On-Board Diagnostic System Description (Self-diagnosis Function)S7RS0BA301003
ECM diagnoses if there is any trouble with the immobilizer control system. The diagnostic information is stored as the
diagnostic trouble code (DTC) in ECM. To read the di agnostic information, use SUZUKI scan tool referring to
“Diagnostic Trouble Code (DTC) Check”.
With the ignition switch turned ON (but the engine at stop) regardless of the condition of the engine and emission
control system, ECM indicates whether ther e is any trouble with the immobilizer control system or not by either lighting
ON or flashing ON and OFF t he immobilizer indicator lamp.
Immobilizer indicator lamp lights ON:
No trouble exists in the immobilizer control system. (After starting up the engine, the light turns OFF.)
Immobilizer indicator lamp flashes ON and OFF:
There is some trouble in the immo bilizer control system. Its diagnostic information is stored in ECM.

Scan Tool DataS7RS0BA304005
Scan Tool Data Definitions
NUMBER OF LEARNT KEY
0 – 4 PCS: The number of the transponder code in the transponder built in the ignition key that is registered with ECM
NOTE
A maximum of four transponder codes can be registered with ECM. Therefore, the maximal value
should be 4.

INPUT YEAR
20**: The year in which the transponder code in the transpon der built in the ignition key is registered with ECM
INPUT MONTH
1 – 12: The month in which the transponder code in the transpond er built in the ignition key is registered with ECM
Immobilizer Indicator Lamp Does Not Come ON with Ignition Switch ON and Engine StopS7RS0BA304006
Wiring Diagram
Refer to “Immobilizer Control System Wiring Circuit Diagram”.
Circuit Description
When the ignition switch is turned ON, ECM read the code by the coil antenna from ignition key. Then if the code in
transponder in the key match with the one registered with ECM, transmits indication ON signal of immobilizer indicator
lamp to combination meter in order to turn immobilizer indicator lamp on. And then, combination meter turns
immobilizer indicator lamp on. When th e engine starts to run and no malfunction is detected in the system, ECM
transmits immobilizer indi cator lamp indication OFF signal to combination meter in order to turn immobilizer indicator
lamp off. And then, comb ination meter turns immobilizer indicator lamp off, but if a malfunction was or is detected,
immobilizer indicator lamp is flashes ON and OF F, when ignition switch turn to ON position.

Step Action YesNo
1 Immobilizer indicator lamp power supply check
1) Turn ignition switch to ON position.
Do other warning lights come ON? Go to Step 2.
Go to Step 4.
2 DTC check of ECM
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch and check DTC.
Is DTC P1674, P1675, P1678 and/or P1685 detected? Go to applicable DTC
diag. flow.
Go to Step 3.
3 DTC check of BCM
1) Check BCM for DTC referring to “DTC Check in Section
10B”.
Is DTC U1073, U1100 and/or U1144 detected? Go to applicable DTC
diag. flow.
Substitute a known-
good combination meter
and recheck. If
immobilizer indicator
lamp still remains OFF,
substitute a known good
ECM and recheck.

Keyless Engine Start Function
NOTE
Before performing symptom diagnosis procedure for keyless engine start system, check that engine
starts by using ignition key. If it cannot be started by using ignition key, go to “Engine Symptom
Diagnosis in Section 1A”.

Keyless Start System Operation InspectionS7RS0BA504011
Keyless engine start operation
1) Sit in driver seat with re mote controller carried with
you.
2) Check that all doors are closed and ignition key is not inserted in ignition key cylinder.
3) While pushing ignition knob switch (1) of steering lock unit, check if ignition knob switch can be turned
from its lock position.
If key indicator lamp (2) in combination meter lights
in blue and ignition knob switch can be turned from
its lock position in this check, keyless engine start
operation is in good condition.
If key indicator lamp in combination meter lights in
red and ignition knob switch cannot be turned from
its lock position in this check, go to “Keyless Start
System Check”.
NOTE
Pushing ignition knob switch for 5 seconds
or longer causes function to protect steering
lock releasing solenoid against heat to work.
Then steering lock unit stops energizing
solenoid, preventing ignition knob switch
from turning. At the same time, key indicator
lamp in combination mete r turns off. In such
case, take your hand off from ignition knob
switch once and operate it again.
