PCM REFLASHING
PCM Reprogramming Codes
A PCM Reflashing subscription allows you to program the Powertrain Control Modules on applicable Mazda
vehicles (sold in the United States and Canada) to the latest calibration level.
Note: For issues with MMP/MDSFA software, use the “Contact Us” submission at the bottom of the page.
The subscription includes access to download a software application that you can install on a PC.
For 2018 and later 6th generation models (2018 Mazda3, 2018-2019 CX-3. 2018-present Mazda6, MX-5, CX-5 and CX-9):
- Current MDFSFA Release = MDSFA 114.00, released 08/04/2019
- Update version = MDSFA 114.04
NOTE: For 7th generation models starting with 2019 Mazda3, MDSFA will not work for PCM reflash or key reprogramming. A M-MDS Software (MDARS) subscription will need to be purchased to reflash the PCM or key reprogramming using a Mazda VCM-II.
For 2017 and earlier models:
- Version MMP 114.00, released 08/03/2019
NOTE:
Calibration updates are for PCM (ECU) only. Medium speed CAN modules (BCM and other modules) cannot be reflashed using the MMP program and J2534 device. They must be programmed using IDS.
You may be required to access Technical Service Bulletins (TSBs) when programming a module. A Service Information subscription is not included, but can be purchased separately.
All 1996 models and later can be reflashed except for Miata. Only 2006 Miata (MX-5) and later can be reflashed.
