  4. Diagnostic procedure based on user operation
    1. Operation 1
      Operation Change the power mode to IG OFF, lock all doors, and stand 3 m or more away from the vehicle carrying the electrical key transmitter sub-assembly with you.
      NOTE: An LF band request signal is output every 0.25 seconds, which prompts each electrical key antenna (exterior antenna) to create a detection area. Each front door outer handle assembly (electrical key antenna) creates an approximately 0.7 m wide detection area.
      Waveform or output value Pulse generation (D41-12 (CLG1) - D48-11 (GND)(1))
      NOTE:
      (1) (Refer to ECM TERMINAL ARRANGEMENT  )
    2. Operation 2
      Operation Carrying the electrical key transmitter sub-assembly with you, stand 0.7 m away from the driver's door.
      NOTE: If the electrical key transmitter sub-assembly is inside the detection area, and if the key ID transmitted to the electrical key transmitter sub-assembly matches that stored in the collation ECM (smart key ECM assembly), the system enters unlock standby mode. If you touch the unlock sensor with your hand when the system is in unlock standby mode, the door unlocks. Signal transmission: Collation ECM (smart key ECM assembly) →front door handle assembly (electrical key antenna) →electrical key transmitter sub-assembly →door control receiver →collation ECM (smart key ECM assembly) →body ECM
      Expected vehicle behavior The LED on the electrical key transmitter sub-assembly blinks. If the LED does not blink, one of the parts listed in the table below might be faulty.
      Waveform or output value
      • Pulse generation (D41-12 (CLG1) - D48-11 (GND)(1))
      • Pulse generation (D40-17 (RDA) - D48-11 (GND)(1))
      • Pulse generation (D40-19 (RSSI) - D48-11 (GND)(1))
      NOTE:
      (1) (Refer to ECM TERMINAL ARRANGEMENT  )
      Possible cause Diagnosis
      Electrical key transmitter sub-assembly
      • The key ID code transmitted by the electrical key transmitter sub-assembly does not match the one stored in the collation ECM (smart key ECM assembly). Check the operation using another electrical key transmitter sub-assembly.
      • If the LED on the electrical key transmitter sub-assembly does not blink in the 0.7 m (2.3 feet) wide area beside the driver's door, perform the following:
        • Check the operation by pressing the lock/unlock button on the electrical key transmitter sub-assembly. If the door can lock/unlock, it means that a detection area has not been created. If this is the case, the problem is located in parts other than the electrical key transmitter sub-assembly or the door control receiver.
      • If the electrical key transmitter sub-assembly is faulty, you can neither start the engine nor change the power mode to ACC ON or IG ON. Normally, if you move the shift lever in P*1 and press the engine switch using the electrical key transmitter sub-assembly from the driver's seat without depressing the brake pedal*1 or the clutch pedal*2, the smart key indicator on the combination meter assembly blinks green. If the door does not open, use the mechanical key integrated into the electrical key transmitter sub-assembly to open the door.
        • *1: With automatic transmission
        • *2: With manual transmission
      NOTE: Before replacing the electrical key transmitter sub-assembly, check if the transmitter battery is not drained.
      The transmitter battery is drained.
      • Hold down the lock switch on the electrical key transmitter sub-assembly for 5 seconds and check how many times the LED blinks. If the LED does not blink, or blinks only once or twice, the transmitter battery might be drained. If the LED does not blink at all, the electrical key transmitter sub-assembly might be faulty.
      • If the transmitter battery voltage drops to 2.1 V or less before the electrical key transmitter sub-assembly starts transmitting a signal, [Yes] is displayed for [Key Low Battery] (an item under [Current Data Display & Save]).
      • If the transmitter battery voltage drops to 2.0 or less, you cannot perform any operation.
        NOTE: In low temperature environment, output from the electrical key transmitter sub-assembly decreases.
      • If the transmitter battery is drained, you can neither start the engine nor change the power mode to ACC ON or IG ON. To forcibly start the engine under this condition, place the electrical key transmitter sub-assembly over the engine switch.
      • Identify the type of the transmitter battery and check if it is installed properly.
      External radio waves
      • If a problem occurs only in certain places or at certain times, it is likely the effect of radio wave interference.
