    Then clear the codes if they come back your sensors on the brake pads could be dirty? Give them a clean at the connections, if doesnt work replace! Same thing for the sensor to water bottle?!

    Radio is coded to car so as long as same unit goes into the car you shouldn't have to enter the code.
