STEP 1
Find SAK TC1797 EEPROM memory and unsolder it
STEP 2
Using a programmer, read the content of the ECUs EEPROM memory
Find the values in addresses from 8108-810D (marked in blue)
Read values: 07 | EA | DA | 74 | A4 | 99
ATTENTION: The picture shows example values.These values are different in every ECU.
STEP 3
Remove 24C02 memory from S.O.S Pro Emulator
STEP 4
Write these values onto the 24C02 memory unsoldered from s.o.s pro emulator.
STEP 5
Solder back the 24C02
Use tin to bridge leg 7 and 8 of the 24C02 memory
To choose the program you have to solder specific jumpers on the Emulator
STEP 6 Connect the S.O.S Pro Emulator to the ECU according to the diagram below.
Attention!
Disconnect antenna coil from ignition switch!
