Check if your Mazda has a Recall


February 1, 2019

 

Attention:  Mazda General, Service and Parts Managers 

Subject: STOP SALE – Announcement of Safety Recall 3019A – 2016-2019 MX-5Transmission Control Module Software Concern

 

Mazda Motor Corporation has decided to conduct a Recall Campaign on certain MX-5 vehicles produced from April 20, 2015 through December 11, 2018.

 

Subject Vehicles:

Model Subject VIN range Subject build date range
2016-2019 MY MX-5 Only equipped with Automatic Transmission JM1 ND A*7* G0 100033 – 119894

H0 100017 – 125192

J0 200004 – 206212

K0 300011 – 304295

From April 20, 2015 through December 11, 2018

– Number of subject vehicles:

Country Subject vehicles
USA 14,316

 

Action Required:

Beginning today, all unsold MX-5 (ND) vehicles equipped with an automatic transmission must not be delivered to customers until the recall repair is completed. There are approximately 760 unsold affected vehicles.

The repair procedure will be posted in MGSS under 3019A on February 1, 2019.  Please use MGSS to pull your affected vehicle list.  eMDCS should display this recall on February 1, 2019. Any affected vehicle will display 3019A in “Not Launched” status. “Not Launched” means that customer notification has not gone out, but the repair can still be performed and the recall closed. Once the repair is completed, the vehicle can be delivered.

 

Concern Outline:

In affected vehicles equipped with automatic transmissions, electrical noise in the range signal may be detected while driving in “D” range (including “Manual” mode). Due to inappropriate control logic of the clutch control software in the Transmission Control Module (TCM), this signal noise may cause the vehicle to unexpectedly downshift, causing an abrupt deceleration of the drive wheels.

A sudden decrease in the speed of the drive wheels while driving may negatively affect the directional stability of the vehicle, increasing the risk of losing vehicle control and potentially resulting in a crash. No crashes or injuries related to the subject condition have been reported to date.

 

Owner Notification:

Mazda will notify owners of affected vehicles by first class mail beginning in February 2019.  Owners will be asked to bring their vehicle to the nearest Mazda dealership to reprogram the TCM with modified software with MMDS.

Important Safety Notice: The National Traffic and Motor Vehicle Safety Act prohibits the delivery of any subject vehicle without performing the necessary repair for defects or failures. Failure to perform applicable recalls before delivery can result in extensive dealer fines and penalties from the Federal Government. Therefore, you must complete this recall for all affected vehicles in your inventory prior to delivery.

 

To help you effectively perform this recall, Mazda has developed the following resources:

  1. Warranty information, Repair procedures and Owner Letter will post on MGSS (Mazda Global Service Support) websites via MXConnect by February 1, 2019.
  2. Warranty information is also available on eMDCS.
  3. For technical assistance, contact the Technical Assistance Hotline at (888) 8328477, Option 3.
  4. For warranty questions, contact the Warranty Hotline at (877) 727-6626, Option 3.

Please make certain the appropriate personnel in your dealership are aware of these resources and are familiar with the details of this recall before responding to customer inquiries.

 

We  apologize  for  any  inconvenience  this  recall  may  cause  you  and  your  customers.  Your understanding and support in carrying out this campaign is greatly appreciated.

B.REPAIR PROCEDURE: TCM REPROGRAM

ACTION TO BE TAKEN

NOTE: The parameter “Battery State of Charge (SOC)” is reset during TCM reprogramming procedure.

  1. Reprogram the TCM with the Mazda Modular Diagnostic System (M-MDS) using IDS 112.04 or later software.

 

NOTE:

  • Verify the current TCM file name in the vehicle by log view screen. If it is the same as that in the below chart or later one, you do not need to reprogram it.
  • Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for TCM reprogramming.
  • Follow the attached “Service Caution for reprogramming”.
  • After the reprogramming, verify the calibration file name if it matches with in the below chart.

 

  1. Verify the repair by starting the engine and making sure there is no MIL illumination or abnormal warning lights present.

