A matching response is detected by comparing the command code, and command qualifier within the PKW
response header to those issued in the PKW request header. Since the toggle bit is always reflected by the
gauge, it is also possible to include the toggle bit in the comparison.
The gauge will always respond with command code, and command qualifier, even if the request is not valid.
The response code should be checked before any use is made of the response data. A non-zero response
code indicates that the request failed.
Currently, the gauge responds with a success response code and data of all zeroes for unrecognized com-
mand codes.
Response Code Description
0 Success – The command has been successfully processed.
1 Error – The command referenced an unknown item

type

Error – A request to save a string cannot be performed be-
cause no string data has previously been provided
