Automotive Diagnostics — Control DTC Setting

The control DTC Setting service is used when the client/Tester needs to stop or resume the server/ECU updating the DTC when a fault occurs. This would be very helpful when the client knows the issue in the vehicle but is trying to root cause by doing some additional experiments.

Important points about Control DTC setting service

• When the client requests the server to switch “OFF” updating the server communication, the server freezes the current values of DTC and suspends any update of the DTC values.
