7.2.3 ConditionsNotCorrectOrRequestSequenceError ($22, RC_CNCRSE). 
This response code indicates 
that the requested action will not be taken because the ECU prerequisite conditions are not met. This request 
may occur when sequence sensitive requests are issued in the wrong order. 
Example:
The ECU shall send this response code in: 

Case #1:
The tester has sent a known and supported request message at a time where the ECUs 
conditions to execute the requested service are unsafe or too critical to perform the requested action. 

Case #2:
The tester has sent a known and supported request message at a time where the ECU has 
expected another request message because of a predefined sequence of services. A typical example of 
occurrence is the securityAccess service which requires a sequence of messages as specified in the 
message description of this service. 
7.2.4 RequestOutOfRange ($31, RC_ROOR). 
This response code indicates that the requested action will not 
be taken because the ECU detected a data byte(s) in the request message which attempt(s) to substitute (a) 
value(s) beyond its range of authority (e.g., attempting to substitute a data byte of 111 when the data is only 
defined to 100). 
Example:
The ECU shall send this response code in case the tester has sent a request message including 
data bytes to adjust a variant which does not exist (invalid) in the ECU. This response code shall be 
implemented for all services which allow the tester to write data or adjust functions by data in the ECU.
