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 which operates in linkage with
the air bag in addition to the described ELR.The pretensioner is incorporated in retractor 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) 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) that has activated. Replace it with
a new seat belt 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 inform that
driver’s seat belt is unfastened. Seat belt reminder light
located in combination meter located inside BCM
operate as follows:
• Seat belt reminder light comes on when driver’s seat
belt is unfastened while ignition key switch is at ON
position.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS6RW0D8104001

Step Action Yes No
1“AIR BAG” warning light check
1) Turn ignition switch to ON position.
Does “AIR BAG” warning light come ON steady?Go to ““AIR BAG”
Warning Light Comes
ON Steady”.Go to Step 2.
2Scan tool condition check
1) Make sure that SUZUKI scan tool is as follows.
• Correct PCMCIA card (software) is used.
• There are no deformation and wear for DLC cable
terminals.
• Connection for DLC cable terminals is in good
condition.
Are they OK?Go to Step 3. Repair or replace
defective part.
3Scan tool operation check
1) Check DLC terminal for deformation and wear.
2) If it is in good condition, connect SUZUKI scan tool to
DLC with ignition switch turned OFF.
3) Check if communication is possible by making
communication with other control modules (BCM, ABS
control module, HVAC control module (auto A/C model)
or P/S control module).
Is it possible to communicate with the other control
modules?Go to Step 4. Go to Step 6.
4Serial communication circuit check
1) With ignition switch turned OFF, disconnect SDM
connector “L04” and check for proper connection at
SDM connector terminal.
2) If connections are OK, check that “Serial data circuit” is
as follows.
• Wiring resistance of “Serial data circuit” wire between
DLC and SDM connector is less than 1 Ω.
Is it resistance less than 1
Ω?Go to Step 5. “Serial data circuit” is
open or high resistance.
5SDM power and ground circuit check
1) Check power supply circuit and ground circuit for SDM
referring to “SDM Power Supply and Ground Circuit
Check”.
Is check result in good condition?Substitute a known-
good SDM and recheck.Repair or replace
defective circuit.
6DLC power and ground circuit check
1) Check power supply circuit and ground circuit for DLC as
follows.
• Voltage of “DLC power supply circuit” between DLC
terminal and vehicle body ground is 10 – 14 V with
ignition switch turned ON.
• Wire resistance of each “DLC ground circuit” between
DLC terminal and vehicle body ground is less than
1Ω.
Is check result in good condition?Go to Step 7. Repair or replace
defective circuit.
