## NHTSA's summary

This ATC is being issued to recalibrate the Engine Control Module \(ECM\) on certain X15 certified engines. A software error may lead to underreporting mileage count on the odometer readings at all operation modes. This field action enables authorized repair locations to calibrate the ECM to the latest revision that may resolve the condition described above and adjust the features. This field action further provides a path for reimbursement of work associated with a prior temporary fix.
