Tightening torque
Manual select lever nut (a): 13 N·m (1.3 kgf-m,
9.5 lb-ft)
95) Install engine mounting LH bracket (1). Tighten
engine mounting LH bracket bolts and nut to
specified torque referring to “Engine Mountings
Components in Section 1D”.
96) Install torque converter (3) noting the following
points.
CAUTION!
• Before installing converter, make sure that
its pump hub portion is free from nicks,
burrs or damage which may cause oil seal
to leak.
• Be very careful not to drop converter on oil
pump gear. Damage in gear, should it
occur, may cause a critical trouble.

• Install torque converter aligning grooves (1) of
torque converter and projection (2) of oil pump
drive gear.
• Install torque converter, using care not to damage
oil seal of oil pump.
• After installing torque converter, check that
distance “a” is within specification.
Torque converter installing position
“a”: More than 19.9 mm (0.783 in.)
• Check torque converter for smooth rotation.
• Apply grease around cup (6) at the center of
torque converter.

Precautions in Diagnosing TroubleS6RW0D7220002
• Do not disconnect couplers from HVAC control module, battery cable from battery, HVAC control module ground
wire harness from body or main fuse before confirming diagnostic information (diagnostic trouble code) stored in
HVAC control module memory.
• Diagnostic information (diagnostic trouble code) stored in HVAC control module can be checked by display of HVAC
control module. Also, it can be checked by using SUZUKI scan tool. Before checking diagnostic information
(diagnostic trouble code), read this manual and operator's manual for SUZUKI scan tool to know how to read
diagnostic information (diagnostic trouble code).
• When trouble is diagnosed using diagnostic information (diagnostic trouble code) on display of HVAC control
module, keep in your mind that each diagnostic information (diagnostic trouble code) has priority, and only
diagnostic information (diagnostic trouble code) which has the highest priority is indicated. Therefore, after
troubleshooting the malfunction, make sure if there exists any other diagnostic information (diagnostic trouble
code).
• Be sure to read “Air Bag Warning in Section 00” before inspection.

General Description
Auto A/C System DescriptionS6RW0D7221001
The automatic type air conditioning system (auto A/C) is provided with the function to automatically control the inside
air temperature, fan speed, air flow outlet direction and air intake position by HVAC control module in addition to
functions of the manual type air conditioning system (manual A/C). Once the inside air temperature is set using the
temperature selector, HVAC control module automatically controls the inside air temperature at the constant level at all
times based on the inside air temperature, outside air temperature, amount of sunlight and engine coolant
temperature detected respectively by the inside air temperature sensor, outside air temperature sensor, sunload
sensor and ECT sensor. For the electronic control system components location, refer to “Electronic Control System
Components Location”. For the A/C system components location, refer to “A/C System Major Components Location”.

HVAC Control DescriptionS6RW0D7221002
Temperature Control
HVAC control module calculates the target temperature
control door position based on signals from the
temperature selector, inside air temperature sensor,
outside air temperature sensor and sunload sensor and
controls the temperature control actuator so that the
current position of the temperature control door matches
its target position.
Fan Speed Control
HVAC control module calculates the target blower fan
speed based on signals from the temperature selector,
inside air temperature sensor, outside air temperature
sensor, ECT sensor and sunload sensor, compares it
with the current blower fan speed inputted from the
blower motor controller to control the current blower fan
speed to the target level.
Air Flow Outlet Control
HVAC control module calculates the target temperature
control door position based on signals from the
temperature selector, inside air temperature sensor,
outside air temperature sensor, ECT sensor and sunload
sensor. Using thus obtained target temperature control
door position, it further calculates the target air flow
control door position and controls the air flow control
actuator so that the current air flow control door position
becomes the target position.
Air Intake Position Control
HVAC control module determines the position of the air
intake control door based on signals from the
temperature selector, inside air temperature sensor,
outside air temperature sensor and sunload sensor and
selects any of the following positions by controlling the
position of the air intake control door.
• FRESH position (FRE)
• RECIRCULATION position (REC)
• MIX position (MIX)A/C Compressor Relay Control
HVAC control module outputs A/C switch ON signal to
ECM via BCM when the vehicle state satisfy conditions
described below.
• A/C switch is ON
• Evaporator temperature is higher than specified value
• Evaporator temperature sensor malfunction is not
detected
Communication of ECM and BCM is established by CAN
(Controller Area Network). (For more detail of CAN
communication, refer to “CAN Communication System
Description in Section 1A”).
ECM turns ON the A/C compressor relay when the
vehicle state satisfy conditions described below.
• A/C switch ON signal is inputted
• A/C refrigerant pressure is within specified range
• Engine speed is within specified range
• Engine coolant temperature is lower than specified
value
• Throttle opening is lower than specified value
• Vehicle is not in either state of starting or quick
acceleration
• ECT sensor malfunction is not detected
• A/C refrigerant pressure sensor malfunction is not
detected
Condenser Cooling Fan Relay Control
ECM turn ON the condenser cooling fan relay at the
same time when ECM turn ON the A/C compressor
relay.
