dataRecord[] 
This is the portion of the response message which contains the data stored in the ECU memory location(s) 
of the requested DID. The length of this field is dependant upon the dataIdentifier requested.
 
8.4.4 Supported Negative Response Codes (RC_). 
The following negative response codes (Table 72) shall 
be implemented for this service.

Description

Mnemonic 
12 
SubFunctionNotSupported-InvalidFormat 
This response code shall be sent if the request message does not have a DID 
number after the Request Service Id, or if additional data bytes are included 
beyond the DID byte.

SFNS-IF 
22 
ConditionsNotCorrectOrRequestSequenceError 
This response code shall be sent if the operating conditions of the ECU are 
such that it cannot perform the required action (e.g., the data for a DID is 
stored in EEPROM and an EEPROM failure has occured). This response code 
is not intended to be used if the ECU conditions are such that the request 
temporarily cannot be performed (e.g., the data to be retrieved temporarily 
cannot be read from EEPROM because another application task is currently 
writing to EEPROM). Response code $78 is used when conditions are 
temporarily not met. If this response code is supported by a node, the 
reason(s) to generate this return code must be documented in the Component 
Technical Specification (CTS).

CNC-RSE

RequestOutOfRange 

This code shall be sent if the dataIdentifier value requested is not 
supported by the device.

This code shall be sent if the dataIdentifier is secured and the ECU is not in 
an unlocked state.
