InitiateDiagnosticOperation ($10) 
to generate the wake-up (functionally
addressed to gateway ECUs only). This is necessary because the gateway ECU(s) has (have) been
reset and might have lost the internal information about keeping a wake-up signal line asserted on
another subnet on the vehicle.
Note: 
The tester must allow at least 500ms after issuing a wake-up before transmitting any diagnostic
request message (including tester present) to allow the ECU to process the wake-up and transition to
a communication active state. Refer to paragraph 6.1 for wake-up requirements.
28
Start sending 
TesterPresent ($3E) 
periodic messages to all nodes - all links as needed (using the
AllNodes CANId and AllNodes extended address).
29
The tester must now issue a request for service 
ReadDataByIdentifier ($1A) 
with 
DID $B0 
in order to
perform a relearn of the diagnostic address and CANIds. This is necessary because an ECU which
was programmed and performed a reset after the ReturnToNormalMode ($20) service from Step 23,
would now use its permanent CAN Identifiers. This step is performed automatically prior to the
execution of utility file driven diagnostic service (e.g., Step 25) following the ReturnToNormalMode
($20) service.
30
The 
WriteDataByIdentifier ($3B) 
service may be used to program option content information into
SPS programmable ECUs which were just programmed.
Note: 
The tester may send a service $04 request to clear DTCs at the conclusion of the programming event.
This is typically done at the conclusion of module programming in the vehicle assembly plant.
