8.2 InitiateDiagnosticOperation ($10) Service. 
This service allows the tester to perform the following tasks:
•
Disable the setting of all DTCs while the tool continues to perform other diagnostic services.
•
Allow ECU DTC algorithms to continue to execute while the DeviceControl ($AE) service is active.
•
Request a gateway ECU to issue a wake-up request.
8.2.1 Service Description. 
The disableAllDTCs ($02) and enableDTCsDuringDevCntrl ($03) levels of this
service require that a TesterPresent ($3E) message be sent within the P3 timing window in order to keep the
functionality active.
If a sub-function parameter has been requested by the tester, which is already running, the ECU shall send a
positive response message. If the ECU sends a negative response message to a request for this service, any
levels active due to previous requests shall continue to remain active.
