Patent Images
1. A vehicle comprising:
- communication nodes including a first node and a second node, the first node to send a first of test signals to and receive a second of the test signals from the second node, the communication nodes include an exterior node configured to wirelessly communicate with a mobile device to initiate passive entry into a vehicle cabin; and
a controller to;
determine signal strengths of the test signals; and
at least partially disable passive entry passive start responsive to determining one or more of the communication nodes is impaired based upon the signal strengths.

Abstract
Method and apparatus are disclosed for status tests of wireless communication nodes of vehicles. An example vehicle includes communication nodes including a first node and a second node. The first node is to send a first of test signals to and receive a second of the test signals from the second node. The example vehicle also includes a controller to determine signal strengths of the test signals and at least partially disable passive entry passive start responsive to determining one or more of the communication nodes is impaired based upon the signal strengths.
