ABS ON-OFF code diagnostics communication system
First Claim
1. An antilock brake system diagnostics communication system for a vehicle having an antilock brake system, comprising:
- a user interface capable of generating a user request signal;
an electronic control unit capable of receiving the user request signal and generating ON-OFF code data indicative of a diagnostic condition of the antilock brake system in response to the user request signal; and
an output device capable of communicating the ON-OFF code data from the electronic control unit to a user located within the vehicle.

Abstract
A trailer ABS diagnostics display system utilizes an output device to communicate specific ABS diagnostics information to a user located within the tractor cab in the form of ON-OFF code data. The system preferably includes wheel velocity sensors, at least one brake pressure modulator, an output device, a user interface which generates a user request signal, and an electronic control unit that is connected to the wheel velocity sensors, the brake pressure modulator, the output device, and the user interface. The electronic control unit generates the ON-OFF code data which is indicative of a diagnostic condition in response to the user request signal. The ON-OFF code data is transmitted to the output device for communication to the user located with the tractor cab.
