    4. Is the measured resistance within specification?

      YES 

      • Substitute with a known - good ECM/PCM and check for proper operation.
      • If the problem is corrected, replace ECM/PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
      NOTE: There is a memory reset function on scantool 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

      NO 

      • Substitute with a known - good HO2S (S2) and check for proper operation.
      • If the problem is corrected, replace HO2S (S2) and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
