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
