DTC Check

S6JB0B5104004

NOTE
The MIL is turned on when the ECM and/or
TCM detect malfunction(s). Each ECU 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 ECUs for any DTC with the scan
tool because the DTC stored in ECU and TCM
is not read and displayed at a time. However,
each of the ECUs needs not to be checked
with the generic scan tool because the DTC
stored in ECM and TCM is read and displayed
at a time.

1) Turn ignition switch OFF.
2) Connect SUZUKI scan tool to data link connector

(DLC).

Special tool
(A): SUZUKI scan tool

3) Read DTC according to instructions displayed on

SUZUKI scan tool and write it down. Refer to
SUZUKI scan tool operator’s manual for further
details.

4) After completing the check, turn ignition switch OFF

and disconnect SUZUKI scan tool from data link
connector (DLC).

DTC Clearance

S6JB0B5104005

NOTE
DTC and freeze frame data stored in TCM
memory are also cleared in following cases.
Be careful not to clear them before keeping
their record.
• When power to TCM is cut off (by

disconnecting battery cable, removing
fuse or disconnecting TCM connector).

• When the same malfunction (DTC) is not

detected again during 40 engine warm-up
cycles.

1) Turn ignition switch OFF.
2) Connect SUZUKI scan tool to data link connector

(DLC) (1).

Special tool
(A): SUZUKI scan tool

3) Clear DTC according to instructions displayed on

SUZUKI scan tool. Refer to SUZUKI scan tool
operator’s manual for further details.

4) Clear DTC according to instructions displayed on

SUZUKI scan tool. Refer to SUZUKI scan tool
operator’s manual for further details.

Fail Safe Table

S6JB0B5104006

When any of the following DTCs is detected, TCM enters fail-safe mode as long as malfunction continues to exist but
that mode is canceled when TCM detects normal condition after that.