      • If the electrical key transmitter sub-assembly is faulty, it is probably due to the following reasons: the transmitter battery is drained; an electrical key transmitter sub-assembly of another vehicle is used, or; the electrical key transmitter sub-assembly is exposed to external radio waves. For the following [Current Data Display & Save] items, [Yes] may be displayed: [Unmatched Vehicle-ID], [No Response], [Unmatch Code or Form], or [ID Code Difference(Resp)]
      Collation ECM (smart key ECM assembly) -
      Front door outer handle assembly A detection area is not properly created outside the vehicle.
      • If the electrical key transmitter sub-assembly does not blink when it is located 0.7 m away from the driver's side front door outer handle assembly but blinks when it is located 0.7 m away from the passenger's side front door outer handle assembly, the driver's side front door outer handle assembly might be faulty.
      • Even when a detection area is not properly created outside the vehicle, you can start the engine by turning the engine switch ON (ACC).
      • By using the SSM3, you can check if a detection area has been created outside the vehicle. (Refer to OPERATION CHECK  )
      • Even when a detection area is not properly created outside the vehicle, you can unlock a door by pressing the unlock button on the electrical key transmitter sub-assembly.
      Door control receiver
      • If the door control receiver is faulty, you cannot lock and unlock the doors by a touch sensor operation.
      • If the door control receiver is faulty, you cannot lock and unlock the doors by a wireless unlock operation.
      • If the door control receiver is faulty, you can neither start the engine nor change the power mode to IG ON or ACC ON unless you perform an emergency operation.
      • By using the SSM3, you can check if a detection area has been created outside the vehicle. (Refer to OPERATION CHECK  )
      The vehicle battery is discharged. You can check if the vehicle battery is discharged by operating the horn.
      Other
      • If the entry function has been cancelled using the customize function, a detection area will not be created. Therefore, the LED on the electrical key transmitter sub-assembly does not blink even when you move the electrical key transmitter sub-assembly towards the front door outer handle assembly.
      • When the entry & start system is enabled, leaving the electrical key transmitter sub-assembly in a detection area created outside a vehicle door could cause the transmitter battery to become discharged. Therefore, if the electrical key transmitter sub-assembly is left in this state for 10 minutes or longer, the entry & start system automatically disables the detection area outside the vehicle where the electrical key transmitter sub-assembly is located.
      • If you inadvertently leave the electrical key transmitter sub-assembly inside the vehicle, and then use another electrical key transmitter sub-assembly to lock a door, the LED on the second electrical key transmitter sub-assembly does not blink even when you move it toward the passenger's side front door outer handle assembly.
    3. Operation 3
      Operation Carrying the electrical key transmitter sub-assembly with you, and making sure that it is inside the detection area created outside the vehicle, touch the unlock sensor on the driver's door.
      Expected vehicle behavior As the door unlocks, you get an answer-back. If this does not happen, one of the parts listed in the table below might be faulty.
      Waveform or output value
      • Pulse generation (D41-12 (CLG1) - D48-11 (GND)(1))
      • Tester conditions: Body ECM, instrument panel junction block assembly()
      NOTE:
      (1) (Refer to ECM TERMINAL ARRANGEMENT  )
      Possible cause Diagnosis
      Same failure locations as those shown under Operation 2, for cases in which the LED on the electrical key transmitter sub-assembly does not blink -
      Front door outer handle assembly (unlock sensor)
      • If you can unlock the door by touching the passenger's side unlock sensor carrying the electrical key transmitter sub-assembly with you, the driver's side unlock sensor might be faulty.
      • In normal operation, if you touch the unlock sensor, [ON] is displayed for [D-Door Touch Sensor] (an item under [Current Data Display & Save]).
      Door lock/unlock function If you cannot lock/unlock a door by operating the door control switch inside the vehicle, the door lock function might be faulty.
    4. Operation 4
      Operation Get on the vehicle carrying the electrical key transmitter sub-assembly with you, close the door, move the shift lever in P(1), and then press the engine switch once without depressing the brake pedal(1) or the clutch pedal(2).
      Expected vehicle behavior
      • The smart indicator inside the combination meter assembly blinks green (blinks slowly), and the engine status changes to ACC ON.
