DTC Check
S6RW0C5104005
NOTE
• There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on
On-Board Diagnostic (OBD) System in
Section 1A”.
• For Euro OBD model, the MIL is turned on
when the ECM and/or TCM detect
malfunction(s). Each control module
stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool. Therefore, check both of the control
modules for any DTC with the SUZUKI
scan tool because the DTC stored in ECM
and TCM is not read and displayed at a
time. However, each of the control
modules needs not to be checked with the
CAN communication OBD generic scan
tool because the DTC stored in ECM and
TCM is read and displayed at a time. In
case using CAN communication OBD
generic scan tool, refer to “DTC Table in
Section 1A”.
1) Prepare CAN communication OBD generic scan tool
or SUZUKI scan tool.
2) Turn ignition switch to OFF position.
3) Connect scan tool to data link connector (DLC) (1).
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
4) Turn ignition switch to ON position.
5) Read DTC, pending DTC and freeze frame data
according to instructions displayed on scan tool and
print it down. Refer to scan tool operator’s manual
for further details.
If communication between scan tool and TCM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN in Section 1A”.
6) After completing the check, turn ignition switch off
and disconnect scan tool from DLC.
DTC Clearance
S6RW0C5104006
WARNING
!
When performing a driving test, select a safe
place where there is neither any traffic nor
any traffic accident possibility and be very
careful during testing to avoid occurrence of
an accident.
After repair or replace malfunction part(s), clear all DTCs
by performing the following procedure.
1) Connect SUZUKI scan tool to data link connector in
the same manner as when making this connection
for “DTC Check”.
2) Turn ignition switch to ON position.
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 clearance, turn ignition switch
OFF and disconnect scan tool from DLC.
NOTE
DTC and freeze frame data stored in TCM
memory are also cleared in the following
cases. Be careful not to clear them before
keeping their record.
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles.
Fail Safe Table

This function is provided by the safe mechanism that assures safe driveability even when the solenoid valve, sensor or
its circuit fails. The following table shows the fail safe function for each fail condition of sensor, solenoid, TCM or its
circuit.
