If your Cartrend Monitor isn't displaying anything, try these steps: First, start the engine. Make sure the head-up display is switched on. Check that the OBD connecting cable is correctly and firmly connected. If it still doesn't work, test the display in another vehicle. Finally, have your vehicle’s data link connector (DLC) checked.
