The first function is the Diagnostic Trouble Code (DTC) check. A DTC is a code stored in the ECU memory whenever a malfunction in
the signal circuits to the ECU occurs. In a DTC check, a previous malfunction's DTC can be checked by a technician during
troubleshooting.

By using these functions, the problem areas can be narrowed down and troubleshooting is more effective. Diagnostic functions are
