8.15.7 Node Verification Procedure.
Procedure 1:
1. Request message length test: Send a physically addressed TesterPresent ($3E) request message with an
invalid message length (not equal to 1) and verify that a negative response message with response code
$12 is sent by the node (ECU).

service $A5).
2. Send functionally addressed TesterPresent ($3E) request messages with an invalid message length (not
equal to 1) and verify that no negative response message is sent by the node (ECU).
3. Verify that the node (ECU) sends a ReturnToNormalMode positive response message between P3
C 
and
P3
Cmax
.
Procedure 3: 
(Uses Functional 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 functionally addressed TesterPresent ($3E) request message using the AllNodes CANId
($101) + AllNodes extended address ($FE).
4. Verify that no 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.
