c) Viewing STATUS CODE/SUB STATUS CODE
How to view the area indicating "STATUS" in Network menu is shown below. This area comprises of 4 bytes and can hold 4 error states which have
occurred recently. The figures which are indicated in 1st byte area in Figure represent the oldest error among 4 ones. The figures which are indicated in
4th byte area represent the newest error. Numeric figures indicated in each byte represent a SUB STATUS CODE number. In other words, if "STATUS"
indicates 00021509, the error which occurred last is "STATUS 09" and the one before it is "STATUS 15", and the one before the previous one "STATUS
02". In this case, as the 1st byte is 00 (no error), it can be found out that the "STATUS 02" is the oldest error. Also, if all 4 areas (4 bytes) have been
used, an item of another error which occurs next would not
be registered. As the oldest error is generally the main reason in most cases, take note of this value.
How to view each SUB STATUS CODE is indicated in the followings. Although SUB STATUS CODE also comprises of 4 bytes, SUB STATUS CODE is
2nd byte. See the appendix for details of SUB STATUS CODE.
