• Code: E350-0002
• Description: Fault in the soft ID PCB/function
  The value of the check sum area of all data read from the soft ID PCB and the result of checksum computation do not match.
• Remedy: Turn off the main power, and replace the soft ID PCB. If the remedy fails, replace the soft ID PCB.

• Code: E350-0003
• Description: Fault in the soft ID PCB/function
  The values in the soft ID check sum area of FRAM, SRAM1, and SRAM2 and the result of a check sum computation differ.
• Remedy: Turn off the main power, and check the connection of the soft ID PCB. If the remedy fails, replace the soft ID PCB.

• Code: E350-3000
• Description: Fault in the soft ID PCB/function
  While an E350 error is backed up, the value of the check sum area of all data read from the soft ID PCB and the result of check sum computation do not match.
• Remedy: Turn off the main power, and check the connection of the soft ID PCB. If the remedy fails, replace the soft ID PCB.

• Code: E351-0000
• Description: There is an error in the main controller PCB (sub).
  At start-up, there is an error in the communication between main controller PCB (sub) and the main controller PCB (main).
• Remedy: Turn off the main power, and replace the main controller PCB (sub). If the result is not good, replace the main controller PCB (main), and turn on the main power.

• Code: E354-0001
• Description: Serial No. mismatch
  All the values of the soft ID 8 digits of SEEPROM are 0x00 or 0xoff.
• Remedy: Replace the soft ID PCB.

• Code: E354-0002
• Description: Serial No. mismatch
  In the absence of an error, the soft ID PCB has been replaced with a new PCB and, in addition, the following conditions exist at the same time: - the soft IDs of the following pairs are not identical: SEEPROM and SRAM1, SEEPROM and SRAM2, SEEPROM and FRAM. - FRAM is not of the initialization pattern (i.e., the value of the check sum area is '1' but the result of computation of the counter area check sum is not '1'). - the soft IDs of the following are all identical: SRAM1, SRAM2, SRAM.
• Remedy: A mistake is likely to have been made in the course of counter PCB replacement; as a result, E355 is likely to have occurred thereafter, not permitting recovery despite an attempt to reset E355.

• Code: E355-0001
• Description: Serial No. mismatch PCB.
  The soft IDs of the following pairs are not identical and, in addition, any of the following conditions exist: SEEPROM and SRAM1, SEEPROM and SRAM2, SEEPROM and FRAM. - FRAM is of the initialization pattern (i.e., the value of the check sum area is '1', and the result of check sum computation of the counter area is '1'). - the soft ID of any of the following is not identical: SRAM1, SRAM2, FRAM.
• Remedy: Reset E355 (if the error occurs in the middle of repair operation). At times, E355 cannot be reset (intentionally designed in such a way to prevent illegal replacement in the field).

• Code: E400-0001
• Description: There is a DF communication error.
  There is a check sum error.
• Remedy: Disconnect and connect the harness connector; then, replace the reader controller PCB or the ADF DC controller.
