Immobilizer Indicator Lamp Remains ON after Engine StartsS7RS0BA304007
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.
Step Action Yes No
Step
Action YesNo
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
and recheck. If
immobilizer indicator
lamp still remains ON,
substitute a known-
good ECM and recheck.
Repair circuit.

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.
