Detail- Error in communication with EEPROM Cause EEPROM failure Installation of uninitialized EEPROM MCU PWB EERPOM access circuit failure
Check and remedy- Check that the EEPROM is properly set. To prevent against loss of counter/adjustment values, record the values with simulation. U2 trouble cancel with SIM 16 MCU PWB replacement
Content Counter check sum error (EEPROM) Detail Checksum error in counter data area Cause EEPROM defective Control circuit hung up due to noise Defective EEPROM access circuit on PCU PWB Check Check EEPROM for proper set-up and To prevent the erasure of counter data remedy and adjustment values, write down the counter data and adjustment values by simulation. (If there is a printer option, execute SIM23-1 and note counter data/adjustment values.) Clear U2 trouble with SIM16. Replace PCU PWB.
