A malfunction is detected by using a checksum technique for verifying data. The digital data is composed of zeros and ones. A checksum is the total of all ones in a string of data. By comparing the checksum value with a stored value, a malfunction can be detected.
By comparing the checksum value with a stored value, if the both data are not equal , TCM sets DTC P0601 .