 

NOTE:

  • If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the Workshop Manual.

 

Calibration files information 

NOTE:

  • If the calibration file is with the suffix in the table or later, the TCM already has the modified calibration.
  • Older file name column shows the first four letters of the older file name only if some of the older file names are different from the new file name.

 

=== US spec. ===

MY TCM File Name
2016-2018 Convertible Top PEFB-18ZB3-E
2017-2018 Retractable Fastback PSPD-18ZB3-A
2019 PAC6-18ZB3-C

 

=== Mexico ===

MY TCM File Name
2017-2018 PSN1-18ZB3-B
2019 PAC6-18ZB3-C

 

Service Caution for Reprogramming 

NOTE:  Poor connection between the vehicle and M-MDS and/or low voltage may result in abnormal termination and/or data corruption.

a. Make sure that the following connections are firmly connected, and then do NOT touch the VCM and DLC cable to prevent from causing noise and poor connection.

  • Between the vehicle-side connector and the DLC cable
  • Between the PC-side connector and USB port of PC

 

b. Connect AC adapter to the PC in order to stabilize voltage fluctuation during reprogramming Do NOT use vehicle battery outlet as power source for the PC.

 

c. During reprogramming, connect battery charger (charge current maintained within 10 to 15A) to the vehicle to stabilize voltage fluctuation.

 

Before reprogramming, pay attention to the vehicle condition and PC environment.

a. Turn off all the electrical loads, especially pay attention to A/C (blower), audio, rear defogger and headlights.

b. Perform self-test and verify no DTC is stored. If any DTC is stored, fix the concern and delete the DTC.

c. Disconnect all non-genuine aftermarket accessories.

d. Terminate all programs other than IDS on the PC. This may extend reprogramming, PC may freeze or it may cause other problems.

e. Verify that the latest IDS software is installed on the PC.

f. Perform reprogramming under proper Internet environment. Especially when using wireless network, make sure the connection is strong.

g. Make sure to keep proper free space on the PC’s hard disc. Insufficient free space (less than 1 GB) may result in PC freeze during reprogramming.

MDSFA/MMP Required Hardware (Not Included)  

As shown in the diagram, an SAE J2534 pass-thru device is required to use the application.

J2534 Connection

 

Hardware validated by Mazda can be purchased separately from a third-party supplier. Validation has been done using the following J2534 pass-thru device and cables:

  • CarDAQ+ (includes RS232 and Ethernet cables)
  • Cable between CarDAQ and Vehicle – CD2534-J1962-FEPS (Sold separately / Required)

 

Important Information: Mazda makes no representations about the performance of third-party passthru devices. This pass-thru device list is provided voluntarily and as a courtesy. While our software meets SAE J2534, the pass-thru device manufacturer is responsible for making sure their pass-thru device operates properly on each Mazda vehicle and with Mazda software. We have listed the devices below because their manufacturers have attested that the tools have been validated to work. From time to time, we may test these devices. If we determine they do not operate properly or are obsolete, we may remove them from the list, without notice. Additionally, pass-thru devices listed here have been listed for their use with Mazda North American products only. While they may work with some European and other vehicles, they may not meet the requirements for those regions or operate properly.

 

Hardware can be purchased from a third-party supplier. Mazda has validated the following J2534 passthru devices:

 

**J2534 Pass-thru Device Manufacturer
*CarDAQ+ Drew Technologies Inc.
*Pass-Thru+XS Actia Corp.
*Snap-On Pass Thru Pro II Snap-On.
*Universal Reprogrammer EASE Diagnostics
*FLASH2 All-Makes Reprogrammer CARDONE Industries
*Bosch Mastertech VCI Bosch Diagnostics

*Contact the device manufacturer for the latest DLL and firmware versions.

**Many J2534 manufacturers sell and market similar J2534 devices with like names. Please exercise caution when using the list above for purposes of understanding devices Mazda has validated for use. J2534 Pass-thru Device Suppliers: Mazda has validated the J2534 devices listed on this page. Mazda does not plan to validate additional J2534 devices at this time.
