SPECIAL COVERAGE EXTENSION “ZA”; SPECIFIC “AIRBAG”
WARNING LIGHT ILLUMINATION (DTC B1312 ONLY).
SX4 (RW420)
2007~2011

CONDITION:

The “Airbag” light is illuminated in the instrument cluster and DTC (Diagnostic
Trouble Code) B1312 is identified as a Current DTC using the SDT. No other
DTC or condition qualifies for this coverage extension.

CAUSE:

Suzuki Motor Corporation has determined that certain 2007~2011 Suzuki SX4
vehicles may develop, due to repeated flexing, an electric disconnection
(open) in the Front Passenger Sensing System circuit within the sensor-mat
located in the passenger seat bottom cushion assembly.

CORRECTION:

In vehicles that are found to have the “Airbag” warning light ON, DTC B1312
identified as a Current DTC, and are beyond the basic warranty limits, a
special coverage extension will apply, allowing repairs to be made for
customers at no charge for parts or labor up to 10 years or 120,000 miles
from the date of first use, at authorized Suzuki Service Points.

Revised to clarify B1312 status and cushion replacement criteria.

Suzuki bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer.” They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT
assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your authorized Suzuki Service Point for
information on whether your vehicle may benefit from the information. Suzuki reserves the right to change technical specifications at any time
without prior notice.

REPAIR INFORMATION
Diagnostic Procedure for DTC B1312
1. Check and ensure there is nothing placed or
resting on the front passenger seat.
2. Turn the ignition switch to the “ON” position.
3. Check that the “AIRBAG” warning light
remains on after flashing.

4. Check that the passenger seat belt
reminder light is on (illuminated).
 If the passenger seat belt reminder
light is illuminated, go to step 5.
 If the passenger seat belt reminder
light does not illuminate, DTC
B1312 is not the cause of the
“AIRBAG” warning light. Refer to
the Suzuki Service Manual to
determine the DTC stored and
diagnose the issue.
NOTE:

Codes other than a Current B1312
are not eligible for this special
coverage extension. If the vehicle
is still within the 3/36 basic
warranty period, repair it according
to normal policies & procedures. If
the 3/36 basic warranty is expired
by either time or mileage, give your
customer an estimate for the cost
of the repair.

5. Connect SUZUKI scan tool (SUZUKI-SDT)
to data link connector (DLC).
6. Read the DTC(s) in the “Airbag” system

7. Confirm that DTC B1312 is a Current DTC
on the SDT.
 If DTC B1312 is Current, go to step 8.
 If DTC(s) other than B1312 are
present in Current and or History,
or DTC B1312 is present in History
only, clear all DTC Codes and retest. If DTC B1312 does not
become set as a Current DTC it is
not the cause of the “AIRBAG”
warning light. Refer to the Suzuki
Service Manual troubleshooting
instructions for other DTC(s) stored
and diagnose the issue.
NOTE: If DTC B1312 is not set as a Current DTC - DO NOT replace the passenger seat
cushion bottom. The vehicle is not eligible for special coverage extension at this time.
8. Replace front passenger seat cushion assembly with new one (Please refer to the EPC and
appropriate Suzuki Service Manual for replacement of the lower seat cushion on the right front
passenger seat only).
9. After completing the replacement, erase DTC using scan tool and confirm DTC Code B1312 is
no longer present real time in the vehicle.
10. After clearing the “AIRBAG” DTC(s), confirm the following:
 “AIRBAG” warning light does not remain illuminated after flashing.
 Passenger seat belt reminder light does not illuminate when turning the ignition switch to
the “ON” position.
11. The repair is complete. Return the vehicle to the customer.
