How to remove BMW Airbag 240 "Internal error" with Xprog

On the example of the control unit Temic 6577-6900727, he himself MRSZ3 V. 2.5-V. 3.0.  I will show you how to remove 240 "Internal error" error. This airbag has been installed in BMW e39, е38 and е46. 

For this you need a xprog box programmer that will be able to read the data from this ECU. We just need to record new memory without errors in the Motorola MC68HC12b32 element.

See the connection point below in the picture. Next, we take a clean memory, without errors, and save it using the xprog-m programmer in the Motorola element. Next, we set the control unit back to the car and we enjoy the capable system of safety again.
