Aftermarket module arrangement and method for communicating over a vehicle bus
First Claim
1. An aftermarket module arrangement for installation into a vehicle having a vehicle bus and an electric power source, the aftermarket module arrangement comprising:
- a module configured to communicatively couple with the vehicle bus and to electrically couple with the electric power source via a first electric power line, the module further configured to engage in power line communications over the first electric power line; and
an aftermarket module configured to electrically couple with the electric power source over a second electric power line and to engage in power line communications over the second electric power line,wherein the aftermarket module is further configured to communicatively couple with the module via power line communications and to communicate over the vehicle bus through the module when the module is communicatively coupled with the vehicle bus and when the aftermarket module is communicatively coupled with the module, and wherein the aftermarket module is powered by the electric power source without intervention by the module.
