DTC ClearanceS7RS0B1104004
NOTE
There are two types of OBD system 
depending on the vehicle specification.
For details, refer to “Precaution on On-Board 
Diagnostic (OBD) System”.
 
Using Scan Tool1) Connect OBD generic scan to ol or SUZUKI scan tool 
to data link connector in the same manner as when 
making this connection for DTC check.
2) Turn ignition switch OFF and then ON.
3) Erase DTC and pending DTC according to  instructions displayed on scan tool. Refer to scan 
tool operator’s manual for further details.
4) After completing the clear ance, turn ignition switch 
OFF and disconnect scan tool from data link 
connector.
NOTE
DTC and freeze frame data stored in ECM 
memory are also cleared in the following 
cases. Be careful not to clear them before 
keeping their record.
• When power to ECM is cut off (by  disconnecting battery cable, removing 
fuse or disconnecting ECM connectors).
• When the same malfunction (DTC) is not  detected again during 40 engine warm-up 
cycles. (See “Warm-Up Cycle” of “On-
Board Diagnostic System Description”.)
 
Without Using Scan Tool (Hong Kong Model)
1) Turn ignition switch to OFF position.
2) Disconnect battery negative cable for specified time  below to erase diagnostic trouble code stored in 
ECM memory and reconnect it.

• There are two types of OBD system depending on the vehicle specification.
• For details, refer to “Precaution  on On-Board Diagnostic (OBD) System”.
• For non-Euro-OBD model, some of DTC No. with delta (  U) mark in the following table can not be 
detected by ECM depending on vehicl e specification and local regulation.
• DTC with square (  †) mark in the following table can be detected only for Hong Kong model.
• DTC with circle (  {) mark in the following table can be detected only for Euro OBD model and Hong 
Kong model.
• For Euro OBD model, with the generic scan tool, onl y star (*) marked DTC No. in the following table 
can be read.
• 1 driving cycle: MIL lights up when DTC is detected during 1 driving cycle.
• 2 driving cycles: MIL lights up when the same DTC is detected also in the next driving cycle after  DTC is detected and stored temporarily in the first driving cycle.
• *2 driving cycles: MIL blinks or lights up. Refer to “DTC P0300 / P0301 / P0302 / P0303 / P0304: Random / Multiple

Scan Tool DataS7RS0B1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles 
by using a scan tool, use them as re ference values. Even when the vehicle is  in good condition, there may be cases 
where the checked value does not fall within each specified  data range. Therefore, judgment as abnormal should not 
be made by checking with these data alone.
Also, conditions that can be checked by  the scan tool are those detected by ECM and output from ECM as commands 
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool. 
Be sure to use the timing light  to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on  On-Board Diagnostic (OBD) System”.
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the  neutral position and A/T gear to the “Park” position  and pull the parking brake fully. Also, if nothing 
or “no load” is indicated, turn O FF A/C (if equipped with A/C), all electric loads, P/S and all the other 
necessary switches.
