15-003-20-3737a2020-11-03. Service bulletin. STEERING; FORWARD COLLISION AVOIDANCE; SERVICE BRAKES; ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Some vehicles may exhibit that the SBS/SCBS warning light (amber) turns ON right after the engine is started with DTC U0420:68 [FSC] (Error signal received from electric power steering (EPS) control module) stored in memory. For Mazda6 and CX-5, the following error messages may appear in the instrument cluster. • Front camera sensor system malfunction • Forward Smart City Brake Support Malfunction • Driver attention alert system malfunction. This may be caused by the battery voltage falling and the EPS control module failing the initial learning for the steering center position while cranking. The FSC detects the error notified by the EPS control module. To correct this concern, the control software of the EPS control module has been modified while the repair procedure modifies the FSC for earlier repairs in the market.

SA-063-202020-09-03. Service bulletin. ELECTRICAL SYSTEM. When performing vehicle services such as control unit software update, control unit registration/activation, CMU log data retrieval, etc., always use the GR8 battery charger SST to maintain battery voltage.
MT-001-202020-08-04. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. 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.
09-025-20-37212020-08-04. Service bulletin. VISIBILITY; ELECTRICAL SYSTEM. Some customer's may complain that the front power window(s) do not operate after the vehicle has been parked outside during freezing temperatures. This may be caused by water that infiltrates into the power window regulator and freezes in the drum groove for the cable. Then when the power window is operated, the cable slips out from the ice-filled groove and tangles, blocking further window operations.
09-015-20-3698b2020-07-02. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Some customers may experience the MAZDA CONNECT rebooting or the screen turning black during cold temperatures. The concern occurs when the interior of the vehicle is cold and disappears when the interior warms up. This is caused by some SD cards for the MAZDA CONNECT navigation system being manufactured with improper hardware, resulting in a data reading error during cold temperatures. To correct the concern, the SD card hardware has been changed.

SA-009-202020-01-30. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING; STRUCTURE. LACK OF POWER UNDER HEAVY LOAD WITH NO WARNING LIGHTS OR DTCS: Some customers may complain of a lack of power under heavy load without any warning lights or DTCs.

01-002-20-36782020-01-30. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Some vehicles may experience the CHECK ENGINE LIGHT ON with DTC P2610 and P2507 stored in memory 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.
09-003-20-36712020-01-23. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. 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 odometer and 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 “Speedometer Replacement 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, 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.

07-007-19-36382019-11-21. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; ENGINE. Some customers may complain about poor heater performance even after the engine reaches normal operating temperature. This may be caused by a plugged heater core. For 2014-2016 Mazda6 and 2013-2016 (US spec) / 2017 (Mexico spec) CX-5, the CHECK ENGINE light may turn on with DTC P011A:00 (ECT sensor No.1/No.2 performance problem) stored at the same time. NOTE: Refer to TSB 01-015/15 if the customer is using a block heater at temperatures below freezing. To solve this concern, two mass production changes have been implemented. a) The concentration of the coolant has been increased so that the amount of the contained anti-rust additive is higher. b) The composition of the coolant has been changed (the ratio of the anti-rust additive has increased).
