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.

Wiring Diagram
Refer to “Immobilizer Control S ystem 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 indicator lamp indication O FF 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.
Troubleshooting 4
Fuse check

3) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when the 
ignition switch is turned to ON position.
 
5 CAN communication circuit check
1) Disconnect connectors from ECM, BCM and ABS 
control module.
2) Check CAN communication circuit for open, short and  high resistance.

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.
 
Condition Possible cause Correction / Reference Item
Engine can not be started 
by turning Ignition knob
