Read 93C86 eeprom with vvdi prog, better solder following the wiring diagram.
Xhorse EEPROM clip will read but when loading to VVDI2 will say wrong file version.   Much better to desolder chip.

The module is a Siemens so you read the 93C86. If it is a Continental then you solder the wires on the back. Read out of circuit, you don’t want to corrupt the data. The chip is a 46 chip. You can clone out using a xhorse super chip xt27, write a file back using a 7936 or read the file and load into VVDI2 to program OBD.
