P160C - CONTROL MODULE SOFTWARE PERFORMANCE

Description:  Indicates that the powertrain control module (PCM) internal central processing unit (CPU) has encountered an error. The PCM monitors itself and carries out internal checks of its own CPU. If any of these checks returns an incorrect value, this DTC sets.
Possible Causes: 
  • Aftermarket performance products
  • Low voltage on the vehicle power (VPWR) circuit
  • Check the PCM VPWR circuit for an intermittent condition
  • Keep alive power (KAPWR) circuit to PCM concern
  • Software incompatibility issue
  • PCM programming error
  • Damaged PCM
Diagnostic Aids:  Reprogram or update the calibration. Check for other DTCs and diagnose those first. Check for aftermarket performance products before installing a new PCM. Clear the DTCs, repeat the self-test. If the DTC is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) , Programming the VID Block for a Replacement PCM.
