• Security indicator lamp always blinks when the ignition switch is in any position other than ON.

NOTE:
Because security indicator lamp is highly efficient, the battery is barely affected.

ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH

1.

When brake pedal is depressed while selector lever is in the P position (CVT models), or clutch pedal is
depressed (M/T models), BCM activates NATS antenna amp. that is located behind push-button ignition
switch.

2.

When Intelligent Key (transponder built-in) backside is contacted to push-button ignition switch, BCM
starts NATS ID verification between BCM and Intelligent Key (transponder built-in) via NATS antenna
amp.

3.

When NATS ID verification result is OK, buzzer in combination meter sounds.

4.

When push-button ignition switch is pressed, BCM transmits steering lock unit unlock request signal to
steering lock unit.
• Lock/unlock position signal
• Steering lock unit lock status signal
• Steering lock undefined position signal
• Steering lock wrong code signal

5.

When BCM receives a steering lock unit unlock status signal from the steering lock unit, it stops the steer-
ing lock unit unlock request signal.

6.

When the ignition switch is turned to ON, BCM performs ID verification with the ECM. When the result is
OK, engine start is permitted.

7.

BCM detects that the selector lever position and brake pedal operation condition.

8.

When ECM detects that the start engine conditions* are satisfied, it transmits a starter control relay
request signal to BCM.

9.

When BCM receives a starter control relay request signal from ECM, the starter control relay is turned
ON.

10. When starter control relay is turned ON, IPDM E/R turns ON the starter relay and drives the starter motor.

11. When BCM receives an engine status signal from ECM, it turns the starter relay and starter control relay

OFF and stops cranking.

*: For the engine start condition, refer to “IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUT-
TON IGNITION SWITCH OPERATION” below.

IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION

The ignition switch position can be changed by the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna or when Intelligent Key backside is

contacted to push-button ignition switch, it is equivalent to the operations below.

• When starting the engine, the BCM monitors under the engine start conditions,
