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.

DTC Troubleshooting
NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

DTC B1084 / B1094: Driver / Passenger Side-Sensor Circuit Short to Power Circuit or OpenS7RS0B8204041
Wiring DiagramStep Action Yes No
1 1) Disconnect side-sensor connector “L11” or “L35”.
2) Disconnect SDM connector “L29”.
3) Check proper connection to SDM connector at terminals “L29-46” and “L29-47” or terminals “L29-44” and “L29-
45”.
4) Measure resistance between “L29-46 terminal and body ground, “L29-47” terminal and body ground, or “L29-44”
terminal and body ground, “L29-45” terminal and body
ground.
Special tool
(A): 09932–76010
Is each measured resistance infinity? Go to Step 3. DTC B1083: “WHT/
RED” circuit or “LT
GRN/BLK” circuit
shorted to ground.
DTC B1093: “WHT/
GRN” circuit or “LT
GRN” circuit shorted to
ground.
2 1) Check side-sensor referring to “Side-Sensor Inspection”. Is it in good condition? Substitute a known-
good SDM and recheck.
Replace side-sensor
referring to “Side-
Sensor Removal and
Installation”. If DTC still
exists, substitute a
known-good SDM and
recheck.

CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor Connections”.
• If there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The resistance measured between side-sensor circuit and power source circuit is below a specified value for specified
time.
Flow Test Description
Step 1: Check for open circuit in side-sensor circuit.
Step 2: Check for short circuit between side-sensor circuit and power supply circuit.
Step 3: Check if malfunction is in side-sensor.
