1 - 22Chapter 1 Troubleshooting4. Error Code FIP4.1 Level 1 FIPFIP1.1 NVM Error*1: Though some kind of foreign noise would be possible cause, go to [FIP2.19 Electrical Noise] andcheck, to make sure.Step Check Yes NoPossible causative parts:HVPS/MCU (PL12.1.19)1 Does Error occur when the power is turned ON? Go to step 4. Go to step 2.2 Does Error still occur when the power is turned OFF andON again? Go to step 4. Go to step 3.3 Does Error still occur after several ON/OFF procedures ofthe power? Go to step 4. End of work *14Checking HVPS/MCU non-volatile memory setup modeIs non-volatile memory setup mode accessible?Checks by Chapter 2 Diagnostic [DC301 NVM Initialize].Go to step 5.ReplaceHVPS/MCU.(RRP12.10)5Checking NVRAN for data setupAre all NVRAM data set appropriately?Checks by Chapter 2 Diagnostic [DC131 NVM Read/Write].Go to step 7. Go to step 6.6Checking Error after changing HVPS/MCU data setupChange NV RAM data to the correct setup value, and thenturn the power ON again. Does Error still occur?ReplaceHVPS/MCU,then go to step 7.(RRP12.10)End of work7 Checking after replacing HVPS/MCUDoes Error occur?Go to FIP2.19Electrical Noise. End of work
