Also, try to search for the maintenance object name in the maintenance manuals instead of the specific error. The same error number can be in the manual many, many times.
For example, for this error:
01A01 UDS1-BD 1281 03/25/04:06 04/12/13:48 255 0 4 a y
Look in the maintenance manual for "UDS1-BD" first. Once you find that section, you can usually just scroll down for the list of possible errors associated with that maintenance object.
Hope that helps.
