Warm air comes out of
the vents, and there is
frost on the expansion
valve
Probable cause: The expansion valve is stuck
closed
Replace the expansion valve (see page 21-80)
HVAC DTCs (see page 21-9)
Check the old expansion valve
for contamination. If
contaminants are found,
replace the A/C system
component that caused the
contamination
The temperature of the
liquid line is the same
on both sides of the
expansion valve, and
the evaporator coil or
suction line has heavy
condensation Probable cause: The expansion valve is stuck
open
Replace the expansion valve (see page 21-80)
HVAC DTCs (see page 21-9)
Check the old expansion valve
for contamination. If
contaminants are found,
replace the A/C system
component that caused the
contamination
Warm air comes out of
the vents, but
operation is normal
otherwise Probable cause: Compressor failure
Do the A/C system test (see page 21-99), and
correct any problems. If necessary, replace the
compressor (see page 21-83) HVAC DTCs (see page 21-9)
Add refrigerant oil depending
on the part you replaced
(see page 21-7)
Driver’s and
passenger’s side vent
temperatures vary by
more than 11 °C (20 °F) Probable causes: The recirculation control door
or the air mix door is malfunctioning
Do the following troubleshooting:
Recirculation control motor test (see page
21-74)
Air mix control motor test (see page 21-72) HVAC DTCs (see page 21-9)
Poor or loose connections at the
terminals
Insufficient heating 1. 2.
3.
4.
5.
6.
7.Check the coolant level (see page 10-7)
Check the radiator cap (see page 10-4)
Check the coolant temperature during normal
operation
Check the heater core inlet hose temperature:
If it is COLD, check for restrictions in the hose,
a damaged or leaking thermostat, or a
damaged or leaking water pump
If it is HOT, check for restrictions in the
heater core. Back flush or replace the heater
core
Do the air mix control motor test (see page
21-72)
Check the blower motor unit for obstructions
Check for air leaks around the ducts and vents HVAC DTCs (see page 21-9)

HDS Inputs and Commands
Input:System Menu Data List Data List Indication
22-88Multiplex Integrated Control System
System Description (cont’d)
Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List.
This should give the HDS time to update the signal on the Data List.
Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not
supported.
Make sure that the most current software is loaded.

At the initial stage of the self-diagnostic function, the beep sounds intermittently, the beeper sounds continuously
when any of the following switch inputs are switched from OFF to ON:
Cruise control main, dash lights brightness controller volume ( ), ( ) button, mph km/h switch, parking brake switch,
SEL/RESET switch, SET, RESUME, CANCEL switches, and VSA OFF switch . : ’07 TYPE S and ’08-09 models
When entering the self-diagnostic mode, the beeper sounds five times.
When entering the self-diagnostic mode, all the segments blink five times.
When entering the self-diagnostic mode, the tachometer needle sweeps from the minimum position to maximum
position, then returns to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needle returns to the minimum position, pushing the SEL/RESET
switch starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needle returns to the minimum position.
If the needle fails to sweep, or the beeper does not sound, replace the gauge control module (tach).

Special Tools Required
Electrical Noise Test
23-75
Diagnostics CD 07AAZ-SDBA100
Do this test to check for electrical noise being induced
into the audio system.
NOTE: Electrical noise may be caused by outside
sources that cannot be handled by the audio system.
Make sure you remove any cell phones and/or turn off
any aftermarket device before beginning this test.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
3. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
4. Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
5. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
6. Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level. 7. Operate any electrical device that may create
electrical noise in the audio system, including
starting the engine.
 If no abnormal noise is heard, go to individual speaker test.
 If the noise is present only during the SNR track, replace the navigation unit or audio unit.
 If the noise is heard during the digital zero or near digital zero track, check for;
– Poor ground for the audio unit, amplifier, engine or battery cable
– Pinched or shorted speaker or amplifier wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
– Other faulty components causing excessive electrical noise (ignition coils, alternator, door
lock actuators, etc.). Disconnect any suspect
components, and then replay the tracks that
were originally noisy. If the noise is gone,
check the component’s circuit and the
component.