      • The steering wheel unlocks.

      If the smart key indicator does not blink, one of the parts listed in the table below might be faulty.
      NOTE: If you press the engine switch, the indoor electrical key antenna creates a key detection area inside the vehicle to detect the electrical key transmitter sub-assembly inside the vehicle. After receiving a request signal, the electrical key transmitter sub-assembly transmits an ID code, and the LED on the electrical key transmitter sub-assembly blinks for a short period of time. After the engine switch is pressed, if the key ID transmitted by the electrical key transmitter sub-assembly matches the one stored in the collation ECM (smart key ECM assembly), the ACC relay becomes ON, and the smart key indicator on the combination meter assembly blinks green (blinks slowly). When the power mode changes, the L code and S code(3) check process completes. The steering wheel is then unlocked, and the immobilizer is disabled. The [Immobilizer] status in [Current Data Display & Save] is changed from [Set] to [Unset]. Signal transmission: Collation ECM (smart key ECM assembly) →indoor electrical key antenna →electrical key transmitter sub-assembly →door control receiver →collation ECM (smart key ECM assembly).
      NOTE: A detection area is created inside the vehicle under the following conditions:
      • A door is open.
      • During approximately 30 seconds following the opening/closing of a door
      • The brake pedal is depressed.
      • During approximately 30 seconds following the depressing of the brake pedal
      • Immediately after the engine switch is pressed
      Waveform or output value
      • Pulse generation (D40-17 (RDA) - D48-11 (GND)(1))
      • Pulse generation (D41-3 (CLG5) - D48-11 (GND)(1))
      • Pulse generation (D59-3 (SLR+) - D59-1 (GND)(1))

      (4) (Refer to ECM TERMINAL ARRANGEMENT  )
      Possible cause Diagnosis
      Collation ECM (smart key ECM assembly) -
      External radio waves
      • If the failure occurs in certain locations or during certain periods of time, it may be due to interference from external radio waves.
      • If interference from external radio waves is suspected inside the vehicle, remove all connectors from the devices that are not part of the standard equipment, or disconnect or remove electrical devices, to check for the presence of noise.
      Indoor electrical key antenna assembly that creates a detection area inside the vehicle
      • If a detection area is not properly created inside the vehicle you can neither start the engine nor change the power mode to ACC ON or IG ON. In the event of an emergency, however, you can forcibly start the engine by placing the electrical key transmitter sub-assembly over the engine switch.
      • Using the SSM3, activate keyless access system check to forcibly create a detection area inside the vehicle. Then, place the electrical key transmitter sub-assembly inside the detection area. Short beeps sound. (Refer to OPERATION CHECK  )

      Steering lock ECM (steering lock actuator assembly)
      • If [OK] is displayed for [L Code Check] (an item under [Current Data Display & Save]) when the power mode is ACC ON, power is supplied to the steering motor for approximately 10 seconds. The ECM then sends an unlock signal to the steering motor. At this moment, the result for [Unlock Request Receive] (an item under [Current Data Display & Save]) temporarily changes from [NG] to [OK]. As the steering wheel unlocks, the ECM receives the unlock signal from the steering motor, and the result displayed for [Steering Unlock] (an item under [Current Data Display & Save]) changes from [Unset] to [Set].
      • With ID code box
        • In order for the steering wheel to be unlocked, [OK] must be displayed for [L Code Check] under [Current Data Display & Save]. This means that the ID code stored in the steering lock ECM (steering lock actuator assembly) and [S Code Check] (ID code box (immobilizer code ECM)) must match the collation ECM (smart key ECM assembly) and the ID code box (immobilizer code ECM).
      • Without ID code box
        • In order for the steering wheel to be unlocked, [OK] must be displayed for [L Code Check] under [Current Data Display & Save] This means that the ID code stored in the steering lock ECM (steering lock actuator assembly) must match the one stored in the collation ECM (smart key ECM assembly).
      (1) The ID code box is included.
      (2) With automatic transmission
      NOTE: The electrical key transmitter sub-assembly, the transmitter battery, and the vehicle battery should already have been inspected during the previous operation procedure. If not, inspect them now.
