How to Fix OBD2 Pairing Problem Solution 

Please check your OBDII 2 unit it could have a loose pin or component that connects when you applied pressure. If the connector from your car is faulty then all connectors will have the same issue but you said that your scanner works fine.

Same problem.

1.check if your head unit (radio) is connecting to your phone or other devices this might reject the OBD2 connection as some units can only chain connect to 1 device at a time. 2.check if your OBD2 is not losing power source or overpowered which reset its settings ( in times during engine start system power fluctuates to zero). 3. Test your OBD2 to another head unit and car if your observation is the same your OBD2 might be defective.
