SubFunctionNotSupported-InvalidFormat 
This response code shall be sent if: 

Message length of the request is invalid (less than two bytes). 

Requested sub-function parameter is invalid (not defined or not supported). 

$sub-function parameter = [$01 to $04] and Message length < 3. 

The number of DPIDs in a sub-function parameter $01 request exceeds the 
maximum number of DPIDs supported for one-shot. 

The number of DPIDs in a sub-function parameter $00, $02, $03 or $04 request 
exceed the maximum number of DPIDs that can be scheduled simultaneously in 
the PDS. Refer to pseudo code.

RequestOutOfRange 
This response code shall be sent if: 
Any DPID in the request is invalid (reserved or not defined). This check is not required 
for sub-function parameter $00. Checks for valid DPIDs are performed after the 
checks for message format and sub-function level.

RequestCorrectlyReceived-ResponsePending 
This response code shall be sent if: 
The ECU cannot process the request message and send the first/only UUDT positive 
response within the P2
C
timing requirements.

Scheduler Full 
This response code shall be sent if: 
The PDS would overflow if the request was processed (not enough vacant items in 
PDS to process request).
