DTC Check

S6JB0B8204004

Using SUZUKI Scan Tool

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).

Using Monitor Connector (If Equipped)

1) Using service wire (3), ground diagnosis switch

terminal (2) in “AIR BAG” monitor coupler (1).

2) Read DTC from flashing pattern of malfunction

indicator lamp (“AIR BAG” warning light) Referring to
“DTC Table”.
If light does not indicate DTC, proceed to ““AIR BAG”
Warning Light Cannot Indicate Flashing Pattern of
DTC (If Equipped with “AIR BAG” Monitor Coupler)”.

3) After completing the check, turn ignition switch to

OFF position and disconnect service wire from “AIR
BAG” monitor coupler.

Example: When driver air bag initiator circuit resistance high (DTC B1031) is set

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)
