This is not a common problem. It's been my experience that the most likely failure is the ECM, PCM or transmission control module. There are at least two CAN bus locations in a vehicle. They could be under the carpet, behind the kick panels, under the driver's seat, under the dash or between the A/C housing and center console. They handle communications for all the modules. A communications failure between anything in the network will cause this code. If additional codes are present to isolate the problem, diagnosis is simplified. The installation of performance enhancing computer chips or devices may not be compatible with the ECM or CAN bus wiring causing the lost communications code. A bent or pushed out pin terminal in one of the connectors or a loose ground to the computer will cause such a code. Jumping a dead battery and inadvertently reversing the polarity momentarily will destroy the computer.
