Some vehicles equipped with MAZDA CONNECT may exhibit the following oil maintenance monitor concerns on the center display: The wrench light (Oil Change Due message) cannot be cleared using MAZDA CONNECT/Applications/Vehicle Status Monitor/Maintenance reset menu. The wrench light (Oil Change Due message) is displayed before the oil change is due. Vehicles with multi-information display Vehicles without multi-information display This is caused by only one reset procedure being performed when the oil is changed, usually using the center display. Two reset procedures are required, one is using the trip meter switch to reset the powertrain control module (PCM) and the other is using the center display to reset the connectivity master unit (CMU). To correct this issue, the CMU software has been modified so that the oil maintenance monitor reset operation on the center display resets both the CMU and the PCM at the same time. With this change, there set operation using the trip meter switch is now unnecessary.
