Mazda 2020 with S6J329

[junmab]

Hi all,

Does any one know how to read the data-flash of this MCU for the km ?

Remove needel order side have eeprom or your tool make obd2

Mate, Your suggestion will work on 2019 model.
This is the first Mazda3 equipped with VISTEON cluster i see, and i saw a lot of them.
This one has no EEPROM.
Attached is a picture from the other side of PCB.
I assume it is different from the S6J3001 that DENSO uses in Toyota's clusters(RAV4 2019,Corolla 2020).
BTW, the needles does not have to be removed in this cluster to reach both sides of the PCB.

Thanks anyway, and hope there will be a solution for this S6J329 mcu. Soon

Do u have cg100 the programmer haves the connection

There is no mileage there.

Is there a solution for this Mazda3 ?

[Steve182]

No solution yet, and the km are not in the dash…
Some months ago I pulled out the dash of a Mazda to try to modify km (without succes), and the customer drive the car 1day without the dash, the surprise when I install back the dash it adds the kms that drive without the dash…

It was synchronization with other ecu blocks only

This shity problem is in Mazda3 and Mazda CX30 from 2020.
I replaced a cluster from scrap and it showed the same km as the car has, so probably the km is not in the dash.
Does any one knows where the km is stored in these cars ?

Thank you very much daotuenghi for this very useful information.
Please let me know if you had a success reading this MCU and with what tool, if you please.

Thanks for your reply.
1) What is the reason you add the diagram of the DSC module ?
2) If you can not process the km in the BCM, then how can you be sure that the km is in this BCM ?
3) Could you kindly upload here the file you read from the R7F7010033 ?

[daotuenghi]

I replace 1 bcm of another car, the number of kilometers changes accordingly

I have a Mazda3 at my workshop, but i can not locate this box as in the picture.
Can some one advise what is the location of this BCM BCKA 67560 ?
