If certain failures occur, the matching error codes will be stored in the EEPROM. These error codes will be displayed in parameters 1, 2, and 3. The first

failure error code will be stored at parameter 1 and the second failure error code will be stored at parameter 2. Parameter 3 will be updated to display the

most recent failure occurred in the chassis. If a failure of a bus IC occurred, the normal acknowledgment checking of that bus will be disabled in the

service mode and the address of that IC which failed will be stored in one of the error code parameters. After every repair is done to the chassis it is

recommended to check the error code parameters, and reset them back to value 0.
