A specific button, such as Clear Virgin can lead your MediaNav device into a problem. Commonly, you will see a system not configured message on the screen. So, what do you have to do to fix this issue? According to lisandru.eu, there are two solutions you can do to fix connect diag tool error in MediaNav.

Fix It Using DDT4ALL

The first thing to do is to connect the ELM adapter to the OBD connector of the car as CAN2. Pin6 ELM, pin14 ELM, pin4, pin5, and pin16 are several wires you can use in this process. Now, launch the DDT4ALL and check the ECU.

You will see four different ECUs, which are ulc_gen1, ulc_gen2, ulc_gen3, and ulc_gen4. For this problem, you have to use the ECU name->ULC_gen4_v.1.4 setting. This action will launch the ECU configuration. Continue the process by clicking the write all and reset hard option. It triggers the GU system to reboot.

Go to DDT4LL and fill in the tuning parameters. Click the write all and resent hard again to launch the complete system configure message. In this step, the GU system will reboot. Wait for a few seconds until the pin code request appears.

Enter your pin code. The result depends on the adapter you use. Some low-end adapters can’t handle all data. As a result, you have to reconfigure some of them because the system doesn’t enter them yet.
