and liquid line temperature. Using the Charge Deter-
mination Chart (Fig. 3), determine whether the
refrigerant system is operating within the Proper
Charge Range.
(a) If the refrigerant system is operating in the
Undercharged area of the chart, add 0.057 kilo-
gram (0.125 pound or 2 ounces) of refrigerant to
the system.
(b) If the refrigerant system is operating in the
Overcharged area of the chart, reclaim 0.057 kilo-
gram (0.125 pound or 2 ounces) of refrigerant from
the system.
(6) Recheck the system charge level following each
refrigerant adjustment. Continue this process until
the system readings are in the Proper Charge Range
area on the Charge Determination Chart (Fig. 3).DIESEL SUPPLEMENTAL
HEATER - DCHA
DESCRIPTION
Vehicles equipped with the optional diesel engine are
also equipped with a supplemental heater unit. This
unit is mounted under the vehicle and operates similar
to an oil fired furnace. The heater burns small
amounts of fuel to provide additional heat to the cool-
ant. Coolant is routed from the engine, to the supple-
mental heater, and then to the front heater core. This
provides additional heat to the passenger compart-
ment. The system is interfaced to the vehicles on-board
computer systems and DRB-III diagnostics.

REFRIGERANT (Continued)

OPERATION
The supplemental heater unit is activated via the
temperature slide control or knob on the vehicle HVAC
control unit. If the control slide or knob is moved to or
above the upper set point the heater is activated. The
unit can operate in a full or partial load range as well
as an idle mode all dependent on the engine coolanttemperature. The heater unit will also turn off if the
HVAC temperature control is lowered to less than the
lower set point. The heater unit can take up to three
minutes to completely shut down when either the
heater temperature is set below the lower set point or
the vehicle ignition is shut down.
DIAGNOSIS AND TESTING - DIESEL SUPPLEMENTAL HEATER - DCHA
The following table lists possible fault symptoms of
diesel fueled heaters.
SYMPTOM POSSIBLE CAUSES
Smell of diesel fuel Check heater system integration in vehicle's fuel system. Check fuel
lines for leakage, kinks or obstructions. If OK, Inspect the inlet muffler,
drain as necessary. Re-test the unit and re-inspect. Inspect the
exhaust tube and heater unit for the presence of external fuel. If a
volume is observed on the unit or in the exhaust tube or after draining
and testing. Remove heater unit from vehicle and repair or replace
components as required.
Heater does not achieve full load
operation.Check heater operation with DRB-III and replace components as
required.
Continuous white smoke from heater
exhaust during combustion operation.Check heater operation with DRB-III and replace components as
required. White smoke is typical in extreme weather conditions.
Heater can not be switched off. Check heater operation with DRB-III and replace components as
required.
Heater does not operate. Diagnosis cabin heater ECU using the DRB-III and the procedures
listed in Vehicle Performance under Cabin Heater Diagnosis in Group
18.
Loss of coolant (Leakage) or heater
develops smoke during combustion
operation and exhaust has an
extremely sweet smell.Inspect coolant hoses for leakage, kinks or loose hose connection.
Inspect the exhaust tube assembly for continuous flow, if OK there is
an internal heater leak and unit should be inspected and components
should be replaced as required.
Loss of fuel (dripping). Check heater system integration in vehicles fuel system. Check fuel
line connection for leakage. If OK there is an internal leak and unit
should be inspected and replaced as required.
