On-Board Diagnostic System DescriptionS6RW0D5101005
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 automatic transaxle control system, TCM has the
following functions.
• For Euro OBD model, when the ignition switch is
turned ON with the engine at a stop, MIL (1) turns ON
to check the bulb of the MIL.
• For Euro OBD model, when TCM detects a
malfunction in A/T control system TCM desires turning
on MIL and stores malfunction DTC in TCM memory.
(If it detects that continuously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL turn OFF although DTC stored in its
memory will remain.)
• For Euro OBD model, it is possible to communicate
with TCM through data link connector (DLC) (2) by
using not only SUZUKI scan tool (3) but also CAN
communication OBD generic scan tool. (Diagnostic
information can be checked and erased by using scan
tool.)
• For non-Euro-OBD model, when ignition switch is
turned ON and no malfunction in A/T control system is
detected, transmission warning light (4) lights for
about 2 seconds after ignition switch is turned ON and
then goes OFF for bulb check.• For non-Euro-OBD model, when TCM detects a
malfunction in A/T control system, it indicates
transmission warning light (4) and stores malfunction
DTC in its memory.
• For information about the following items, refer to “On-
Board Diagnostic System Description in Section 1A”.
– Warm-up cycle
– Driving cycle
– 2 driving cycle detection logic
– Pending DTC
– Freeze frame date

Malfunction Indicator Lamp (MIL) CheckS6RW0D5104003
Refer to the same item in “Malfunction Indicator Lamp (MIL) Check in Section 1A” for checking procedure.
Transmission Warning Light Check (Non-Euro-OBD model)S6RW0D5104053
1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF.
If anything faulty is found, advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON (Non-Euro-OBD Model)” or “Transmission Warning Light Circuit Check – Light Remains “ON”
at Ignition Switch ON (Non-Euro-OBD Model)”.
DTC TableS6RW0D5104004
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 non-Euro-OBD model, some of DTC No. with (*) mark in the following table can not be detected
by TCM depending on vehicle specification and local regulation.
• With the CAN communication OBD generic scan tool, DTC No. with delta (U) mark in the following
table can not be read.
• A: Driving cycles when MIL lighting and storing DTC in TCM memory for Euro OBD model.
• B: Driving cycles when transmission warning light lighting and storing DTC in TCM memory for non-
Euro-OBD model.
• 1 driving cycle: MIL or transmission warning light lights up when DTC is detected during 1 driving
cycle.
• 2 driving cycles: MIL or transmission warning light 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.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.

Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”
• Charge warning lamp ----- Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp ----- Operation “Oil Pressure Warning Light Symptom Diagnosis in
Section 9C”
• Engine coolant temp. meter ----- Operation “Engine Coolant Temperature (ECT) Meter
Symptom Diagnosis in Section 9C”
• Other parts that can be checked visuallyInspection item Referring
