Inspection of HVAC Control Module and Its CircuitS7RS0B7224026
HVAC control module and its circuits can be checked at HVAC control module wiring couplers by measuring voltage.
CAUTION!
HVAC control module can not be checked by itself. It is strictly prohibited to connect voltmeter to
HVAC control module with couplers disconnected from it.

Voltage Check
1) Remove HVAC control module referring to “HVAC Control Module Removal and Installation”.
2) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when ignition
switch is ON.

DTC CheckS7RS0B8204004
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
If communication between scan tool and SDM is not
possible, check if scan tool is communicable by
connecting it to SDM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. 5) After completing the check,
turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).
DTC ClearanceS7RS0B8204005
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) (1) in the same manner as when making this
connection for DTC check.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Erase DTC according to instructions displayed on
SUZUKI scan tool. Refer to SUZUKI scan tool
operator’s manual for further details.
5) After completing the clearance, perform “DTC Check” and confirm that normal DTC (NO CODES)
is displayed and not malfunction DTC.
6) Turn ignition switch to OFF position and disconnect SUZUKI scan tool from DLC.
NOTE
If DTC B1013, DTC B1 021 or DTC B1027 is
stored in SDM, it is not possible to clear DTC.

Headlight Bulb ReplacementS7RS0B9206002
WARNING!
• To avoid danger of being burned, don’t touch when the bulb is hot.
• Don’t touch glass surface of bulb, to avoid deteriorate as the case may be unclear
when bulb light on at dirty condition.

1) Disconnect negative (–) cable at battery.
2) Disconnect coupler from bulb.
3) Remove socket cover (1).
4) Replace bulb (2) and assemble all removed parts.
Headlight Aiming Adjustment with ScreenS7RS0B9206003
NOTE
• Unless otherwise obligated by local regulations, adjust headlight aiming
according to the following procedure.
• After replacing headlight housing, be sure to adjust aiming.
• When inspecting and adjusting headlight with leveling system, make sure to set the
leveling switch to “0 ” position with ignition
switch turned ON.

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall (screen) (1) ahead of headlight surface.
Distance “a”
10 m (32.8 ft.)
• Adjust air pressure of all tires to the specified value respectively.
• Bounce vehicle body up and down by hand to stabilize suspension.
• Carry out aiming with a driver aboard.
Driver’s weight
75 kg (165 lb)
2) Check to see if hot spot (high intensity zone) of each low beam axis falls as shown in figure.
NOTE
If the headlights interfere each other and
make it hard to see the cut line clearly, cover
the headlight on one side. This helps to make
aiming adjustment easier.

Hot spot specification
Angle “b”: 0.75 ° (Specification)
Calculated distance “H”: Approx. 130 mm (5.15
