Buses with Automated Pre-Trip Exterior Light Check Feature
This feature allows operation of all exterior lights to be checked by the sole operator.
By use of a switch in the driver's area the operator can activate the exterior lights in
a flashing sequence based on related groups. The lights will flash on and off in the
sequence for five minutes and deactivate automatically. The system allows check of
lights only and does not verify switch or input circuit operation. To verify switch and
individual circuit operation, deactivate the Exterior Light Check feature and use the
exterior light switches for circuit and switch verification.
To activate the feature, apply the park brake, place the transmission shift lever in
park or neutral, and start the engine. To start the flash sequence press the switch la-
beled "EXT LGT CHECK" located in the right console switch panel. Releasing the park
brake, placing the bus in gear or switching the engine off will deactivate the system.
If the bus is equipped with sleeping child check feature, the system may be
armed by activating the Pre-Trip Exterior Light Check feature. An LED on the Doran
monitor will indicate if the sleeping child check feature has been armed.
