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.
090181733512017-09-27. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may complain that the ambient temperature display is not accurate, or it takes too long for the display to show actual temperature. When you encounter a customer with this concern, first verify the condition when the customer noticed this symptom. If the condition is similar to the following "CONTROL LOGIC OF AMBIENT TEMPERATURE" or "DIFFERENCE BETWEEN THE TEMPERATURE DISPLAY AND OTHERS", advise the customer that this is a normal characteristic of the vehicle and not a malfunction. If the condition does not meet the following and the sensor malfunction is suspected, make sure to inspect the sensor according to MGSSonline or Workshop Manual (section 09-22 AMBIENT TEMPERATURE SENSOR INSPECTION). Replace the sensor only when it fails the Workshop Manual inspection.
090171733462017-09-27. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. All Mazda Connect vehicles in new car inventory must be updated to this software version listed below in this TSB as part of the New Car Ready Step 3 process. Make sure the new vehicle specialist receives a copy of this bulletin. Some vehicles may experience the symptoms mentioned below, which can be fixed with the latest software update (Version 59.00.502or later). NOTE: For CX-9 with version earlier than 59.00.441, the tachometer function has been removed from the Active Driving Display as part of Mazda?s continuing efforts to improve safety and reduce driver distraction. Please explain this to the customer before updating the software.
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.
