Airbbag Fiat Ducato 2012
SRS TRW
no. 01370978080
eeprom 95640
B0100-49 - internal electronic failure - after battery voltage drop
When I cleaned it using the dump tool, it removed too much during the diagnosis because even the HW SW changed.
File repair request.
Attached is a photo and dump eeprom

[AST_Support]

It's tested solution, check EEPROM soldering.
Post screenshots of that HW and SW versions.

[marekch]

Eeprom read in the system without desoldering.

[AST_Support]

This is bad diagnostic. It's just read all fields. I don't think this is real HW and SW versions.

[AST_Support]

Internal Error is gone after writing cleared file?

[marekch]

Yes,
Attached is a screenshot after the file has been cleared by cleared dump

[AST_Support]

There is no part number, it's very bad. After you write original file everything is ok? Except internal.

[AST_Support]

I don't recommend to use clips for programming eeprom on pcb. Desolder EEPROM and write clear file.

[marekch]

This is much smaller TSSOP8 eeprom, not normal SMD on clips.
I always use DP4 to read the system and when it reads the eeprom, it verifies the reading and shows the same thing every time.
I read this eeprom several times and each time it is the same.

[AST_Support]

There is always a risk of damage to the processor pins. And after this no matter what you read or write to EEPROM, CPU will not read anything.
Write original data and check Part Number.
