Does your reader work on other cars? If it does, your OBDII port might me disconnected or missing one of the required pins.

    I have a 2004 Tahoe, the check engine came on and I was told it may be the bearing. Could that be? If so, does something else need to be repaired in addition/conjunction to the bearing? Thank you :)
