wheels & deals tech talk
By Jerry Bisbee – ATC Tech Trainer
[email protected]
Cascadia HVAC Operation – Part Two
Last month’s Tech Talk article provided information about how
the HVAC system in the Cascadia model Freightliner is controlled. Please refer to that article. Much of the input information that the Front Control Unit (FCU) and the Auxiliary Control
Unit (ACU) need to do their jobs comes to them over the
J-1939 datalink. Some of this input information comes from the engine’s control
unit, and some comes from the SAM Cabin. Much of this information is required by
the FCU before if will engage the AC compressor clutch. Technicians who diagnose
AC clutch engagement issues must know where these inputs come from and how
to determine whether the FCU is receiving the necessary input information.
■ Fault Code Diagnostics
Both the FCU and the ACU broadcast fault codes on the J-1939 datalink. Some
of these fault codes are triggered when the FCU does not receive the information
it needs from the J-1939 datalink. These fault codes will display on the message center on the dash when they are “active”, but the only way to read them as
“inactive” or “stored” codes is by using the ServiceLink diagnostic software that
is available to Freightliner dealerships. Refer to the Operator’s Manual in the
vehicle for instructions on how to read fault codes on the dash message
display. Table 1 lists fault codes that are stored when the FCU doesn’t receive
necessary information from the J-1939 datalink. This is not a complete list of all
the fault codes that the FCU and ACU broadcast, but these are the codes that are
related to the FCU and ACU failing to receive information that they need from the
J-1939 datalink. If one of these codes is active the FCU will not engage the AC
compressor clutch.
■ Blower Motor Diagnostics
The Cascadia uses a brushless direct current (BLDC) blower motor in both
the front and rear HVAC units. Both have four circuits connected to them. Pin
locations in the 6-pin blower motor connectors are as follows:
Pin 1 – Feedback / Diagnostic Signal – connected to FCU or ACU
Pin 2 – Not Used
Pin 3 – Ground – connected back to the SAM Cab
Pin 4 – 12V Battery – powered by the SAM Cab
Pin 5 – PWM Command – connected to FCU or ACU
Pin 6 – Not Used
Blower speed is controlled by Pulse Width Modulated (PWM) signal from the
FCU or ACU. Each controller sends a 2000 Hz pulse width signal to its respective
blower motor at Pin 5 of the blower motor connector. The pulse width of the
signal varies with the fan speed switch speed selection. The blower motor
operates between 400 and 3850 rpm.
Under normal operation, the feedback signal to the FCU and ACU, at Pin 1
of the blower motor connector, indicates blower motor speed by varying the
frequency, rpm = 20 X Frequency. The blower motor has a protection mode
built into it that will cause it to operate at a reduced speed or shutdown to prevent
damage. Any of the following conditions will cause the blower motor to enter
“protection mode”.
Over/Under Voltage – if the voltage supply to the blower motor is less
than 8.5V or more than 17V, the blower motor will enter protection mode and
shut down. The blower feedback circuit will indicate a fault and a fault will be
logged in the FCU or ACU.
Reverse Voltage Protection – the motor will not operate if the polarity of
the power and ground wires is reversed.
Current Protection – if the motor exceeds the maximum current, the
speed will be reduced until the current is within the normal range (under
23.5A). The blower feedback circuit will indicate a fault, and a fault code will be
logged in the FCU or ACU.
Temperature Protection – if the blower’s internal temperature sensor
indicates that the temperature inside the motor is too high, the blower speed will
be reduced to 1000rpm to reduce the load on the motor. A second comparison is
made between the temperature and the maximum limit. If the temperature is still
too high the blower speed is further reduced to 500 rpm and another comparison is made between the temperature and the maximum limit. If the temperature
is still too high the motor will shut down until it has cooled. The blower feedback
circuit will indicate a fault and a fault code will be logged in the FCU or ACU.
Visit the Freightliner booth #11117 at this
years Great American Trucking Show, August
20-22, in Dallas, Texas. As part of the show
we will have special guests Kurt Grote, Henry
Albert, and Dick McCorkle with us in the
booth. These drivers are currently testing the
new Freightliner Cascadia and are “blogging”
about their travels at

If the blower motor has entered protection mode, the blower speed feedback
signal becomes a diagnostic signal to the FCU and ACU by setting its frequency
to 10 Hz and varying the duty cycle of the signal to indicate the cause of the protection mode. Table 2 illustrates the various duty cycles of the diagnostic signal
and the fault conditions they represent. The frequency and duty cycle of this signal may be measured with a digital multimeter that has the capability to measure
frequency and duty cycle. Table 3 illustrates the fault codes that may be logged
in the FCU or ACU when the blower motor enters one of the protection modes.
■ FCU Calibration
If the FCU is replaced or any of the door actuators on the front HVAC unit are
removed or replaced the FCU must be manually calibrated. To perform the calibration routine:
1. Turn the ignition ON but do not start the engine.
2. Set the blower speed control to full left or “OFF”.
3. Set the temperature control to full right or “HOT”.
4. Set the mode control knob to full left or “FACE”.
5. Press the A/C and RECIRC buttons simultaneously until the A/C and
RECIRC indicators begin flashing simultaneously.
6. The calibration process will begin and continue until the A/C and
RECIRC indicators stop flashing.
Future Tech Talk articles on the Cascadia HVAC system will cover
performance testing and refrigerant system pressure diagnostics.
