Horn System - Operation

OPERATION

The horn system operates on battery current received through the Totally Integrated Power Module (TIPM). A signal is received by the TIPM from the Cab Compartment Node (CCN) over the Controller Area Network (CAN) Bus when the horn switch is pressed, and the horn(s) sound(s). The horn system circuit is designed so that the system will remain operational, regardless of the ignition switch position.
