Data stored Details
Self-diagnostic error code 1 The maximum of 16 types of error codes are stored into SD10 onwards
when the diagnostics detects an error.
Self-diagnostic error code 2
(The same error code as one already stored in SD10 onwards is not
Self-diagnostic error code 3
stored). The 17th error code onwards are not stored. Also error codes
are not stored when 16 types of error codes have already been stored
Self-diagnostic error code 4
into SD10 to SD25.
