Abstract
The present invention concerns a method for verifying a command in a vehicle remote communication system. The remote communication system includes a remote transmitter, and a vehicle body having a receiver module and a control module connected by a communication bus disposed therein. The control module is in communication with at least one vehicle system. The remote transmitter transmits an activation signal that is received and decoded by the receiver module. The receiver module transmits a first message along the communication bus that is received by the control module. The control module transmits an acknowledgment message that is received by the receiver module. The receiver module re-transmits the first message that is received by the control module. The control module then initializes a vehicle system command to the vehicle system, thereby preventing an inadvertent activation of the vehicle system.
