August 4, 2023 NHTSA CAMPAIGN NUMBER: 23V553000

Inaccurate Pedestrian Warning Sounds/FMVSS 141

Inaccurate external warning sounds may confuse pedestrians about the direction of an approaching vehicle, increasing the risk of a crash or injury.

 

NHTSA Campaign Number: 23V553

Manufacturer Mazda North American Operations

Components FORWARD COLLISION AVOIDANCE, BACK OVER PREVENTION

Potential Number of Units Affected 17,600

 

Summary

Mazda North American Operations (Mazda) is recalling certain 2024 CX-90 vehicles. Software in the Approaching Vehicle Audible System (AVAS) Information Sound Box (ISB) amplifier may be missing, which can cause inaccurate, external pedestrian warning sounds. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 141, “Minimum Sound Requirements for Hybrid Electric Vehicles.”

 

Remedy

Dealers will update the AVAS ISB amplifier software, free of charge. Owner notification letters are expected to be mailed October 3, 2023. Owners may contact Mazda customer service at 1-800-222-5500 Option 6. Mazda’s number for this recall is 6123H.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

CONDITION OF CONCERN

The pedestrian alert system has a warning sound for driving in reverse but may be activated in any gear other than “reverse”, due to missing software in the Approaching Vehicle Audible System Information Sound Box (AVAS ISB) amplifier. This concern may occur when the vehicle gear selector lever is moved through the various gears relatively quickly. The AVAS alerts pedestrians in the vicinity of the vehicle of its presence by generating an approaching vehicle alert sound while the vehicle is driven at a low speed. An improper AVAS warning can affect perception of vehicle directional movement and may increase the risk of an accident or injury.

REPAIR OUTLINE: Dealers will reprogram software of the AVAS ISB amplifier using M-MDS.

 


Chronology :

April 24 to May 11, 2023: Mazda discovered two cases with the erroneous function of the Approaching Vehicle Audible System (“AVAS”), intended to comply with FMVSS 141. These cases had occurred on vehicles at Mazda’s assembly plant in Japan.

June 20, 2023: Mazda identified root cause of this concern. Certain software was not installed in the AVAS Information Sound Box (“ISB”) amplifier. This caused the warning sound for moving backward in the “reverse” position to activate, even though the vehicle may be in any other gear shift position. This concern may occur when the vehicle gear selector lever is moved from “park” to “drive” or “park” to “neutral” and from “drive” or “neutral” to “park” relatively quickly.

July 05, 2023: Mazda carried out the countermeasure for mass production. Software to properly control the warning sound activation was installed in the AVAS ISB amplifier.

July 31, 2023: Mazda confirmed the vehicle condition with this concern does not comply with FMVSS 141 and held a Quality Audit Committee meeting to review all available information to date. Mazda determined to conduct a proactive field action on certain MY2024 CX-90 vehicles.

To date, Mazda has not received any field information reports.

Mazda is not aware of any accidents or injuries as a result of this concern.

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.
