  Summary

  This SA supersedes the previously issued SA(s) listed below. The changes are noted in Red. SA-061/25 12/17/25 DESCRIPTION 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 MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.

  Summary

  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.

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.

  Summary

  This Service Alert supersedes the previously issued SA(s) and TSB(s) listed below: The changes are noted in Red. SA-035/24 05/31/24 DESCRIPTION There is a concern that some water pumps are being replaced that are not faulty, due to signs of a very small coolant leak from the bleed hole. This Service Alert is to inform you about the water pump sealing mechanism and the criteria if replacement is necessary or not. A mechanical seal (A) is used for the water pump. This mechanical seal can seal coolant (B) by sliding a mating ring (C) against a seal ring (D). When the sliding surface temperature of the mechanical seal is more than 248 °F (120 °C) while driving, a small amount of steam (E) is leaked and bleeds through the bleeding hole (F). After drying, the steam leaves a green coolant deposit near the water pump bleed hole (F). This is a normal condition and does not require water pump replacement. The water pump should only be replaced if there is an accumulation of crystallized coolant near the bleed hole. When you encounter a water pump with coolant seepage marks, decide to replace it or not based on the following criteria using sample photos. NOTE: During the initial period of use*, the sliding surfaces of the seals may not yet be fully settled, which can temporarily increase the amount of leakage. Continued use will allow the surfaces to settle, reducing the leakage. Replacing parts that are already settled with new ones will increase the leakage again until the new parts become conditioned. Therefore, replacement should be avoided in this initial period of use. *As a guideline, this applies to vehicles with less than 1,860 miles (3000 km) of mileage.

  Summary

  Some customers may experience a check engine light ON with DTC P0126:00 (Thermostat stuck open) and one or more of the following symptoms: Engine takes longer to warm up. Engine temperature gauge fluctuates. Low coolant temperature indicator (blue) light stays on longer or turns on while driving. Poor heater performance, especially at idle. Vehicles with SKYACTIV-G 2.5T are not applicable to this service information. DTC P0126:00 is not required to be present to perform this repair. If the vehicle has not previously had the repair specified in this TSB and is exhibiting any of the listed symptoms, proceed with the repair procedure outlined in this bulletin. If DTC P2B61:00 (Coolant Control Valve Circuit Range/Performance) is present along with DTC P0126:00, this TSB does not apply. Diagnose the symptom and/or stored DTCs according to the procedures in MGSS. If only DTC P0126:00 is present and this TSB has already been completed previously, this bulletin does not apply, diagnose the symptom and/or stored DTCs according to the procedures in MGSS. This concern may be caused if the coolant control valve fail-safe thermostat opens at a temperature lower than the normal temperature due to a deformation of the thermostat diaphragm. To eliminate the concern, the water flow control valve specification has been modified. Affected vehicles will require PCM reprogramming with the Mazda Modular Diagnostic System (M-MDS), using either a) Mazda Diagnostic and Repair Software (MDARS) or b) Mazda Integrated Diagnostic System (IDS) 140.04 or later software.

  Summary

  The coolant control valve updated part is now available and supersedes PYFD-15-16ZA. As a result, PYFD-15-16ZA is no longer available. PW5S-15-16Z is supplied with a dummy plug pre-installed. Critical Installation Requirement: When replacing PW5S-15-16Z, the Powertrain Control Module (PCM) must also be updated to the latest software version. Failure to perform the PCM update may result in drivability concerns or diagnostic trouble codes.

  Summary

  SSPD8 - Check Engine Light ON with DTC P0126:00 - WARRANTY EXTENSION For certain 2018-2025MY CX-5, 2019-2023MY Mazda3, 2019-2022MY CX-3, 2018-2021MY Mazda6, 2020-2023MY CX-30 that are equipped with the suspected coolant control valve, the warranty coverage for specific repair of the fail-safe thermostat is extended to: 15 years (180 months) or 150,000 miles (240,000 km) whichever comes first, from the original warranty start date. CONDITION OF CONCERN: On certain subject vehicles, the check engine light is illuminated with DTC P0126:00 (Thermostat stuck open) stored in memory and one or more of the following symptoms may occur: - Engine takes longer to warm up. - Engine temperature gauge fluctuates. - Low coolant temperature indicator (blue) light stays on longer or turns on while driving. - Poor heater performance, especially at idle. Mazda Motor Corporation has made a significant repair change to TSB 01-003/25 which also impacts Warranty Extension Special Service Program (SSPD8). Repair Procedure Update: Effective December 8th all repairs applicable to TSB 01-003/25 or SSPD8 must follow the new repair procedure. The repair now replaces the thermostat with a dummy plug for the coolant control valve (CCV) along with a required software update for the PCM. Prior Repairs: Any repairs previously completed with the replacement of the thermostat or coolant control valve assembly does not require a re-repair unless there is a verified failure following the diagnosis in the TSB. It is expected that there will be no further repairs made for this concern once the plug and software update has been completed. Therefore, a return visit for symptoms related to the TSB or SSP must contact the Technical Hotline for assistance. VITALLY IMPORTANT!: There must be a “Software Update” record for the PCM when using MDARS or IDS. • MDARS - If there is no Software Update entry in MDARS or the Collect Diagnostic Information (ODR Update) is not completed (or both), the vehicle will not be considered repaired and the warranty claim will be rejected. • IDS – Vehicles programed with IDS must Collect Diagnostic Data, and that data must be attached to the warranty claim. If the data is not attached to the claim, the vehicle will not be considered repaired and the warranty claim will be rejected, denied or debited. Failure to complete the above will require the vehicle to return to the dealership and be re-repaired at the dealer’s expense with great inconvenience to the Mazda customer. Failure to perform the software update could also potentially damage the engine which would not be covered by warranty and would expose your dealership to the cost of repairs.
