[SLICK]

Hi

I have Toyota bz4x airbag ecu 89170-42e00, with R7F701684

When trying to remove crash by CAN its gives error, Get Seed ..... Failed

Does this mean we have to open ecu and use SmartProg?

This means that Clear Crash by OBD may not work.
You need to read the MCU using the SmartProg adapter.
Yes, problem with 1 picture. Use part number 89170-52U10 (by SmartProg).
