• Do not leave ignition key in a place where
temperature is high. High temperature may cause
damage to the transponder built in the ignition key. • Do not turn ignition switch to ON position by bringing
radio antenna close to coil antenna. Or, the
immobilizer control syst em may detect some
abnormal condition and prevent the engine from
starting.
General Description
Immobilizer Control System IntroductionS7RS0BA301001
The immobilizer control system is an anti-theft device that immobilizes the vehicle. It stops the engine from working
and prevents the vehicle from being stolen. It mainly consists of the following components.
• Engine Control Module (ECM)
• Immobilizer control module (ICM) with the built-in coil antenna
• Ignition key with the built-in transponder
A code called the transponder code is memorized in the tran sponder. And, the code is registered with ECM. Basically,
when the ignition switch is turned ON, ECM reads the code by the coil antenna. Then, if the code in transponder in the
ignition key does not match with the one registered with ECM, ECM stops the operati on of the fuel injection so as not
to start up the engine and turns the immobilizer indi cator lamp ON and OFF using CA N communication lines. In the
case of the vehicle equipped with the keyless start system , in addition to the above operation, ECM makes the
immobilizer indicator lamp ON and OFF when it detects a trouble related to ID code verification of the keyless start
system.

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.

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
1) Turn ignition switch to OFF position.
2) Check for fuse blown at combination meter circuit fuse in
junction block assembly.
Is fuse in good condition? Go to Step 5. Replace fuse and check
for short to power or
ground circuit.
5 CAN communication circuit check
1) Disconnect connectors of all control modules
communicating by means of CAN.
2) Check CAN communication circuit between control modules for open, short and high resistance.
Is each CAN communication circuit in good condition? Go to Step 6. Repair circuit.
6 Combination meter power and ground circuit check
1) Remove combination meter referring to “Combination
Meter Removal and Installation in Section 9C”.
2) Check for proper connection to combination meter connector terminals.
3) If OK, then turn ignition switch to ON position, Check terminal voltage of combination meter between power
supply and ground terminal. Refer to “Combination
Meter Circuit Diagram in Section 9C”.
Is it 10 – 14 V? Substitute a known-
good combination meter
and recheck. If
immobilizer indicator
lamp still remains OFF,
substitute a known good
ECM and recheck.
Repair power supply
and/or ground circuit.

1 DTC check of ECM
1) Start engine and recheck DTC of ECM while engine
running.
Is DTC P1674, P1675, P1678 and/or P1685 detected? Go to applicable DTC
diag. flow.
Go to Step 2.
2 CAN communication circuit check
1) Disconnect connectors from ECM, BCM, ABS control
module and combination meter.
2) Check CAN communication circuit for open, short and high resistance.
• Between ECM and ABS control module
• Between BCM and ABS control module
• Between BCM and combination meter
Is each CAN communication circuit in good condition? Substitute a known-
good combination meter
