BCM Reception Data
Theft Deterrent LightS6RW0DA201003
The information display or clock (1) of this vehicle includes a theft deterrent light (2) for the theft preventive purpose.
The BCM makes the theft deterrent light flash at certain intervals after the ignition switch is turned off until it is turned
on again. Also, DTCs stored in BCM can be checked by reading the flashing patterns of the theft deterrent light when
diagnosing troubles.
Security Alarm Description (If Equipped)S6RW0DA201005
Operation
The security alarm system provides a warning of an abnormal condition to those who are around. Its operation is as
follows. While the system is in the stand-by mode (when 20 seconds or more elapsed after the door is locked using a
keyless entry transmitter or door request switch), BCM monitors door lock status, door switch status and battery power
supply voltage. When it detects an abnormal condition (door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily), it activates the
warning buzzer (located in BCM), theft deterrent light, hazard warning relay and horn relay.
The security alarm system has 2 selectable modes.
• A mode: No operation
• B mode: Theft deterrent light blinks, hazard warning lights blink, warning buzzer (located in BCM) sounds and horn
sounds

Immobilizer Indicator Light Does Not Come ON with Ignition Switch ON and Engine StopS6RW0DA304006
Wiring Diagram
Refer to “Immobilizer Control System Wiring Circuit Diagram”.
Circuit Description
When the ignition switch is turned ON, ECM transmits the indication ON signal to the combination meter to turn ON the
immobilizer indicator light in case that there is not any problem with the immobilizer control system. Then, the
combination meter turns ON the light. When the engine is started up, ECM transmits the indication OFF signal to the
combination meter to turn OFF the light. Then, the combination meter turns OFF the immobilizer indicator light.
However, in case that there is some trouble with the immobilizer control system, the immobilizer indicator light flashes
ON and OFF when the ignition switch is turned ON.
Troubleshooting
Step Action Yes No
1Immobilizer indicator light power supply check
1) Turn the ignition switch to ON position.
Do other warning lights come ON?Go to Step 2. Go to Step 4.
2DTC check of ECM
1) Check ECM for DTC referring to “DTC Check in Section
1A”.
Is DTC U0073, U0101, U0121 and/or U0140 detected?Go to applicable DTC
diag. flow.Go to Step 3.
3DTC check of BCM
1) Check BCM for DTC referring to “DTC Check in Section
10B”.
Is DTC U0073, U0100, U0101, U0155 and/or U1144
detected?Go to applicable DTC
diag. flow.Substitute a known-
good combination meter
and recheck. If
immobilizer indicator
light still remains OFF,
substitute a known-
good ECM and recheck.
4Fuse check
1) Turn the ignition switch to OFF position.
2) Check fuse for combination meter circuit.
Is fuse blown?Replace blown fuse,
and then check for
short.Go to Step 5.
5Combination meter power supply wire circuit check
1) Remove combination meter referring to “Combination
Meter Removal and Installation in Section 9C”.
2) Check for proper connection at terminals and wires of
combination meter connector.
3) If OK, turn the ignition switch to ON position and
measure voltage between power supply terminal of
combination meter and vehicle body ground. Refer to
“Combination Meter Circuit Diagram in Section 9C”.
Is it 10 – 14 V?Go to Step 6. Repair open in power
supply wire circuit.
6Combination meter ground wire circuit check
1) Turn ignition switch OFF position.
2) Measure resistance between ground terminal of
combination meter connector and vehicle body ground.
Refer to “Combination Meter Circuit Diagram in Section
9C”.
Is resistance 1
Ω or less?Substitute a known-
good combination meter
and recheck. If still
remains OFF, substitute
a known-good ECM and
recheck.Repair open or high
resistance in ground
circuit.
