Any idea what year and engine...???

No such codes as SC44 and SC55 to my knowlege.... Could you be mistaking a "0" for a "C"....

SO44...Lift/dive signal fault
S055...remote resistor hold side short to ground/open circuit
...RSS resistor module short to ground/open circuit

The "S0" codes are for the RTD/RSS suspension system control system. The lift/dive signal would be from communications with the PCM.


The "PCM?" is just the onboard diagnostics system prompting you for the next level of the diagnostics system. Answer yes or no with the HI or LO buttons to answer the prompts...or press OFF several times to exit the system.
