Take a photo of your connection.

[jvanski777]

I will upload photo soon. Everything was fine it started bypass and after that my internet connection was droped and it stoped bypassing and wrote failed. After that it is not connecting to mcu anymore and also I puted it back and puted back in car and there is no response from the srs module. No comunication

[AST_Support]

"Bypassing failed" can not damage the SRS unit.
You should check all your soldering for short circuits.

[jvanski777]

everything done perfectly but I have one problem. after mcu clearing crash I have to clear crash from external eeprom but it gives me this error code

[AST_Support]

Did you unsolder the EEPROM and insert it into the SmartProg adapter?

[jvanski777]

Yes I did and it gives me same error.

[AST_Support]

Take a photo of the EEPROM in the SmartProg adapter.

[jvanski777]

I can't post anything and I'm replying here. I was clearing crush from 89170-42280 srs module and car battery failed and writing flash failed and it is not comunicating anymore. what can I do?

[AST_Support]

You should create a new topic for a new problem.
You need to write 89170-42280.h8sx file using CPT H8SX UART connection.

[jvanski777]

please where I can find this file and how to connect by car pro tool if you can tell me? also I can't create new topic , it doesnot give me option

The cpt module wrote me it is not activated or expired. I bought this module why not activated?
