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.

4) Turn ignition switch to ON position.
5) Erase DTC according to instructions displayed on SUZUKI scan tool.
NOTE
To know how to use SUZUKI scan tool, refer
to operator’s manual for SUZUKI scan tool.

6) After completing the clearance, turn ignition switch to OFF position, and then di sconnect SUZUKI scan
tool from DLC.
Not Using SUZUKI Scan Tool 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 to have history DTC displayed.
4) Push MODE (air flow) selector (2) and OFF switch (3) at the same time while history DTC is displayed.
5) Check that “CL” (4) appears on display. “CL” means that DTC has been cleared.

Installation
S7RS0B7226011
Refer to “Blower Motor Resistor Removal and
Installation in Section 7A”.
Blower Motor Controller InspectionS7RS0B7226012
1) Check internal circuit of controller for resistance as follows.
a) Measure resistance between “1” terminal and “2” terminal of blower motor controller.
Blower motor cont roller resistance
“1” – “2”: approximately 10 k Ω at 25 °C (77 °F)
If resistance does not meet above specification,
replace blower motor controller.
b) Using ohmmeter, connect its positive terminal to “3” terminal of blower motor controller and
negative terminal to “1” terminal of blower motor
controller and check that there is no continuity.
2) Check controller for operation as follows. a) Using service wire, connect battery positive terminal to “3” terminal of blower motor controller
and battery negative terminal to “1” terminal of
blower motor controller.
b) Using bulb (3.4 W) (5) and service wire, connect battery positive terminal to “3” terminal of blower
motor controller as shown figure.
c) Arrange 3 new 1.5 V batteries (6) in series (check that total voltage is 4.5 – 5.0 V) and
connect its positive term inal to “2” terminal of
blower motor controller and negative terminal to
“1” terminal of blower motor controller.
Then, check that bulb lights. If bulb does not light
under the above conditions, replace blower
motor controller.

Downloaded from www.Manualslib.com manuals search engine Seat Belts: 8A-2
Seat Belt with ELR
The seat belt with emergency locking retractor (ELR) is
designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any
further) when any of the following items is detected as
exceeding each set value;
• Speed at which the webbing is pulled out of the retractor.
• Acceleration or deceleration of the vehicle speed.
• Inclination.
Seat Belt with A-ELR
The automatic and emergency locking retractor (A-ELR)
works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an
Automatic Locking Retractor (ALR ) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out
from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further,
unless it is wound all the way back into the retractor,
which releases the lock and allows the webbing to be
pulled out.
Seat Belt with ELR and Pretensioner
The seat belt with ELR and a pretensioner has a
pretensioner mechanism whic h operates in linkage with
the air bag in addition to the described ELR.
The pretensioner is incorporated in retractor assembly
and controlled by SDM as one of air bag system
components. It will be activated at the same time as the
driver and passenger air bag module when an impact at
the front of vehicle exceeds the specified value.
When servicing seat belt (retractor assembly) with
pretensioner, be sure to observe all WARNINGS and
CAUTIONS and “Precautions on Service and Diagnosis
of Air Bag System in Section 8B”. CAUTION!
Do not reuse the seat belt pretensioner
(retractor assembly) that has activated.
Replace it with a new seat belt assembly and
buckle together as a set. For checking
procedure of its activation, refer to “Repair
and Inspection Required after Accident in
Section 8B”.

Seat Belt Remainder
When driver’s seat belt is unfastened (under the
following conditions), seat belt reminder light and
warning buzzer inform that driver’s seat belt is
unfastened. Seat belt reminder light located in
combination meter and warning buzzer located inside
BCM operate as follows:
• Seat belt reminder light comes on when driver’s seat belt is unfastened while igni tion key switch is at ON
position.
• If vehicle speed exceeds 15 km/h with seat belt unfastened, warning buzzer operates for
approximately 95 seconds and seat belt reminder light
flashes synchronously with buzzer. When warning
buzzer stops operating, seat belt reminder light is
turned on.
• If driver’s seat belt state is changed from “fastened” to “unfastened” while vehicle speed is above 15 km/h,
warning buzzer operates for approximately 95
seconds and seat belt reminder light flashes
synchronously with buzzer. When warning buzzer
stops operating, seat belt reminder light is turned on.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS7RS0B8104001
After an accident, whether the seat belt pretensioner has been activated or not, be sure to perform checks and repairs
described on “Repair and Inspection Required after Accident in Section 8B”.
