and "OLd" in "Detailed Information Mode 2", refer to the following:



"SyS" is displayed before the detailed codes (detected as a result of "System Check
Result Request") are displayed.



"COdE" is displayed before the detailed codes (detected as a result of "Diagnostic
Memory Request") are displayed.

HINT:



The response to "System Check Result Request" is the current information given
from each ECU as a result of the system check.



The response to "Diagnostic Memory Request" contains the information
received from each ECU or stored in each ECU in the past.



The response to "Diagnostic Memory Request" is the output DTCs as a result of
the diagnostic memory check or the DTCs received from each ECU.



"System Check Result Request (SyS)" is displayed first, and then the logical
address and DTC appear in order.



"Diagnostic Memory Request (COdE)" is displayed first, and then the logical
address, DTC, sub-code, connection check number, and the number of
occurrences appear in order.
