Diagnostic system for a vehicle
First Claim
1. A vehicle comprising:
- a chassis;
a plurality of wheels connected to the chassis;
a vehicle control system comprising a plurality of controllers configured for controlling different components of the vehicle, a vehicle network connected to the controllers and configured to permit communication to and from the controllers, and a primary vehicle controller connected to the vehicle network and configured to communicate with the controllers; and
a vehicle diagnostic system comprising a memory, a processor, and a display, the vehicle diagnostic system connected to the vehicle network and configured to communicate with the controllers and the primary vehicle controller, wherein the vehicle diagnostic system is configured to operate in a diagnostic mode, in which the vehicle diagnostic system is configured to display diagnostic information from one or more of the controllers,wherein the vehicle diagnostic system is configured for transmitting a first signal to force a first output from the vehicle control system, and wherein a first controller of the plurality of controllers is configured to only accept instructions from the primary vehicle controller such that instructions from the vehicle diagnostic system to the first controller to force the first output are only communicated indirectly through the primary vehicle controller.

Abstract
A vehicle that includes a chassis, wheels, a drivetrain including an engine and a transmission, and a brake system. The vehicle also has a vehicle control system that includes controllers for the engine, the transmission controller, and the brake system, a vehicle network connected to the controllers to permit communication to and from these components, and a primary vehicle controller connected to the network and configured to communicate with the controllers. The vehicle further includes a vehicle diagnostic system that is connected to the network and configured to communicate with the various controllers. The diagnostic system is configured to operate in a diagnostic mode, in which the diagnostic system is configured to display diagnostic information from one or more of the controllers. The diagnostic system may further be configured to operate in a display mode, where the vehicle diagnostic system is configured to display operating information regarding the vehicle.
