[keneli]

CAR BRAND NAME: volvo
MODEL: s60
PART NUMBER: p32387682
CPU / EEPROM r7f701330

Hello, have srs p32387682 and mvbm 32400883, car not ready/drive. Need algoritm clear crash srs, cpu after or before eprom, pls help.
Battery need opening , or by obd clearing? How many tokens need for all procedure?
Cem and vgm module i not have.

[AST_Support]

If the MVBM is discharged, you need to disassemble it, check all elements, and charge it to 48 V. Then assemble it and use the Clear Crash by OBD.
For the SRS unit you only need 1 token to write the MCU, all others will not use tokens.

[keneli]

Ok, thanks, write mcu and after write eprom or only mcu write?

[AST_Support]

The crash data is in both, so you need to write the data to the MCU and then to the EEPROM.
If the SRS unit was manufactured before 2024, you can try Clear Crash by OBD using the second picture.

i clear crash mvbm , but eror not clear.

hello, i buy token, want to flash it srs,I need to solder something?

[AST_Support]

What is the part number?

DC power supply voltage +12,19V
Turn on 12V on the adapter... ok
Connect... ok
Bosch diagnostics are locked, you need to read the MCU data directly.

[AST_Support]

You need to connect using the SmartProg adapter, read the MCU, use Clear Crash by dump and write the MCU.
