When dealing with customer complaints of excessive condensation and/or water within the headlamp unit, first determine if all the bulb sockets (including O-ring), seals and covers are present and correctly installed. In most cases you will find that the Bulb Seal No. 1 (A) or HID Bulb Seal No. 1 (B) and Bulb Seal No. 2 (C) socket covers have not been correctly installed or are missing due to improper prior repairs (i.e., customer replacing the headlamp bulbs or body shop not transferring them when replacing the headlamp unit(s) due to a collision). Any damage caused by missing socket covers, HID module seal (D), or missing bumper brackets (E) is not covered by warranty policy.
09-035-17-30802017-10-04. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. 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.
01-011-17-33642017-10-04. Service bulletin. ENGINE; ELECTRICAL SYSTEM. If a customer brings their vehicles in with DTC P2183:00 stored, repair the vehicle using the following Repair Procedure and Caution. P2183:00: ECT sensor No.2 circuit range/performance problem. This is caused by the ECT sensor No.2 located near the bottom of the radiator getting wet and water entering the part due to insufficient water resistance. To correct this issue, the water resistance of the ECT sensor No.2 has been improved.
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.
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.
SA-046-172017-08-25. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. An update to the MAZDA CONNECT system is now available for download from the Mazda Global Service Support (MGSS) system. The new version number is 59.00.502. Please refer to TSB 09-017/17 for a list of improvements to the system.

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.
SA-061-172017-08-10. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. In an effort to achieve a higher level of Customer Experience and retain the value of Mazda's vehicles, MNAO Warranty Operations is© 2017 Mazda North American Operations, U.S.A. allowing all Mazda dealers to utilize a third party, SPECMO Enterprises, Inc., for Instrument Panel Cluster (IPC) odometer setting service.
