ENDFUNCTION
This function handles the sending of UUDT response messages for service $A9 requests with the
sub-parameter set to $82. The function shall be executed in a background loop at a rate which satisfies the
UUDT timing requirements specified in the Service Description section of this diagnostic service
BEGINFUNCTION Send_On_Change_DTC_Count( )
/************************************************************************************
* Handle Message $82 Steady State “sendOnChangeDTCCount”
* This background algorithm is halted when any of the following conditions occur:
* 1. Tester transmits service $20 request to return to normal mode
* 2. The node is powered down
* 3. Tester stops sending service $3E tester present requests
* NOTE: this algorithm is intended to be run in parallel to internal node-resident
