Registering Stored Data
The SC003 command is used before replacing or reprogramming the ECU. This allows some data to be stored in the scan tool to transfer the configuration of the old ECU to the new unit. Stored data: injector codes, EGR programmed values, vehicle options, idle speed correction.
The SC001 command is used after replacing or reprogramming the ECU. It allows you to write data (saved with command SC003) to the new computer.
If it is not possible to set the communication mode with the ECU to be replaced, data storage will not be possible. After replacing the ECU, configure it manually according to the configuration or parameters using the appropriate commands.
SC002: Enter injector codes. CF028: Air conditioning, CF030: Heating pads VP010: VIN entry.
The programming of the EGR valve is performed automatically when a new ECU is connected to the on-board network.
Note. New or reprogrammed ECU.
Procedure
Before replacing or reprogramming the ECU, select SC003 «Saving data in the computer memory».
If the following message is displayed on the screen: - the saved data file already exists, do you want to replace this data?»: (this file was created the last time the instrument saved data), select «YES».
After saving the data, replace or reprogram the ECU, then proceed to the next step.
After replacing or reprogramming the ECU: Select SC001 «Registering Stored Data».
Follow the instructions given on the instrument screen. After executing the command, turn off «ignition», wait for the immobilizer warning light to start flashing (few seconds) and turn on «ignition».
Enter the communication mode and clear the fault data from the memory.
