        Tech Tips


        • Normally, the operation of the engine switch is disabled while the vehicle is being driven. However, if the engine must be stopped in an emergency while the vehicle is in motion, the driver can press the engine switch either 3 times in rapid succession or for approximately 2 seconds or more to stop the engine.

        • If no signals are transmitted to the power management control ECU due to a malfunction in the stop light switch assembly*1, park/neutral position switch assembly*1 or clutch start switch*2, the engine will not start even if the driver presses the engine switch while depressing the brake pedal*1 or the clutch pedal*2. In this case, the driver can start the engine by the following operations. Press the engine switch to turn the power source mode from off to on (ACC), and press 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 pressing the engine switch during driving or started without depressing the clutch pedal*2 or brake pedal when the shift lever is in any position other than P or N*1.

    9. Battery Saving Function


      1. Battery saving preserves the vehicle and electrical key transmitter sub-assembly batteries. The battery saving function is activated when the vehicle remains parked for a long time and when the electrical key transmitter sub-assembly is left in the exterior actuation area.

        Condition Condition Outline
        When the vehicle remains parked for a long time.

        Condition 1:

        No response from the electrical key transmitter sub-assembly for more than 5 days.


        • Door electrical key antennas and outside electrical key antenna stop emitting signals for creating the actuation area. In addition, the lock sensors or unlock sensors of all the seats are available, so touching the sensor can lock or unlock.

        		 When the engine switch is turned on (IG), the control is canceled and the system is returned to normal.

        Condition 2:

        No response from the electrical key transmitter sub-assembly for more than 14 days.


        • Door electrical key antennas and outside electrical key antenna stop emitting signals for creating the actuation area.

        • The lock sensors and unlock sensors except for the driver door are disabled.

        When the engine switch is turned on (IG), the control is canceled and the system is returned to normal. When one of the following conditions is met, the control is returned to condition 1:


        • The doors are locked or unlocked using the wireless door lock control function.

        • A door is locked or unlocked using the mechanical key.

        • Door is opened → closed.
        When the electrical key transmitter sub-assembly is left in the exterior actuation area.

        This state continues longer than 10 minutes.


        • Electrical key antenna that is detecting the electrical key transmitter sub-assembly stops emitting signals for creating the actuation area.

        The control is stopped when one of the following conditions is met:


        • The doors are locked or unlocked using the wireless door lock control function.

        • The doors are locked or unlocked by touching the lock/unlock sensor.

        • A door is locked or unlocked using the mechanical key.

      2. In addition to the above functions, the auto power off function helps to reduce drain on the vehicle auxiliary battery by turning the power source mode to off (a) when approximately 20 minutes have elapsed since the shift lever was moved to P with the power source mode on (ACC) or (b) when approximately 60 minutes have elapsed since the engine was turned off with the shift lever in P, the power source mode on (IG) and the vehicle stationary.

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


      1. This function cancels the signal reception waiting state of the electrical key transmitter subassembly, 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 electrical key transmitter sub-assembly, as the electrical key transmitter sub-assembly will not respond to signals from the vehicle. The entry and start system will not operate if the electrical key transmitter sub-assembly is in battery saving mode.

      3. Pressing the unlock button of the electrical key transmitter sub-assembly twice while pressing the lock button (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 button on the electrical key transmitter sub-assembly.

    11. Key Cancel Function


      1. The following system functions can be deactivated by using the key cancel procedure:


        • Entry Lock

        • Entry Unlock

        • Prevention of Key Confinement

        • Warning

      2. The system functions can be deactivated by using the following key cancel procedure when the engine switch is off and the driver door is closed and unlocked:

        Key Cancel Procedure

        • The procedure is as follows:


          • Press the unlock button of the electrical key transmitter sub-assembly once.

          • Within 5 seconds of the step above, open the driver door (driver door: close → open).

          • Within 5 seconds of the step above, press the unlock button of the electrical key transmitter sub-assembly twice.

          • Repeat close → open for the driver door twice* (driver door: open → close → open → close → open).

          • Press the unlock button 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. Meanwhile, when the procedure is performed again to resume the system, the buzzer sounds once.

        Tech Tips

        *: All these 3 steps are performed within 30 seconds of the previous step.

    12. Key Code Registration Function

      The table below shows the 4 special ID code registration function modes through which up to 7 different codes can be registered. The codes are electronically registered (written and stored) in the EEPROM. For details, refer to the Service Bulletin.

      Mode Function
      Rewrite Clears all previously registered codes and registers only the newly received codes. This mode is used whenever an electrical key transmitter sub-assembly or the certification ECU is replaced.
      Add Adds a newly received code while preserving previously registered codes. This mode is used when adding a new electrical key transmitter sub-assembly.
      Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.
      Prohibit Clears all registered codes and prohibits the wireless door lock function. This mode is used when a key is lost.

  4. DIAGNOSIS


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

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

    3. The indicator light warning continues for 15 seconds even after the engine switch is turned off.

    4. 5-digit DTCs can be read after connecting the Global TechStream (GTS) to the DLC3.

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