Abstract

A method and device provides for the testing and validation of a control module for receiving wireless data and communications utilizes a transmission line coupler mounted proximate the control module generates a signal that couples to an antenna of the control module. The control module produces a signal in response to coupling of the antenna with the signal produced by the transmission line coupler. The resulting signal is utilized to check, verify and validate operation of the control module.

Claims

1. An electronic control module for a motor vehicle comprising:

a housing;

an antenna for receiving a wireless signal supported by the housing;

a test device mounted to an outer surface of the housing, wherein the test device generates an electromagnetic signal independent of the control module for coupling to the antenna supported within the housing.

2. The control module as recited in claim 8, wherein the test device comprises a transmission line coupler.

3. The control module as recited in claim 8, wherein the test device comprises a ground conductor disposed on a first side of a dielectric and a transmission conductor disposed on a second side of the dielectric.

4. The control module as recited in claim 10, wherein the test device comprises a connector for receiving a signal input.

5. The control module as recited in claim 8, wherein the control module is mountable to a motor vehicle support structure and the test device is mountable between the control module and the motor vehicle support structure.

6. The control module as recited in claim 8, wherein the test device generates an electromagnetic signal that is coupled to the antenna of the control module.

7. The control module as recited in claim 13, wherein the test device is driven by a controller external to the motor vehicle.
