  • SmartProg make P8 wire shorter

    I bought SmartProg a month ago. Yesterday I got module for Subaru 2023 #98221 FN22A (R7F701686). I connect by OBD and read codes. I tried to read MCU, shows me message "make P8 wire shorter". I shorter wire to 3 cm but it still showed the same message. What solution with this problem

    To test P8 in the SmartProg adapter, go to the main model selection window in AirbagCANServiceTool and measure the resistance between P8 and GND2 with a multimeter, it should be 0.
    Next, make a good GND2 connection. A better way is to solder a good wire from GND2 to the SRS or connect GND to SRS ECU connector as shown on the picture.
    Next, try to make a Y type P8 connection cable.

      Resistance between P8 and GND 14,26 kOm. On picture, I not sure this is transistor or something else, but resistance between two marked pins is 85 Om. Is this normal?

        Connected SmartProg to SmartOBD and run AirbagCANServiceTool?

          When I connect and run AirbagCANServiceTool, Voltage between P8 and GND is 1.25 V, it's impossible measure resistance

            1.25V appears when you press Read EEPROM button.
            Go to the main model selection window in AirbagCANServiceTool and measure the resistance between P8 and GND2.

              When I press Read it decreases from 1.25v to 0.68v. Resistance is 20 MOm if I change the polarity it shows zero. But it not resistance.

                Ok, try to disconnect the USB from SmartOBD and measuring the resistance between P8 and GND immediately after connecting. You can even close AirbagCANSrviceTool.
                Take a picture of the SmartOBD pcb.
