Relationship between Event Codes and Error Codes
In addition to the event codes that indicate errors, the function modules and Units have their own
error codes. If there are corresponding event and error codes, you can tell what the other code is if
you know either one of them. This allows you to know when the same error is being given when you
check errors with more than one method.
The following table shows the relationship between the error codes and event codes.
