SVAI Codes
Codes 7E or other than 00 Appear
 

SVAI CP Codes
  These appear during POST. Most are not errors, and will scroll right on by. Any errors will be preceeded and followed by a "EE"

7E Appears on SRC double digit display
   Turn key to MAINT MODE. The error codes will scroll through the display. Note the codes for later reference. For a description, go to the SVAI CP MM table.

SVAI Stops with a Code other Than 7E or 00
   Note the error code.

Run Time Error Codes
   If an error occurs during system operation, you will get a checkpoint code as follows:
 CP  Description Recommended Action
 C0  I/O Channel Check Power Off then On. If C0 appears, have system serviced.
 C1  Temperature Check System is overheated.Check filters.
 C2  Power Supply Check Low voltage on DC backup connector, battery or fan failure.
 C3  ECC Multibit Check Power Off then On. If C3 appears, have system serviced.
 C4  AC Power Check Momentary AC failure. Normal ops will continue.
 C5  Watchdog Timer Timeout Power Off then On. If C5 appears, have system serviced.
 C6  Arbitration Timeout Power Off then On. If C6 appears, have system serviced.
