7. If applicable, send a request to an ECU with a manufacturers enable counter = $00 and a vulnerability flag
< $FF, with a range of valid and non restricted addresses that includes at least one secure address. Verify
negative response ($7F $23 $31).
8. If applicable, send a request to an ECU with a manufacturers enable counter > $00 or vulnerability flag =
$FF when security has not been accessed (SecurityAccess ($27) request has not been sent), with a range
of valid and non restricted addresses that includes at least one secure address. Verify negative response

9. If applicable, send a request to an ECU with a manufacturers enable counter > $00 or vulnerability flag =
$FF when security has been accessed (SecurityAccess ($27) request has been sent), with a range of valid
and non restricted addresses that includes at least one secure address. Verify positive response.
10. If negative response code $78 is supported by the ECU, then create the conditions under which the ECU
should return the $7F $23 $78 response and verify that proper response is sent. Repeat for each possible
reason an ECU would send the negative response with response code $78.
11. If negative response code $22 is supported by the ECU, then create the conditions under which the ECU
should return the $7F $23 $22 response and verify that proper response is sent. Repeat for each possible
reason an ECU would send the negative response with response code $22.
