Vehicle Specific PIDs

The Vehicle Specific tab provides access to a built-in library of manufacturer-specific diagnostic parameters. These are PIDs that go beyond the standard OBD2 set, allowing you to monitor data points unique to your specific make and model (e.g., Tesla Battery Health, Nissan Leaf State of Charge, or BMW Transmission Temp).

The Configuration Process

Step 1: Access the Menu

1. Connect to the WiCAN Web Interface.
2. Navigate to Automate > Automate Parameters.
3. Select the Vehicle Specific tab.

Step 2: Selecting your Vehicle Library

Instead of scanning, you browse the internal WiCAN database:

1. Manufacturer: Select your car's brand from the dropdown menu.
2. Model/System: Select the specific model or subsystem (e.g., "Tesla Model 3 - Battery" or "VW ID.4 - Thermal Management").
3. Browse PIDs: A list of specialized parameters will appear in the Available PIDs dropdown.

Step 3: Adding Parameters

1. Choose a PID from the dropdown list.
2. Click the Add button.
3. The PID will appear in the configuration table below, pre-loaded with the correct headers and math formulas provided by the library.
4. Repeat for all manufacturer-specific data points you want to track.

Step 4: Fine-Tuning the Settings

For every added PID, you can adjust the following:

• Enable: Toggle the switch to start/stop polling.
• Interval (ms): Set the refresh rate. Manufacturer-specific ECUs can sometimes be slower than the main Engine ECU; an interval of 500ms to 2000ms is usually recommended for non-critical data.
• Destination: Route the data to a specific User Destination.
• Log to SD: Check this to save the specific data to your log files.

Step 5: Save and Apply

1. Scroll to the bottom and click Save Configuration.
2. The WiCAN Pro will begin requesting these specific memory addresses from the vehicle.

Integration with Vehicle Groups

Just like with Standard PIDs, you can easily move these settings into an organized group:

1. Go to the Vehicle Groups tab.
2. Select your target group.
3. Use the "Copy Vehicle Specific PIDs" button.
4. This pulls everything you just configured into that group, allowing for easy profile switching.

Why use Vehicle Specific PIDs?

Standard OBD2 PIDs are limited to about 40–100 items. Vehicle Specific PIDs unlock hundreds of additional data points:

!TIP If your vehicle is not listed in the library, don't worry! You can still add any parameter manually using the User Custom PIDs tab if you have the hex codes and formulas.
