ber of error

The first error is requested with 0x00 0x00

Response of the SideStep:

ber of error

Error information

1 byte 1 byte 2 bytes 4 bytes

Attention:

• When a new error occurs, the serial numbering of the listed errors changes.

Error 0 then becomes Error 1, Error 1 becomes Error 2, etc.

• Once the error list is full, the oldest error in the list is deleted.

• If no entry on the required number is found in the error list, an external

diagnostic error with code 0x34 is triggered. In this case the response value

is 0xFF 0xFF 0xFF 0xFF

• With number 0 the current error can be monitored

• If there is no error in the error list, error 0x00 0x00 0x00 0x00 is displayed

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 42 43
