail mean?


MIL is your malfunction indicator lamp, (check engine light)

CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer

check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.

A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective compute
  • P1105MAP/BARO Pressure Switch Solenoid Valve
  • Check and clean the MAP sensor, or replace.
  • P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
  • Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.

Did not pass state inspection (vehicle)


First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

Can't pass state inspection, changed EGR valve already, next?


I suggest quit hunting for maybes and rent an OBD code reader which ends up being free when you return it to the auto parts store. Connect it and find out what is causing the CEL condition. Normal issues are the O2 sensor, or sensors in the system.
