## NHTSA's summary

Detroit Technical Service Letter for Fault Codes SPN 2659/FMI 0 and SPN 3216/FMI 20 on DD16/GATS 2.0 Only. For vehicles equipped with DD16/GATS 2.0, there has been an increase in the frequency of fault code 2659/0. This is due to a calibration issue in the current MCM software \(19.1.1.3 and 19.2.1.4\). New software will be released at a later date to address this fault.
