If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal Workshop Manual diagnosis. Aftermarket devices may be the cause of the electrical concern. Ask the customer if any aftermarket devices have been installed. Below are a couple of examples of unusual electrical concerns caused by aftermarket devices.

Some vehicles equipped with Smart Brake Support (SBS) may exhibit a front radar system malfunction message in the instrument cluster with DTC C1A67:04 (front radar sensor internal malfunction) stored in memory. This may be caused by water penetrating into the front radar sensor through the breather hole and damaging the radar sensor, resulting in the DTC C1A67:04. To eliminate this concern, the front radar sensor has been modified.

Some customers may complain about a very low frequency noise and/or vibration felt at the steering wheel, the floor and/or the seats when driving at 1500-1650 rpm in any gear position. This may be caused by normal vehicle behavior while the cylinder deactivation is active (two cylinders drive). The state of the cylinder deactivation can be monitored in the center display to help verify if this is the issue. WARNING: DO NOT keep your eyes focused solely on the display while test driving. For your safety, keep your eyes on the road ahead. To correct this concern, the radiator mount brackets and the control software of the PCM have been modified to reduce the resonance of the radiator. NOTE: The combination of the modified radiator mount brackets and older PCM calibration may result in worse vibration.

Some vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability.

Some customers may experience that the door locks may not operate using the touch sensor on the outer door handle while parked in a parking space surrounded by concrete walls, but will operate when using the remote transmitter. This concern may be caused by refraction and/or diffraction of the signal used for the advanced keyless entry system by the steel reinforcement bars in the concrete walls. As a result, the signal will resemble a theft attempt (known as a Relay Attack) and the anti-theft function of the advanced keyless entry system will prohibit door lock operation. To eliminate this concern, the LF control unit software has been modified to reduce the improper detection of the theft attempt.

Some customers may complain that their seat warmers or seat ventilation do not turn on when the engine is restarted after being left on when turning off the engine. The logic has changed from previous Mazdas where the seat warmers and seat ventilation automatically turned on when the engine was restarted. NOTE: Customers in cold weather are more likely to complain about this if their vehicle is equipped with Mazda Mobile Start (MMS) (not available on Mazda3 or CX-30) because the MMS accessory instructions state the seat warmers WILL turn on when the engine is restarted. The same can happen in the hotter weather with the seat ventilation. This information is incorrect for these vehicles. Both features will now require a manual setting every time the vehicles are restarted after being turned off. Consult the vehicleâÂÂs ownerâÂÂs manual for more details on proper seat warmer/seat ventilation operation.

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 dealerâÂÂs responsibility to comply with Federal, State, and local laws concerning odometer and related documentation requirements when providing a repair or replacement. ï· Mazda vehicles are manufactured with tamper-proof speedometers. ï· When a speedometer is replaced, the new speedometer will read zero (0) miles. ï· This procedure is extremely important to accurately represent actual vehicle mileage. ï· Prior to speedometer removal, complete the information required on the âÂÂSpeedometer Replacement LabelâÂÂ. Labels can only be ordered through Mazda eStore. ï· In an effort to achieve a higher level of Customer Experience and retain the value of MazdaâÂÂs 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 SPECMOâÂÂs services, it is possible that the odometer will be set between 10 to 31 miles over the odometer mileage at the time of replacement for both warranty and customer pay repairs. Please make sure that the customer is aware that there may be a slight variance to the odometer, in which case the customer may have to accept the slightly higher mileage. 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.

Some vehicles may exhibit corrosion of the wheel nuts. This is caused by torsional stress concentrating on the tip of the wheel nut because of the thin and long shape of the nut, which damages the coating and causes the corrosion. To correct this issue, the width across the flats of the wheel nuts have been changed from 17mm to 21mm.

If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage.

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/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. âÂÂMazda Air Cooling Coil Coatingâ 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.
