i pressed but nothing. i have 1 hour and 10 minute from when i make paymment. i have to wait more?

This part number "KKTS-57K30" R7F701330 is supported in ASTPro and requires 1 token to clear crash data.

[radu_stoica78]

ok i have AST Pro but i can find this part number

[radu_stoica78]

can i read as another part number?

[AST_Support]

Use part number KMV6-57K30.
You need to clear the MCU and then the EEPROM.

2025 Mazda CX-50 VA4057K30, processor R7F701330A and eep 95256, CONNECT TO MCU PROBLEM!!!!
I am getting a mcu fail. HELP PLEASE!
The instructions are not very clear. After removing the 6 small capacitors , do they all need to be connected together and soldered to the P8 wire? Also does the eprom need to be removed before reading the processor or afterwards? Thank you

[radu_stoica78]

If you use zoom you will see that only part of the capacitors are connected together (the ones with black wire), the minus of the capacitors and on the right side where you have those big capacitors after you remove them put another capacitor between 400 and 600 Nf. I used 470nf.It is not necessary to remove the eep. After you are done with the processor, go to the eep and reset it there too.

Thank you Radu for the advice, but still I had the mcu fail message.

[radu_stoica78]

Don't forget to use 14v source and minim 2 amp because when you connect you have some lose voltage and this is reason that you have error when you want to read
