Honda Jazz 2011 - 77960-TF0-G832-M3

Hello,

Can someone help me please?

I have a problem with airbag module for Honda Jazz 2011 - 77960-TF0-G832-M3

There is a crashdata, but there's no eeprom or any other kind of memory I can read inside the module. There's only a CPU with mask: 0M26V. I'll attach a picture.

I'm searching for any kind of info or tips to read that module and clear the crashdata afterthat.

 

Any help is appriciated!

Thanks in advance

 

PS: Sorry that I'm writing in English, but my Russian is bad. You can answer me in Russian, I can understand, but it's hard to write on.

Actualy I found some info.

The CPU is MPC5604 and the crash data is inside the flash area. It's the new system between Bosch and Freescale for the newer Airbag modules. The cpu can be read trough JTAG iface and I got the pinouts. Tomorrow will try to read the module and will try to find a workaround. Will write back the results and will post a dump or so.

Here are some screenshots. Maybe someone will need them later.

Crashdata is stored in Data Flash (64k) after address 0x8000.

I'm sorry for writing in English, but it will be kinda bad to use Google Translate (English -> Russian). And of course I have a respect on you, but I can't write in Russian :(

If it's not allowed to write in English, please let me know.

Hello again.

I bought the programmer and have read my Data Flash (64k) in MPC5604. Can someone give me some tips how to clean up the crashdata inside? I know that the crash is stored after 0x8000, but I tried to FF some addresses after 8000 with no luck.

I attached my dump.
