Brake
Foot brake
Check the following:
• that brake pedal has proper travel,
• that brake works properly,
• that it is free from noise,
• that vehicle does not pull to one side when brake is applied.
• and that brake do not drag.
Parking brake
Check that lever has proper travel.
WARNING!
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property
damage. Be prepared to apply regular brake
quickly even if vehicle should start to move.

Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and brake
lever is pulled all the way.
Steering
• Check to ensure that steering wheel is free from instability, or abnormally heavy feeling. • Check that the vehicle does not wander or pull to one
side.
Engine
• Check that engine responds readily at all speeds.
• Check that engine is free from abnormal noise and abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting system
are free from abnormal noise and abnormal vibration or
any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter,
temperature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that ai r comes out from defroster
outlet when operating heater or air conditioning.
Set mode control lever to defroster position and fan
switch lever to “HI” position for this check.

Not Using SUZUKI Scan Tool
Current DTC mode1) Light over sunload sensor vertically with an incandescent lamp of approximately 100 W apart
from about 100 mm (3.94 in.).
NOTE
If sunload sensor is not lighted over with an
incandescent lamp, DTC B1504 is detected
as current DTC even though there is not any
malfunction.

2) Start engine.
3) Wait for 20 seconds or more after engine started and set temperature selector to 25 °C (77 °F).
4) Push AUTO switch (1) and defroster switch (2) at the same time.
5) Check DTC (3).
NOTE
• DTC flashes for 15 seconds. After that, the normal display is rest ored. To have DTC
displayed again, repeat the procedure from
Step 4.
• When more than two DTCs are detected, only DTC having the highest priority is
indicated. Therefore, after troubleshooting
the malfunction, DTC check has to be
performed again to see if any other DTC(s)
is detected.

History DTC mode
1) Turn ignition switch to ON position.
2) Set temperature selector to 25 °C (77 °F).
3) Push AUTO switch (1) and MODE (air flow) selector
(2) at the same time.
4) Check DTC (4).
NOTE
Each DTC item is displayed (lights up) for 4
seconds.
When HVAC control module detects 2 or
more DTC items, each one is displayed once
starting from the one of higher priority order.
After all DTC items being detected have been
displayed, “Ed” (3) appears on display of
HVAC control module and normal display is
restored. “Ed” means that all DTC items have
been displayed.

DTC ClearanceS7RS0B7224004
NOTE
Only history DTC(s) can be cleared. Current
DTC(s) can not be cleared unless the
problem(s) is fixed.

Using SUZUKI Scan tool
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) (1) located on underside of instrument panel
at driver’s seat side.

When no current DTC is detected, all contents displayed on display (1) of HVAC control module and
defroster indicator (2) flash at the same time.

Fail-Safe TableS7RS0B7224006
When any of the following malfunctions (DTCs) is detected, fail-safe mode is activated.
However, when HVAC control module detects normal ope ration of A/C system, fail-safe mode is cancelled.
