Parking Brake Input

If the parking brake is applied before the ignition switch is turned to "RUN," the Daytime Running Lamps Module will be canceled. This allows the operator to start the vehicle and keep the headlamps off, as long as the parking brake remains applied. This feature is intended for use during service. When the parking brake is released while the ignition switch is in '"RUN," the Daytime Running Lamps Module will be activated. This feature will function only when the parking brake is applied before the ignition switch is turned to "RUN". If the parking brake is applied after the ignition switch is turned to "RUN," the Daytime Running Lamps Module will not be affected.
