1. While not in programming mode, transmit a $20 service request with extra information appended to the
message resulting in an incorrect length and verify negative response ($7F $20 $12).
2. Repeat step 1 while programming mode is active and verify that the negative response ($7F $20 $12).is
sent.
Procedure 2:
1. While in programming mode, transmit a service $20 request message using the functional all-nodes CAN
Identifier ($101) + all-nodes extended address ($FE). Verify that there is no response sent.

Procedure 3:
1. While not in programming mode, transmit a service $20 request message while periodic DPIDs are
scheduled. Verify the positive response and that the scheduled messages are halted.
2. If the node supports dynamic DPIDs, define a dynamic message number via service $2C, and configure
the node to schedule the message periodically via service $AA. Verify that periodic responses are
received. Next transmit a service $20 request to the node and verify that the just-defined periodic
message(s) are halted.
3. Repeat the $AA request to schedule the dynamically defined message, and verify that the format of the
dynamically defined message was not lost after the service $20 request.
Procedure 4: 
(Valid if the send on change DTC logic is supported by the node).
1. While not in programming mode, transmit a service $20 request message while the DTC send-on-change
algorithm is activated. Verify the positive response and that the updated DTC count information is no
longer reported by the node. (This can be done by causing a code to transition to a state that satisfies the
send-on-change DTC status mask, and verifying that no information is reported by the node.)
