However, some of the control systems such as SRS, IMM or BCM may not support DTC
Read and Erase functions. Some control modules may require G-scan2 to communicate with
the system individually to read the DTC.
In both cases, G-scan2 is unable to show the number of DTCs in the System Search report,
not because of its fault but because the system is designed in that way.
To avoid misunderstanding, G-scan2 indicates such exceptional cases with the “ - “ and “ -> ”
symbols.
Symbol Description
-
The system does not support DTC reading function.
->
The system needs to communicate individually. Please select
the system from the menu and check the DTC individually.
1.3. Special Functions Availability
Depending on the vehicle, if a detected system supports the “Special functions”, then G-
scan2 indicates it with the star marks.
