BIT ERROR CODES
Every BIT test is assigned a unique numerical value in the form xx.xx. Operators should use the BIT error code
tables to reference the faults code and review the recommended actions. Some failures may not be isolated by a
BIT, in which case maintenance intervention is required to diagnose and isolate the fault.
