3019A - Transmission Control Module Software Concern (3019A)

3019A - TRANSMISSION CONTROL MODULE SOFTWARE CONCERN

SERVICE CAMPAIGN BULLETIN

DESCRIPTION

In affected vehicles equipped with automatic transmissions, electrical noise may be detected while driving in "D" range (including "Manual" mode). Due to inappropriate control logic of the 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.

The sudden unexpected downshift while driving may negatively affect the stability of the vehicle, increasing the risk of losing vehicle control, potentially resulting in a crash. No crashes or injuries related to the subject condition have been reported to date.

This recall is in Not Launched Status, however vehicles can be repaired. Please make sure if a vehicle arrives at your dealership that the repair is completed.

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.

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 M-MDS.

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) 832-8477, 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.

   • Between the vehicle-side connector and the DLC cable
   • Between the PC-side connector and USB port of PC
2. 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.
3. 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. 

1. Turn off all the electrical loads, especially pay attention to A/C (blower), audio, rear defogger and headlights.
2. Perform self-test and verify no DTC is stored. If any DTC is stored, fix the concern and delete the DTC.
3. Disconnect all non-genuine aftermarket accessories.
4. Terminate all programs other than IDS on the PC. This may extend reprogramming, PC may freeze or it may cause other problems.
5. Verify that the latest IDS software is installed on the PC.
6. Perform reprogramming under proper Internet environment. Especially when using wireless network, make sure the connection is strong.
7. 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.
