    4. Is the measured resistance within specification?

      YES 

      • Substitute with a known-good ECM/PCM and check for proper operation.

      NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM/PCM.
      Before or after testing ECM/PCM on the vehicle, use this function to reuse the ECM/PCM
