02-011-18-34762018-07-02. Service bulletin. TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS. This service bulletin illustrates the conditions when a TPMS warning light may illuminate, why it illuminated and how to properly initialize the system.The Tire Pressure Monitoring System (TPMS) monitors the tire pressure of all four tires indirectly using the data sent from the ABS wheel speed sensors. If the air pressure of one or more tires is too low compared with the specified value (the initial value learned by the system), the system warns the driver with the TPMS warning light in the instrument cluster and a beep sound. To allow the TPMS to operate correctly, it is essential that the TPMS be initialized to learn new conditions whenever a tire related service is performed.
02-010-18-34772018-07-02. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR. Some customers may complain that the steering wheel is off center more than 3° even when driving straight on a flat road.
02-009-18-34722018-07-02. Service bulletin. TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS. Customer complaints have been reported where the TPMS warning light is unnecessarily illuminated because the TPMS initialization was not performed correctly before customer delivery.TPMS INITIALIZATION PROCESS: When any of the services below is performed, BE SURE TO INITIALIZE THE TPMS BEFORE DRIVING THE VEHICLE by pushing and holding the TPMS Set Switch on the dash until the TPMS warning light flashes two times and the warning beep sounds once. The TPMS must be initialized in the following cases: 1. Tire pressures have been adjusted in one or more tires. 2. Tires have been rotated. 3. Tires or wheels have been replaced. 4. The vehicle's battery cable has been disconnected for any reason. 5. The vehicle's battery has been discharged. 6. The DSC HU/CM connector has been disconnected for any reason.
01-012-18-34742018-07-02. Service bulletin. ENGINE. Some vehicles may experience the CHECK ENGINE LIGHT ON with DTC P2610 and P2507 stored inmemory after engine start and room fuse 15A (A) removed. P2610:00: Instrument cluster internal engine off timer performance problem P2507:00: PCM battery voltage low input. As a past malfunction, the customer will not notice it (no warning light illuminated), but the DTC may be found during a vehicle service. P2507 in this situation is only applicable on 2016 and later models. This is caused by the engine being started 3 or more times after a short duration of engine off (less than 15 seconds) with the room fused removed. NOTE: The odometer will display "F0-002" during transport mode (room fuse 15A removed). Transport mode is canceled when room fuse 15A is installed or the vehicle odometer is more than 12.4mi (20km). Vehicles in dealer inventory with this concern should be repaired using the following repair procedure.
00-003-18-34802018-07-02. Service bulletin. SERVICE BRAKES. Mazda North American Operations has approved an additional on-car brake lathe as an option for MNAOauthorized equipment. The Pro-Cut On-Car Brake Lathe has been added to the MNAO authorizedequipment program.NOTE: Accu-turn is still an approved brake lathe, but it is no longer available for purchase from our vendor. IMPORTANT: Rotors must be machined using a Mazda approved on-car brake lathe, or warranty claimsare subject to denial or debit.
09-021-18-34592018-05-14. Service bulletin. STRUCTURE:BODY:TRUNK LID; STRUCTURE:BODY:ROOF AND PILLARS; STRUCTURE:BODY:HOOD. Some vehicles may experience stains appearing on the hood, roof and/or trunk of the vehicle. This concern is most likely to be found in a cold weather areas just after the RAPGARD is removed at PDI. This may be caused by moisture which has been trapped and condensed between the paint and the RAPGARD. These types of stains can be removed with a heat gun or an infrared drier. If you encounter this concern during PDI, use a heat gun or an infrared drier to apply heat to the affected area to remove the stain(s).
09-020-18-34582018-05-14. Service bulletin. EQUIPMENT:ELECTRICAL. Some vehicles may exhibit BLUETOOTH® hands-free and/or text messaging related concerns. To improve the handling of BLUETOOTH® hands-free and/or text messaging customer concerns, Mazda created a special service and parts exchange program as of February 2010. Customers experiencing related concerns should have their vehicle and/or device inspected according to the following procedure.
08-001-18-34572018-05-14. Service bulletin. AIR BAGS. This information is provided to help address Passenger Airbag Deactivation (PAD) Indicator illumination concerns during vehicle service.
