COMPLIANCE WITH NEW YORK STATE GENERAL BUSINESS LAW §399‑CCCCC (CONNECTED VEHICLE SERVICE; DOMESTIC VIOLENCE VICTIMS) DESCRIPTION This Service Information is issued in accordance with New York State General Business Law §399CCCCC (Connected Vehicle Service; Domestic Violence Victims). This regulation is intended to protect victims of domestic violence by allowing them to request the termination of third-party access (including access by an alleged abuser) to connected vehicle services, such as vehicle location tracking and remote control functions. To support this requirement, this Service Information enables confirmation of whether a vehicle is subject to connected vehicle services by referring to the SUBJECT VIN & PRODUCTION DATE RANGE, and provides guidance on the procedure to terminate such services when a customer requests the removal of third-party access for an applicable vehicle. Effective July 1, 2026, if a customer requests action under this regulation, a CMU/CDC software update must be performed to enable appropriate control of connected vehicle service access. If no request is made by the customer, the CMU/CDC software update is not required. REPAIR PROCEDURE 1. Confirm that the customer has requested deactivation of connected services in accordance with New York State General Business Law related action. 2. Perform the CMU/CDC software update according to the procedures outlined in the appropriate TSB shown in the table below: |

| SA-034-26 | 2026-06-04. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. This service alert supersedes the previously issued service alert listed below. The changes are noted in Red text. SA-047/25 10/07/25 DESCRIPTION When the Telematics Control Unit (TCU) replacement is necessary due to a failure, use MDARS to activate the new TCU after replacement. Use the information in this service alert to initialize the new TCU until the procedure on MGSS is updated. CAUTION: DO NOT swap TCU with another vehicle as the TCU is VIN locked after activation. A TCU swap with another vehicle will disable Connected Services on both vehicles. • If TCU activation is not performed, connected vehicle functions will not operate. This will have a negative impact on the customer because they will need to return to the dealer for repairs. • If the Telematics Control Unit (TCU) replacement is necessary, check "Vehicle Communication Line Status Reference" status detail first. The TCU can only be replaced under the following "Status Detail" conditions: Open Completed (OK) ○ Closed Completed (OK) ○ ○ If the TCU is replaced under the following "Status Detail" conditions, the customer may not be able to enroll into the replacement TCU. Processing (NG) ○ Request Failed (NG) ○ Open Failed (NG) ○ Flag Setting Failed TCU Activation 1. Install the new TCU. |

Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers. SCHEDULED MAINTENANCE Refer to the applicable Workshop Manual or Owner's Manual for vehicle -specific manufacturer scheduled maintenance. Workshop Manual - Refer to section 00-00 SCHEDULED MAINTENANCE. Owner's Manual - Refer to section 8 Maintenance and Care. b. Note: Please refer to the information below outlining the services not included in Mazda's Factory Scheduled Maintenance: IMPORTANT: Recommending fluid flushes when not necessary can lead to customer confusion and dissatisfaction. Fluid flushing for preventive maintenance purposes is strongly discouraged, unless otherwise specified in a published procedure (Owner’s Manual, Workshop Manual, Technical Service Bulletin, etc.). |
| SA-027-26 | 2026-05-05. Service bulletin. ELECTRICAL SYSTEM. This SA supersedes the previously issued bulletin(s) listed below. The changes are noted below in Red. SA-007/25 10/22/25, 06/02/25 and 02/03/25 DESCRIPTION The Mazda DCA-8000 is required for all warranty battery testing. If the Mazda DCA-8000 is not used, incorrect battery testing may result in unnecessary battery replacement. Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code. NOTE: A Warranty Code is required for warranty claim submission Battery Identification (Mazda batteries have 2 rating types) 1. JIS (Japanese Industrial Standard): JIS codes are six-digit alpha-numeric markings (excluding i-STOP batteries e.g. Q-85, S-95) molded into the top of the battery to identify a battery by the capacity (amps), dimensions, and battery terminal type. Vehicles manufactured in Japan come from the factory with a JIS rated battery. NOTE: Replacement batteries may use a CCA rating. If so, use the CCA rating listed on the battery. 2. CCA (Cold Cranking Amps): CCA ratings are normally located on a sticker affixed to the top of the battery to indicate a battery’s Cold Cranking Amps. CCA rated batteries are supplied with domestically produced vehicles. NOTE: If an incorrect CCA rating is entered into the Mazda DCA-8000, it will result in a false result and invalid Warranty Code from the tester. This will also result in unnecessary replacement of batteries. TEST PROCEDURE 1. Connect the charger clamps to the appropriate battery posts. |
| SA-026-26 | 2026-05-05. Service bulletin. ENGINE. This Service Alert supersedes the previously issued M-Tip(s) listed below. The changes are noted in Red text. MT-002/19 09/30/19 and 12/19/19 DESCRIPTION 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. Clean the intake manifold internally to remove any debris from old engine before installing the new replacement engine assembly. If the intake manifold cannot be properly cleaned internally, replace it. |
| 09-011-26 | 2026-03-03. Service bulletin. EXTERIOR LIGHTING. This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 09-019/25 04/15/25 Some vehicles equipped with the Adaptive Front lighting System (AFS) may exhibit the exterior light warning light/exterior light warning indication on while driving or when the ignition is turned on and DTC B10A3:86 (Error signal received from swivel actuator (LH)) stored in memory. NOTE: The combination light with AFS can be distinguished if it is equipped with the parking light/daytime running light (DRL) that illuminates while the ignition is turned on. This may be caused by the AFS Control Module detecting a false headlight malfunction. This concern will likely occur when the light returns to the center position after swiveling. To eliminate this concern, the control software of the AFS control module has been further modified. |
| SA-005-26 | 2026-02-03. Service bulletin. UNKNOWN OR OTHER. There are currently 2 methods for cutting a new auxiliary key blank. A. Auxiliary Key Trace Cut Method • B. Auxiliary Key Code Cut Method 2019 and newer models require a 10-digit key code to accurately cut keys • 5-digit codes CANNOT be provided for 2019 and newer vehicles (the traditional 5-digit code from the key tag or driver's door lock cylinder is not sufficient and will not be issued for key cutting on these models). • Only Mazda-approved key cutting machines can process these 10-digit codes. • Many older key machines do not support 10-digit codes and cannot be updated to do so. In these cases, dealers will need to purchase one of the newer Mazda-approved key cutting machines capable of handling this requirement. • For a list of current Mazda-approved machines and purchasing options, refer to the Mazda Dealer Equipment Program or view the current Mazda approved key machines below. |
The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
