If my device also tries to send that same message and it is different that the other device in the car sending that message, the receiving device will get confused and may throw a code. Think of it like this, two people talking to a third person in a room telling them if he should ask a girl out. One is saying "YES" over and over while the other one is saying "NO" over and over. What's the guy to do!?
