Vehicles with Detroit Diesel Optimized Idle

p3 dm 08.03.002

If a Cascadia vehicle is equipped with Detroit Diesel optimized idle (O/I), it will affect the way the ParkSmart operates. When the driver initiates the O/I, the ParkSmart will operate in O/I mode as follows.

  • The ParkSmart runs unless the ParkSmart fan speed control knob is turned to the "OFF" position. See Fig.. The fan speed control knob must be set at "1" or higher.

  • The engine will periodically start and run for at least two hours to maintain battery voltage then shut off. The ParkSmart will continue to operate during this time.

  • If the O/I shuts down due to a fault in the O/I system, the ParkSmart will continue to operate until it is shut off by the driver or one of the automated failsafes.

  • The ParkSmart ON/OFF button and LED indicator on the parked HVAC control module do not function when the vehicle is in O/I mode. When the vehicle is not in O/I mode, the ParkSmart ON/OFF button and LED indicator operate normally.
