Pattern
D
Error Condition
The CPU of the BiCU detects an error during communication with the EEPROM on the BiCU.
Major Cause
1. EEPROM is not connected properly.
2. EEPROM is defective.
3. BiCU is defective.
Solution
1. Remove the EEPROM from the IC socket, and then set it again.
*If the EEPROM lead is bent or it was set in the reverse (wrong) direction, then it would be
damaged.
2. Replace the EEPROM.
3. Replace the BiCU.
