In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer. NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealer?s responsibility to comply with Federal, State, and local laws concerning odometerand related documentation requirements when providing a repair or replacement. Mazda vehicles are manufactured with tamper-proof speedometers. When a speedometer is replaced, the new speedometer will read zero (0) miles. This procedure is extremely important to accurately represent actual vehicle mileage. Prior to speedometer removal, complete the information required on the ?SpeedometerReplacement Label?.Labels can only be ordered through Mazda eStore. In an effort to achieve a higher level of Customer Experience and retain the value of Mazda?s vehicles, MNAO Warranty Operations is allowing all Mazda dealers to utilize a third party, SPECMO Enterprises, Inc., for Instrument Panel Cluster (IPC) odometer setting service.With the use of SPECMO?s services, a Mazda dealer can get the odometer setting updated to reflect the correct mileage at the time of replacement for both warranty and customer pay repairs, therefore resulting in a higher level of customer satisfaction. Since odometer setting service is not part of the warranty repair, it is not warrantable nor required, but optional. However, Mazda Warranty policy provides after- warranty assistance (AWA) or DSA that can be utilized to cover this service expense.

SSP982017-09-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL. Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014-2015 Mazda3 vehicles, equipped with MAZDA CONNECTTM System.This SSP98 supersedes MSP41 and Service Bulletins 09-034/13 and 09-006/14. The latest version of software for the Connectivity Master Unit (CMU) is now available. By updating the CMU software, the features and functionality of the MAZDA CONNECTTM system will be further enhanced. Dealers are to reprogram the CMU software using a USB memory stick to incorporate further improvements in the MAZDA CONNECTTM system. The reprogramming operation must be performed at no charge to the vehicle owner.
MT-010-172017-08-25. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may claim that it is impossible or difficult to view the Active Driving Display, even if the position of the display is adjusted through the Settings screen. This is caused by an incorrectly learned zero-point (closed position) of the Active Driving Display. The main reason this happens is because an object (e.g. gloves, paper, etc. ) was placed in the storage area where the mirror and optical receiver are housed. If an object is detected (i.e., jammed) when the Active Driving Display closes after switching the ignition OFF, the system determines this as abnormal and stops the closing operation, leaving the Active Driving Display in an open position. When the engine is started the next time, correction of the zero-point is automatically performed. If the object is still in the storage area during the correction, the system learns the incorrect position as the zero-point. As a result, the zero-point position largely deviates from the standard position; therefore, it becomes impossible to view the Active Driving Display from the normal view position.
MT-015-172017-08-10. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT ADAPTIVE/MOBILITY. Some customers may complain about the following MAZDA CONNECT Temperature Warning message: Display is too Hot. Screen performance may be decreased until it cools. The warning message displays when the MAZDA CONNECT screen temperature is above 176 degrees Fahrenheit (80 degrees Celsius).
SA-063-172017-08-10. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL. Some customers may complain about the "wrong" phone is connected to the infotainment system. MAZDA CONNECT bluetooth will connect all profiles to devices in order of priority if the last device is not available. This concern may be a normal operation of the CMU connecting to available devices on start up.
01-003-17-3297a2017-08-10. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES; EQUIPMENT:ELECTRICAL. When the engine is started for the first time after parking overnight in cold weather (below freezing), some vehicles may exhibit the check engine light on with DTC P0451:00 (Fuel tank pressure sensor: sensor characteristic malfunction) stored in memory.This concern may be caused by an increase in discharge resistance due to water accumulated and frozen in the canister vent hose.
09-030-13-28502017-08-10. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. When replacing the tuner and amp unit (TAU) with a new one for any reason, a call must be made to inform Sirius XM Dealer Support (1-800-852-9696) of the Radio ID (of the new TAU) and the vehicle VIN as soon as possible. If the customer has already signed-up for a SiriusXM satellite radio subscription, ask the customer to renew the subscription with the new Radio ID. Otherwise, the satellite radio activation will be refused. Even if the customer has not signed-up for a subscription, this information is important in case the customer wants to sign-up at a later date.
09-034-13-28312017-08-10. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL. An updated version of the software for the Connectivity Master Unit (CMU) has become available.
