• The four cylinders of the engine are identified by numbers; No.1 (1), No.2 (2 ), No.3 (3) and No.4 (4) 
counted from crankshaft pulley side to flywheel side.
Engine Diagnosis General DescriptionS7RS0B1101002
NOTE
There are two types of OBD system 
depending on the vehicle specification.
For details, refer to “Precaution on On-Board 
Diagnostic (OBD) System”.
 
This vehicle is equipped with an engine and emission 
control system which are under control of ECM.
The engine and emission control system in this vehicle 
are controlled by ECM. ECM has an On-Board 
Diagnostic system which detects a malfunction in this 
system and abnormality of those parts that influence the 
engine exhaust emission. When diagnosing engine 
troubles, be sure to have full  understanding of the outline 
of “On-Board Diagnostic System Description” and each 
item in “Precautions in Diagnosing Trouble” and execute 
diagnosis according to “Engine and Emission Control 
System Check”.
There is a close relationship between the engine 
mechanical, engine cooling system, ignition system, 
exhaust system, etc. and  the engine and emission 
control system in their structure and operation. In case of 
an engine trouble, even when  the malfunction indicator 
lamp (MIL) doesn’t turn ON, it should be diagnosed 
according to “Engine and Emission Control System 
Check”.
On-Board Diagnostic System DescriptionS7RS0B1101003
NOTE
There are two types of OBD system 
depending on the vehicle specification.
For details, refer to “Precaution on On-Board 
Diagnostic (OBD) System”.
 
Euro OBD Model
ECM in this vehicle has the following functions.
• When the ignition switch is turned ON with the engine  at a stop, malfunction indicator lamp (MIL) (1) turns 
ON to check the circuit of the malfunction indicator 
lamp (1). • When ECM detects a malfunction which gives an 
adverse effect to vehicle emission while the engine is 
running, it makes the malfunction indicator lamp (1) in 
the meter cluster of the inst rument panel turn ON or 
flash (flashing only when  detecting a misfire which 
can cause damage to the catalyst) and stores the 
malfunction area in its memory.
(If it detects that contin uously 3 driving cycles are 
normal after detecting a malfunction, however, it 
makes MIL (1) turn OFF although DTC stored in its 
memory will remain.)
• As a condition for detecting a malfunction in some  areas in the system being monitored by ECM and 
turning ON the malfunction indicator lamp (1) due to 
that malfunction, 2 driving cycle detection logic is 
adopted to prevent erroneous detection.
• When a malfunction is detected, engine and driving  conditions then are stored in ECM memory as freeze 
frame data. (For the details, refer to description on 
“Freeze Frame Data”.)
• It is possible to communicate by using not only  SUZUKI scan tool (2) but also OBD generic scan tool. 
(Diagnostic information can be accessed by using a 
scan tool.)
Warm-Up Cycle
A warm-up cycle means sufficie nt vehicle operation such 
that the coolant temperature has risen by at least 22  °C 
(40  °F) from engine starting and reaches a minimum 
temperature of 70  °C (160 ° F).
