This concern may be caused by an internal failure of the PCM (DENSO produced only). To correct the concern, the PCM internal failure has been eliminated.

Customers having this concern should have their vehicle repaired using the following repair procedure.

 

REPAIR PROCEDURE

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.
