Slide 1:The SECURITY Telltale on the message centre is controlled by the Vehicle Theft Deterrent (VTD) system. The SECURITY telltale is a part of the reconfigurable message centre on the instrument cluster. The SECURITY telltale is controlled by the body control module through the class 2 data line. The SECURITY telltale appears on the message centre inside the instrument cluster. If the SECURITY telltale flashes or if the SECURITY telltale lights continuously during the vehicle operation, there is a problem and the vehicle may or may not start and run. The SECURITY Telltale will illuminate if the vehicle is attempted to be started without using the right key SECURITY TELLTALE MILITARY OPTIONS & CONTROL SYSTEMS


Slide 2:The design of the Passlock™ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the PASS-Key® system. However, the Passlock™ system eliminates the need for a key mounted resistor pellet. As long as the correct key is used, the BCM does not need reprogramming. This allows cutting of the original keys to be performed without affecting the Passlock system. The components of the Passlock™ system are as follows: The ignition lock cylinder The ignition switch The Passlock™ sensor The Body control module (BCM) The security telltale The Vehicle Control Module/Power Train Control Module (VCM/PCM) Vehicle Theft Deterrent MILITARY OPTIONS & CONTROL SYSTEMS


Slide 3:Vehicle Theft Deterrent MILITARY OPTIONS & CONTROL SYSTEMS The theft deterrent system has been incorporated into the Body Control Module (BCM). The theft deterrent is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the Power Train Control module (PCM)/Vehicle Control Module (VCM). The message enables the fuel injectors. This system is explained further in the Operators Manual


Slide 4:The purpose of the heating and A/C system is to provide heated and cooled air to the interior of the vehicle. The A/C system will also remove humidity from the interior and reduce windshield fogging. The vehicle operator can determine the passenger compartment temperature by adjusting the air temperature switch. Regardless of the temperature setting, the following can affect the rate that the HVAC system can achieve the desired temperature: Difference between inside and desired temperature Difference between ambient and desired temperature Blower motor speed setting Mode setting Climate Control System MILITARY OPTIONS & CONTROL SYSTEMS


Slide 5:The A/C LED will not illuminate unless the driver presses the A/C request switch on the HVAC control module. Otherwise, the A/C system may be running without the A/C LED indicator illuminated. The following conditions must be met in order for the PCM to turn on the compressor clutch: Ambient air temperature is above 4°C Engine speed is less than 5000 RPM A/C Pressure is between 186-2979 kPa The A/C system can be engaged by pressing the A/C switch. Max A/C can be selected by pressing the Recirculation Switch along with the A/C switch. A/C system and Controls MILITARY OPTIONS & CONTROL SYSTEMS


Slide 6:The fan knob on the left side of the control panel adjusts the fan speed. To increase airflow, turn the knob clockwise. To decrease airflow, turn it counter clockwise. To turn the fan off, turn the knob to the off position. Off If the fan is off, outside air will still enter the vehicle, and will be directed based on the position of the mode knob. The temperature can also be adjusted using the temperature knob. The outlet temperature can be adjusted individually with the two slide controls. The right air temperature switch allows the passenger to offset air discharge temperatures on the right side of the vehicle. To activate the dual zone, the passenger slides the switch to the desired offset. The right knob on the control panel allows you to choose the direction of air delivery.

Slide 7:A/C system and Controls Vent: This setting directs the air through the instrument panel outlets. Bi-Level: Air is delivered through the floor outlets as well as the instrument panel outlets. The flow can be divided between vent and floor outlets depending upon where the knob is placed between the settings. Floor: This setting directs most of the air through the floor outlets, and the rest of the air is divided between the windshield defroster outlets and the side window defroster outlets. Defog: Airflow is delivered through the floor outlets, the windshield defroster outlets and the side window defroster outlets. The airflow can be divided between floor and defrost depending upon where the knob is placed between the settings. Defrost: This setting directs most air through the windshield defroster outlets, side window defroster outlets and some through the floor outlets. Mode Knob MILITARY OPTIONS & CONTROL SYSTEMS


