Some customer using "Flexible" setting for Oil Change in the maintenance monitor may notice that the oil change due notification will not work due to improper control logic of the PCM. The PCM clears the TRAVELED DISTANCE at the wrong time while the ELAPSED DAYS and the DETERIORATION DETERMINATION work as designed. To correct this issue, the control logic of the PCM has been changed. This TSB is applicable for the following cases. The oil change due notification does not come on, even after mileage exceeded 10,000 miles. Oil life in the center display is still less than 40% even though the mileage exceeded 7,000 miles. To display "Flexible" setting and "Oil life" on the center screen, select the "Applications" screen, "Maintenance", then "Oil Change" tab. For complete details, refer to the the instructions on MGSS (MAINTENANCE MONITOR OPERATION PROCEDURE).
