PROPERLY (MANUAL OPERATION AND OPERATION
INTERLOCKED WITH KEY ARE ACTIVE)
CIRCUIT DESCRIPTION
The unlock warning switch turns ON when the key is inserted into the ignition key cylinder. The courtesy
lamp switch turns ON when the driver side door is opened. These 2 switches are monitored by the integration
relay. In order to prevent the key from being locked in, the integration relay controls door locking operation
according to the conditions of these switches so that the doors are not locked with the key locked in.

SECURITY INDICATOR CIRCUIT
CIRCUIT DESCRIPTION
Even in the disarmed state, the security indicator flashes due to a signal output from the immobiliser system.
The security indicator always flashes when it receives a signal from the immobiliser system at any time in
the armed state.
The theft warning ECU causes the security indicator to light up or blink only during the customizing function
mode or the add mode of the transmitter.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 CHECK REAR WINDOW DEFOGGER SWITCH ASSY (SECURITY INDICATOR)
(a) Remove the defogger switch.
(b) Apply 12 V positive voltage between each terminal of the
defogger switch connector, and check the lighting condi-
tion of the security indicator.
Standard:
Measurement ConditionSpecified Condition
Battery positive (+)
Terminal 8
Battery negative (±)
Terminal 1Lights up
NOTICE:

If the positive (+) lead and the negative (±) lead are in-
correctly connected, the security indicator does not
light up.

Voltage of more than 12 V will damage the security in-
dicator.

If the voltage is too low, the security indicator does
not light up.

MALFUNCTION
CIRCUIT DESCRIPTION
This DTC is output when the ECM detects errors in communication between the transponder key ECU assy
and the ECM or in the communication lines.
This DTC is also output when an engine start is attempted while the ECU communication ID between the
transponder key ECU and the ECM are different.
Before troubleshooting for this DTC, make sure that there is no DTC detected in the transponder key ECU.
If there is a key code±related DTC detected in the transponder key ECU, repair it first.
