Procedure 4: 
(Uses Physical TesterPresent message).
1. Send a service request message to the node using a service that requires a TesterPresent to keep its
functionality active (e.g., schedule periodic DPID via $AA service or use DeviceControl $AE service). Pick
a service where it can be easily verified that the functionality remains active if TesterPresent messages are
sent.
2. Wait 2 s.
3. Send a valid physically addressed TesterPresent ($3E) request message.
4. Verify that a TesterPresent positive response message is sent by the node (ECU).
5. Send no further messages and wait for a P3
C 
timeout to occur. Verify that the node (ECU) sends a
ReturnToNormalMode positive response message between P3
C
and P3
Cmax
. Also verify that the
functionality of the other service has stopped once the ReturnToNormalMode positive response message
has been sent.
Procedure 5:
1. Repeat Procedures 3 and 4 only continue to send TesterPresent messages within the P3
C 
timing window
for at least one minute. Verify that the service activated in step 1 of these procedures continues to function
as long as the TesterPresent messages are sent. After the P3
C 
timeout occurs, verify that the node (ECU)
sends a ReturnToNormalMode positive response message (between P3
C 
and P3
Cmax
) and that the
functionality of the other service has stopped once the ReturnToNormalMode positive response message
has been sent.
Procedure 6:
1. Send a ReturnToNormalMode ($20) request to an ECU and verify the positive response.
2. Send a valid functionally addressed $3E request to the node and verify that there is no response.
3. Wait P3
Cmax 
and verify that no unsolicited mode $20 response is sent.
4. Send a valid physically addressed $3E request to the node and verify the positive response.
5. Wait P3
Cmax 
and verify that no unsolicited mode $20 response is sent.
