Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Update MAZDA CONNECT with software version 7000C0A-NA01_11012 or later using the 7TH GEN MAZDA
CONNECT Update Instructions on MGSS.
CAUTION: More than one software version can be placed on a memory stick, but Mazda recommends placing only one
version on a memory stick to avoid updating the system with the wrong version.
3. [For 2019 Mazda3 only (Additional repair procedure)]: When the CMU is updated from older version than 7000C0ANA01_10040, the TCU and the BCM need to be reprogrammed together to have the vehicle be ready for activation of the
connected service. If they are not reprogrammed, communication error between CMU occurs.
a. Reprogram the TCU and the BCM with the Mazda Modular Diagnostic System (M-MDS), using Mazda
Diagnostic And Repair Software (MDARS) and claim the labor hours according to the warranty information shown
below.
• After CMU update, an additional button appears at the right bottom corner of the screen. This means that the
communication unit is unsubscribed or a Connected Service contract has been ended.
• After CMU update, “Wi-Fi Settings” is added to the Connectivity Settings but it is grayed out and not active.
• If current calibration file name in the ECU FILENAME screen is same as shown below or with later suffix,
reprogramming is not necessary.
• [5HB] If the vehicle is applicable to the Mazda Service Program MSP56, performing the MSP56 repair procedure
updates BCM (and LFU) to the modified version.