07-002-18-34322018-05-14. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/Cevaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. "Mazda Air Cooling Coil Coating" is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers. This treatment provides a durable coating that will aid to prevent biological reactions that lead to odorconcerns. It is applied to the evaporator in a misted form that is introduced by way of the cabin air filter, the re-circulate door, the blower motor resistor access, or the blower motor air intake. Proper application requires the evaporator surface to be: Relatively clean and free of leaves, dust build-up and debris. Thoroughly dried, and the product cured onto it after application. NOTE: Keep the cooling unit dry by leaving the blower fan ON (at least on low), even if the A/C is not being used. In low humidity (dry) conditions, keep the ventilation system in the "FRESH" mode all the time, or as much as possible. In high humidity conditions, or if the air has a lot of dust or pollen, keep the system in the "RECIRCULATION" mode. A few minutes before reaching a destination, turn the A/C OFF, but leave the blower fan ON. This stops the accumulation of condensation on the evaporator/cooling unit, and it helps dry the inside of the cooling unit. A/C odor is not unique to Mazda vehicles as it will occur in other makes and models. To minimize A/C odor, suggest the following to the customers.
05-001-18-34532018-05-14. Service bulletin. EQUIPMENT; POWER TRAIN. Always be sure to use the correct automatic transmission fluid when replacing ATF. Using the wrong ATF may cause shift quality complaints or may even damage the transmission. NOTE: ATF M-V (TYPE M5) IS NOT THE SAME FLUID AS MERCON®V OR MERCON®LV ATF. ATF M-V (TYPE M5) HAS A GREATER VISCOSITY THAN MERCON®V AND MERCON®LV ATF IN LOW TEMPERATURES. ATF M-V (TYPE M5) HAS A GREATER ANTI-JUDDER SPECIFICATION THAN MERCON®V AND MERCON®LV ATF. TRANSMISSION FLUID FLUSHING SHOULD ONLY BE PERFORMED WHEN INSTRUCTED BY THE WORKSHOP MANUAL OR ANY OTHER MAZDA PUBLICATION.
04-004-18-34682018-05-14. Service bulletin. SERVICE BRAKES. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging. If you encounter a customer complaint for any one of these symptoms, refer to the following information to understand why symptoms may occur, and to better assist the customer in resolving their specific brake concern.
04-003-18-34552018-05-14. Service bulletin. ENGINE AND ENGINE COOLING. Some customers may report a slight clunk/bang/buzz noise or jolt from the front of the vehicle. This concern will most likely occur during the vehicles first forward movement after starting the engine. This is a normal operating noise of the Anti-Lock Brake System (ABS). Do not attempt any repairs. If you encounter a customer complaint for this concern, explain that the noise comes from the ABS/TCS/DSC "Malfunction Detection Function" initial check and that there is no problem. This initial check is a necessary function to ensure the normal operation of the ABS/TCS/DSC system. It occurs when the vehicles first moves forward under the following conditions. NOTE: Some customers may describe that the noise does not occur all the time. It does occur all the time, but the sound is more likely to be heard on a slow start and not on a quick start (quick acceleration) when engine noise is louder.
02-008-18-34672018-05-14. Service bulletin. WHEELS. Some automotive cleaning products contain strong acid or alkali. When these types of cleaners are used to clean the wheels on Mazda vehicles, the chemicals contents penetrate the clear coating of the wheel surface and damage the paint under the clear coating. The damaged area has the appearance of dark stains.
01-011-18-34562018-05-14. Service bulletin. EQUIPMENT. The vehicles listed above are equipped with a push button start/stop ignition system. Unlike previous Mazdamodels, there is no key cylinder on the steering column. Therefore, the engine cannot be started with theauxiliary key if the room fuse is removed or if the transmitter battery is dead.NOTE: The auxiliary key can only be used to lock or unlock the doors. It cannot be used to start the engine. Two transmitters are placed in a vinyl bag and stored in the center console cup holder. Since the room fuse is not installed during vehicle assembly, a new procedure is required to start the engine. Refer to "Engine Start Procedure" below.
09-007-18-34222018-05-07. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM); ELECTRICAL SYSTEM:SOFTWARE.
