Create a Broadcast List
In the following example a broadcast list will be created. The list will also be activated. The list will contain PID $00 $40 (engine rpm) and PID $00 $54 (engine oil pressure). The information will be requested in 2 second intervals from the EMCP II GSC. The list will then be deactivated.
Create a Broadcast List - IID 13: 500013150258040020004000540000000000 0000000000000086IID 13 - Used to create a broadcast list. A total of eight lists is allowed by the CCM. This example assumes list number 2.
