Description:  The powertrain control module (PCM) monitors the generator load from the generator/regulator in the form of frequency. The frequency range is determined by the temperature of the voltage regulator, where 97% indicates a full load, and less than 6% indicates no load.
Possible Causes: 
  • GENLI circuit short to voltage or ground
  • GENLI circuit open
  • GENRC circuit short to voltage or ground
  • GENRC circuit open
  • ILC circuit short to voltage or ground
  • ILC circuit open
  • Battery-sense circuit open
  • Generator drive mechanism
  • Damaged generator/regulator assembly
  • Damaged PCM
Diagnostic Aids:  Verify the battery voltage is 14.5 volts. Verify the generator/regulator has the correct part number.
