8.19.8 Tester Implications. 
It is recommended that a tester use this service with physical addressing.
Functionally addressed requests for this service may result in unwanted negative response messages from
one or multiple ECUs.
Positive response(s) to this service are formatted as UUDT messages. Since it is possible for multiple UUDT
responses to be sent as a result of a single request, the tester must ensure that it properly handles the timing
requirements outlined in the description section of this service for each available sub-function.
The test device shall send a Service $3E message at least once every P3
C 
ms when using any of the periodic
rates of service $AA, otherwise the device will exit the periodic transmission as if receiving a Service $AA
sub-function parameter $00 request (without DPIDs).

If a tester sends a periodic request with multiple copies of the same DPID in the request, and the DPID (which
was included more than once) is not currently in the PDS, then the tester may receive a $7F $81 (scheduler
full) negative response (based on the number of open items in the PDS at the time of the request).

8.20 DeviceControl ($AE) Service. 
The purpose of this service is to allow a test device to override normal
output control functions in order to verify proper operation of a component or system, or to reset/clear variables
used within normal control algorithms. The tool may take control of multiple outputs simultaneously with a
single request message or by sending multiple device control service messages.
