SYSTEM CONTROL

1. Start Function

   1. The start function has different power source change patterns to suit the clutch pedal*1 or brake pedal*2 state and shift lever position*2.

      *1: Models with manual transaxle

      *2: Models with multi-mode manual transaxle

      Pattern	Clutch Pedal	Power Source Change Pattern
      A	Depressed	When the engine switch is pushed once. Off → on (IG) (after the engine is started)
      B	Not Depressed	Each time the engine switch is pushed. Off → on (ACC) → on (IG) → off

      

      Pattern	Brake Pedal	Shift Lever Position	Power Source Change Pattern
      A	Depressed	N	When the engine switch is pushed once. Off → on (IG) (after the engine is started)
      B	Not Depressed	ALL	Each time the engine switch is pushed. Off → on (ACC) → on (IG) → off
      C	Depressed	Except N	When the engine switch is pushed while in the on (IG) condition. On (IG) (engine is started or not started) → off

      

      Note:

      • Normally, the operation of the engine switch is disabled while the vehicle is being driven. However, in an emergency, by pushing the engine switch for approximately 2 seconds or more or pushing the engine switch 3 times or more in a row, the driver can stop the engine while the vehicle is in motion.

      • If no signals are transmitted to the certification ECU (smart key ECU assembly) due to malfunctions in the stop light switch assembly*1 or clutch start switch assembly*2, the engine may not start when the engine switch is pushed with the brake pedal*1 or clutch pedal*2 depressed. In such cases, performing the following procedure may enable the engine to start: 1) push the engine switch to turn the power source from off to on (ACC), and 2) push the engine switch again and hold it for 15 seconds or more.

      • The above 2 operations must be applied only in emergency situations. Under normal conditions, the engine must not be stopped by pushing the engine switch while driving. Also, the engine should not be started without depressing the brake pedal *1 or clutch pedal*2 or when the shift lever is in any position other than N.

      *1: Models with multi-mode manual transaxle

      *2: Models with manual transaxle

2. Cranking Hold Function

   1. Once the engine switch is pressed, this function operates the starter until the engine starts, provided that the brake pedal*1 or clutch pedal*2 is depressed. This prevents application of the starter for an inadequate length of time and it also prevents the engine from being cranked after it has started. For details, seeClick herefor 1KR-FE engine andClick herefor 1PP engine.

8. Battery Saving Function of Electrical Key Transmitter Sub-assembly

   1. This function cancels the signal reception waiting state of the electrical key transmitter sub-assembly, reducing the consumption of current from its battery.

   2. The electrical key transmitter sub-assembly can be placed into and taken out of battery saving mode. When the electrical key transmitter sub-assembly is in battery saving mode, the entry and start system will not be able to detect the transmitter, as the transmitter will not respond to signals from the vehicle. The function of the entry and start system will not operate if the electrical key transmitter sub-assembly is in battery saving mode.

   3. Pressing the unlock switch of the electrical key transmitter sub-assembly twice while pressing the lock switch (the indicator light of the electrical key transmitter sub-assembly blinks 4 times) selects battery saving mode for the electrical key transmitter sub-assembly.

   4. Battery saving mode can be canceled by pressing any switch on the electrical key transmitter sub-assembly.

Repeat close → open for the driver door twice-* (Driver Door: Open → Close → Open → Close → Open). Press the unlock switch of the electrical key transmitter sub-assembly twice*. Repeat close → open for the driver door once* (Driver Door: Open → Close → Open). Within 5 seconds of the step above, close the driver door. When the cancel procedure is complete, the buzzer sounds twice. When the procedure is performed again to resume the system, the buzzer sounds once.

      *: Perform all these 3 steps within 30 seconds of the previous step.

10. Key Code Registration Function

    1. The table below shows the 3 special ID code registration function modes through which up to 4 different transmitter recognition codes can be registered. For details, refer to the Repair Manual.

       Mode	Function
       Rewrite	Clears all previously registered codes and registers only the newly received codes. This mode is used whenever the certification ECU (smart key ECU assembly) is replaced.
       Add	Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter.
       Confirm	Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.

FUNCTION

1. Entry Function

   1. The entry function consists of the following functions:

      Function	Outline
      Wireless Door Lock Control	This function is a convenient system for locking and unlocking all the doors from a distance. The operation of this function is the same as that of the wireless door lock control system.
      Entry Unlock	When an electrical key transmitter sub-assembly is located in the exterior actuation area of the front door outside handle assembly, pressing the unlock switch will cause all doors to unlock.
      Entry Lock	When an electrical key transmitter sub-assembly is located in the exterior actuation area of the front door outside handle assembly and the engine switch is off (Lock), all doors can be locked by simply pressing the lock switch or glass hatch lock switch assembly.
      Back Door Open	When an electrical key transmitter sub-assembly is in the exterior actuation area of the No. 3 indoor electrical key antenna assembly (back door), the back door opens manually by simply pressing the open switch (glass hatch opener switch assembly).
      Prevention of Key Confinement	The key confinement prevention function prevents the vehicle from being locked with an electrical key transmitter sub-assembly left inside it. This function operates in 2 different situations: when the lock knob is used (keyless lock) and when the lock switch on an outside door handle is used.
      Warning	The entry and start system causes the certification ECU (smart key ECU assembly) to sound the buzzer in the combination meter and the wireless door lock buzzer in order to alert the driver.
      Battery Saving	If the electrical key transmitter sub-assembly remains within the exterior actuation area of any electrical key antenna (center pillar RH/LH or back door), the system maintains periodic communication with the electrical key transmitter sub-assembly. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could become drained.
      Key Cancel	The following key functions can be canceled by following the specified procedure. Entry unlock/lock Back door open Prevention of key confinement Warning
      Key Code Registration	A total of 4 electrical key transmitter sub-assemblies can be registered.

DIAGNOSIS

1. Start Function

   1. The certification ECU (smart key ECU assembly) can detect malfunctions in the entry and start system when the power source is on (IG).

   2. When the ECU detects a malfunction, the smart warning light blinks in yellow. At the same time, the ECU stores a 5-digit Diagnostic Trouble Code (DTC) in its memory.

   3. The 5-digit DTCs can be read after connecting the Global TechStream (GTS) to the DLC3.

   4. The entry and start system may not operate successfully if a malfunction occurs.
