Abstract
A receiver is presented herein for use in a keyless vehicle entry system for controlling a vehicle device function, such as unlocking a vehicle door, in response to a vehicle function request signal received from a portable transmitter. The receiver includes a controller having a normal mode of operation during which it receives a request signal and determines whether the request signal is valid and, if so, it initiates the vehicle device function. The controller has a diagnostic mode of operation during which it initiates the vehicle device function in response to receiving a request signal without determining whether the request signal is valid. Provision is made for switching between the modes of operation.
