Description of Keyless Engine Start Function

Changing Ignition Mode

- When engine switch is pushed with remote controller inside cabin and brake pedal (CVT model) or clutch pedal (M/T model) released, keyless start control module compares the ID code sent by remote controller with the ID code registered in keyless start control module. When these ID codes match, keyless start control module controls ON/OFF of the ACC, IG1, and IG2 relays according to engine switch operation for switching ignition mode from "OFF" -> "ACC" -> "ON" (engine not running) -> "OFF". When ignition mode is in "ACC", "IGNITION SWITCH POSITION ACC" is shown on the display. When mode is in "ON" (engine not running), "IGNITION SWITCH POSITION ON" is shown on the display.
- For CVT model, keyless start control module judges whether select lever is in "P" range or not by the state of P position switch. This prohibits ignition mode switching from "ACC" to "OFF" with select lever in any position other than "P" range.
- Table below shows transition of ignition mode according to engine switch operation. One arrow indicates transition by pressing engine switch once.

NOTE:
- Ignition mode is automatically switched to "OFF" if there is no change in engine switch operation for 1 hour with ignition mode in "ACC" and shift position in "P" range (CVT model).
- Except in emergency situations, do not stop engine while driving.










Starting Engine

The method of starting engine is as follows.
1) When brake pedal is depressed with shift position in "P" or "N" (CVT model) or when clutch pedal is depressed (M/T model), keyless start control module (1) sends request signal to combination meter (2) through CAN communication to display "PUSH START SWITCH" on the information display.
2) Push engine switch (3) with remote controller (4) being carried.
3) Keyless start control module activates mid inside antenna (5) to send request signal to remote controller.
4) Remote controller receives request signal and then sends ID code to keyless start control module via keyless entry / TPMS receiver (6).
5) Keyless start control module compares ID code sent from remote controller with ID code registered in keyless start control module. If ID codes match, keyless start control module outputs a steering lock release request signal to steering lock unit (7). At the same time, it outputs engine start signal to ECM (8) and turns the starting motor control relay ON to activate the starting motor (9). This enables the steering lock to be released and the engine to be started.











Operation area

Engine can be started when remote controller is within mid inside antenna detection area (1).

NOTE:

Keyless engine start function may not operate when remote controller is on partition trim or instrument panel, in one of the storage boxes, around foot area of driver side or passenger side, or in door pocket, etc.










Engine Cannot Be Started

- When remote controller is not in vehicle compartment or there is only an unregistered one in vehicle compartment, keyless start control module sends immobilizer indicator light request signal, information display request signal, and warning buzzer request signal to combination meter through CAN communication to warn driver. At the same time, it turns ACC, IG1, IG2 and starting motor control relays OFF to prohibit ignition mode from switching and the starting motor from activating.
- If remote controller battery has run down or system malfunction has occurred, engine can be started by touching remote controller to engine switch as an emergency measure. Description of Engine Starting Procedure
