Error Byte Definitions
The Error Bytes described in this section store the results of the firmware-driven checks built into the
RGA ECU. Use the Error Reporting commands to query the value of the bytes.
Important : No errors are present as long as all bits in the Error Bytes are cleared.
The RGA Windows software supports all the Error Reporting commands and reports the errors
detected based on their Error Codes.
The RGA Troubleshooting chapter identifies the different problems based on their Error Codes and
suggests possible causes and solutions.
STATUS Error Byte : General Status byte. Each bit corresponds to a different type of
internal check.