Slide 8:ELECTRICAL Wiring Description Several changes offered by the military options require new wiring configurations. Auxiliary wiring attaches to the original wiring providing power to the following. Blackout (B/O) Lighting 24V System Battery Equalizer Circuit Breakers and Relays Radio Communications Navigation Systems Slave Receptacle MILITARY OPTIONS & CONTROL SYSTEMS


Slide 9:Description and Operation The engine electrical options include the slave/booster receptacle, a protection contactor, and a three-battery power system. The two batteries in series provide 24V of power, which is isolated by the power converter and controlled by the circuit breakers. These step the power down to 12V from 24V. Greater power is needed for the higher load used by optional radio communications, or for compatibility with other booster/slave receptacles Maintenance The 24V power system makes each vehicle capable of accepting a power boost through its slave connection from any vehicle similarly equipped. This 24V system requires specific maintenance. 12/24 Dual Voltage Option * Please refer to the, C-31-Q44-000/MB-005, Operator’s Instruction book supplement in the vehicles glove box. This green book supplement describes the proper procedure for boosting the LUVW MIL COTS battery system. MILITARY OPTIONS & CONTROL SYSTEMS


Slide 10:Charging System Description and Circuit Operation The MILCOT vehicles are equipped with a 24V generator. The 24V generator’s electronics are isolated from the chassis ground. The 24V configuration provides sufficient capacity and reserve for 24V loads. Electrical loads can be connected indefinitely while the engine is running and a limited time when engine is OFF. The 24V system must be above 19.0 volts in order for the generator to turn ON. The generator features permanently lubricated bearings. Service should only include the tightening of mounting components. Otherwise the generator is replaced as a complete unit. 12/24 Dual Voltage Option MILITARY OPTIONS & CONTROL SYSTEMS


Slide 11:Battery Equalizer The primary function of the Battery Equalizer is to maintain battery balance or equalization charge in a predominately 24V system, which requires clean, regulated 24V power. The Battery Equalizer can deliver up to 150 amps of continuous, clean 24V current for practically any 24V load, such as two-way radios, navigations blackout lighting and other military options. 12/24 Dual Voltage Option MILITARY OPTIONS & CONTROL SYSTEMS


Slide 12:A voltmeter is installed to monitor the status of the 24-volt battery and the 24-volt generator. The voltmeter needle should be in the green band during normal load operation. During no load situation the voltmeter needle should be between the yellow and green bands.

To Prevent Fire: DO NOT operate heater where flammable or explosive materials, gases or dust may be present. DO NOT operate heater over dry grass or other dry ground cover. Switch heater off while refuelling vehicle. Switch heater off BEFORE entering fuelling stations. To Prevent Burning: NEVER Touch hot components of the heating system. Fuel Heater (Wabasto) MILITARY OPTIONS & CONTROL SYSTEMS


Slide 21:The heater requires no periodic maintenance other than a visual inspection preferably prior to the heating season, and periodic check of its air filter element to ensure the heater and all components are free from damage and in proper working condition. During the warmer months of the year when heating is not required, the heater should be switched on and allowed to run for 5 to 10 minutes once a month as a minimum. This will keep a clean fresh supply of fuel in the heater fuel system and keep all moving parts in top operation condition. The heater designed to the evaporator principle operates intermittently controlled by the temperature sensor. Fuel Heater (Wabasto) MILITARY OPTIONS & CONTROL SYSTEMS


Slide 22:In order to minimize the battery’s workload the heater switches from full-load operation to part-load operation after reaching a water temperature of 72°C. In this mode of operation the heater operates with extremely low noise and particularly low power and fuel consumption. The heater consists of the combustion air fan assembly, the control unit/heat exchanger, the burner insert, the combustion chamber, and an additional circulation pump. The coolant heater requires minimum 22.0 volts in order to operate efficiently. Voltage available that is less than 22.0 volts will result in decreased performance. At approximately 18.0 volts the coolant heater will become inoperative. Fuel Heater (Wabasto) MILITARY OPTIONS & CONTROL SYSTEMS
