7.2.10 VoltageOutOfRangeFault (High/Low) ($83 RC_VOLTRNG). 
This response code indicates that the 
voltage is out of the acceptable range at the primary power pin of the ECU. 
7.2.11 GeneralProgrammingFailure ($85 RC_PROGFAIL). 
This response code indicates that the ECU 
detected an error when erasing or programming a memory location in the permanent memory device (e.g., 
Flash Memory). 
7.2.12 DeviceTypeError ($89 RC_DEV_TYPE_ERR). 
This response code indicates that the ECU detected an 
incompatibility between the programming algorithm downloaded and the permanent memory device type. 
Example:
In this example, an SPS programmable ECU can be manufactured with a flash memory device 
which can come from two possible suppliers. As such, the programming algorithms for each flash device are 
contained in the routine section of the utility file. When the programming algorithm is downloaded into the ECU, 
it checks for the type of flash device present. If the routine is not compatible with the flash device, a negative 
response message is generated with this response code. 
7.2.13 ReadyForDownload-DTCStored ($99 RC_RFD-DS). 
This response code indicates that the ECU is 
ready for the download of data but the checksum of flash or EEPROM has resulted in a DTC being set 
(reference service $34).

7.2.14 DeviceControlLimitsExceeded ($E3, RC_DCLE). 
This response code indicates that one or more of 
the ECUs internal device control limitations/restrictions have been exceeded and that all active device control 
commands have been terminated. This response code requires two additional data bytes to be appended. The 
additional data bytes identify the specific cause of why the ECU has aborted the device control requested by 
the tester. A GM Corporate list is included in Appendix 
A
of this document. This type of reject message can be 
sent any time a limit has been exceeded, not just in response to a request message (see examples below). 
Example #1:
An Anti-lock Brake System (ABS) controller would not want to allow a tester to release the 
brakes if a vehicle was moving down the road. If the ABS controller sensed that the vehicle was moving above 
a calibrated threshold and a device control command was received to release the brakes on a given wheel, the 
node would reject the request and provide this return code in the reject message. 
Example #2: 
The vehicle is not moving and the ABS controller receives a request to release the brakes on 
one or more wheels. The controller sends a positive response to the request and performs the requested 
command. Shortly after the request is processed, the vehicle begins moving. When the speed exceeds the 
maximum allowed, the ECU will send an unsolicited negative response message with this return code and 
terminates all active device control functions.
