Park Brake Input

The DRL control module will not operate any headlamps or exterior lamps if the park brake is applied before the ignition switch is turned to PUN. This allows the operator to start the vehicle and keep the headlamps oft as long as the park brake is applied. The DRL control module will activate the headlamps when the park brake is released with the ignition switch in RUN.

The park brake input feature will only function when the park brake is applied before the ignition switch is turned to RUN. The headlamps will not turn off if the park brake is applied after the ignition switch is turned to RUN.
